360° Pollinator Garden Tour

Have you ever wondered what pollinator-supporting plants you can add to your property ?

Here’s an excellent and enjoyable way to find out.  Funded by one of our Community IPM Grants, Cooperative Extension of Putnam County created the perfect example. While you can certainly stop in to visit, (Cornell Cooperative Extension of Putnam County,  1 Geneva Road, Brewster NY.), here’s the next best thing. Or maybe it’s better because you can visit any time regardless of weather and distance!

Visit a real pollinator garden with this virtual 360 degree tour. In this curated experience, suitable for youth and adults,  go on a pollinator insect hunt, or learn about the threats to native and non-native pollinators. Master Gardener Volunteers will help you make decisions about plant and landscape choices that support pollinator abundance and diversity.

This is just one of the resources we are pleased to provide to help you help pollinators.

Find these and more on our website:

Congratulations to the crew at CCE Putnam for this unique resource!

Comments Off on Happy National Weed Appreciation Day!

Happy National Weed Appreciation Day!

It really boils down to this: that all life is interrelated. We are all caught in an inescapable network of mutuality, tied into a single garment of destiny. Whatever affects one destiny, affects all indirectly. – Dr.  Martin Luther King, Jr.

Ahhh, the weed. Despised by many, almost to the point of violence. Once, while waiting for my older child to get out of preschool, I sat in the lawn and blew dandelion heads to the delight of my infant. I’ve never forgotten the sudden manifestation of a red-faced man screaming at me about terrorizing the neighborhood. (I like to think my son was unaffected.)

The first step in IPM is determining if you have a problem. All those years ago, a large, angry man was a problem, but I contend to this day that the dandelions were not. An unknown author penned that weeds are people’s idea, not nature’s. And many through the years have found inspiration from weeds. While researching this post, I had the option of strictly sticking to quotes about weeds (don’t worry, I didn’t), but I will add a few. There are quotes about their survivability:

You can’t help but admire a plant that has adapted to lawn mowers.

  • A weed is a plant that has mastered every survival skill except for learning how to grow in rows. – Doug Larson
  • A fresh and vigorous weed, always renewed and renewing, it will cut its wondrous way through rubbish and rubble. – William Jay Smith

Quotes about weeding:

  • Plant and your spouse plants with you; weed and you weed alone. – Jean-Jacques Rousseau

And many waxed poetic about their hidden value:

  • What is a weed? A plant whose virtues have never been discovered. – Ralph Waldo Emerson
  • When life is not coming up roses, Look to the weeds and find the beauty hidden within them. – F. Young

But beyond their value as a philosophical aid, can weeds be beneficial?

In fact, what weeds you find can tell you something about the soil. Is it wet or dry? Lean or fertile? Compacted? Acidic, alkaline, or neutral? Check out the short overview from the University of Vermont, What Weeds Can Tell You. Then act accordingly.

Often, weeds we find troublesome are plants we once valued. Dandelions, garlic mustard, plantain, and burdock are examples of plants brought over and cultivated by settlers to North America for food and medicine. And there are efforts to regain that value. One doesn’t need to spend too much time on the internet to find many resources on edible weeds. Take a look at this short video, Edible Weeds | From the Ground Up, developed by the University of Wyoming Extension (which includes some precautions you should take if you want to try eating your problems away). The Northeast Sustainable Agriculture Research and Education recently funded a project looking at bringing edible weeds from the farm to the market.

These trichogramma wasp parasitized European corn borer eggs aren’t going to hatch.

There is research looking at the ecosystem services provided by weeds in agricultural settings. In their project, Integrating Insect, Resistance, and Floral Resource Management in Weed Control Decision-Making, Cornell researchers make the argument that while weeds can compete with crops, they can also benefit the entire system. They use milkweed along a field of corn as a case study. There are aphids that feed on the milkweed and produce honeydew, which benefits beneficial insects such as wasps that lay their eggs in the eggs of insect pests such as European corn borer. And that’s before they discuss the benefit to monarch butterflies.

Early flowering weeds, such as this purple deadnettle, provide an early spring food source for pollinators.

And speaking of butterflies… and bees… and other pollinators, in the write-up of a study looking at the capacity of untreated home lawns to provide pollination opportunities, they reclassified weeds as “spontaneous lawn flowers”. So much friendlier! By the way, they found 63 plant species in those lawns. In a parallel study looking at mowing and pollinators, they found that lazy lawn mowing led to more spontaneous lawn flowers leading to more pollinators. So now I have also given you an excuse to mow less. You’re welcome.

So embrace your spontaneous flowers!

If, after today, you still want to manage those plants, you can always find a plethora of resources for different settings within our New York State Integrated Pest Management website.

IPM Celebrates the New Year With News for You

We decided on a new look for our IPM Year in Review—our first-ever calendar. Who doesn’t put calendars to good use? I’ve already noted a couple of dentist appointments in mine.

And for you, dear reader, we offer our calendar sampler—four months, four topics, four new things to learn.

February:

It’s February and shivery cold—and time to pay careful attention to the nooks and crannies so inviting to the critters that call your home theirs. Do you hear varmints scurrying in the basement, the walls, the ceiling? Mice and kin (OK, rats) have taken up lodgings and are way overdue on the rent.

Block their access. Start with a look in the basement. For mice, the entryway need be no larger than a dime; for rats, a quarter. Take it from us: if their heads can fit through, their fat little tummies can squeeze through too. Found a hole? Found several? Get some sealant and fill ’em up.    https://conservesenecacounty.com/wp-content/uploads/2015/04/mouse.jpg

March:

Ah, March—when winter marches into spring. School kids are antsy to get outside. And us? We’ve got ticks on our mind. Here’s your blacklegged tick, up close and personal. Soon these ticks will be out and about; the health hazards can hardly be overstated.

So practice the drill—how to ID them, dress for the occasion, do tick checks. Planning a hike? Wear light-colored duds (the better to see you with, my dear), pull your socks over your cuffs—and as soon as you’re home, do tick checks. Got pets? Check them too.

Btw, though their common name is “deer tick,” many scientists prefer “blacklegged tick.” We’re speculating here—but could that be because otherwise people will get the mistaken notion they can catch Lyme from deer, which they cannot? Yes, deer are among the movers and shakers in the world of Lyme. But by the time they’ve donated their blood to the cause, mama tick will have dropped off and called it a day.

Regardless: these ticks have a lineage that goes way back. In fact, a fossilized tick was found in a chunk of amber where it dined on mammalian blood some 20 million years ago. It carried babesia—a disease that’s still in action today.

May:

It’s May now; summer is nearly here and the weeds are growing like—well, like weeds. Unperturbed by spray, horseweed and waterhemp are gaining ground, dramatically reducing crop yields. Regaining control over these herbicide-resistant weeds is a major issue for New York’s farmers.

Here’s one approach. With nearly 20 rubbery fingers on each hand and 20-plus hands, this cultivator earns its keep by dislodging, uprooting, and burying weeds while they’re still small. The boxy white contraption with two dark “eyes” and mounted at head height with a cable running toward the cab? That’s a camera, designed to move the cultivator left or right. It’s job? Keeping the cultivator aligned with the crop.

November:

Bed bugs are back, the scourge of small and big towns alike. No, they don’t spread disease. Yes, on some of us they leave itchy red welts—while others have no symptoms at all. But you don’t need to throw all your belongings away, we promise. IPM now offers to ultimate in How To guides: How to Get Bed Bugs Out of Your Belongings.

Your hair dryer and vacuum cleaner will be your steadfast companions in your battle to regain control over your mattresses, shoes, clothes, and electronics. The hair dryer’s gentle heat will flush the little buggers out of hiding; the vacuum cleaner sucks them up. The guide also provides instructions on how to quarantine your belongings long enough to starve them into oblivion. Bed bugs, even during the holidays, are manageable.

Let IPM help you!

2018’s Best of NYS IPM

“None of us is as smart as all of us.” –Ken Blanchard

2018 has been quite the year and we have been busy blogging, tweeting, videoing, and Facebooking about it. Here’s a recap of some of our more popular 2018 offerings:

ThinkIPM – our catchall blog and a great way to keep a pulse on what’s happening in New York State IPM.

Our most popular blog post was actually a guest blog by Paul Hetzler, CCE St. Lawrence County, Move Over, Medusa: Pretty? Poisonous! in the Caterpillar Clan. We’re big fans of his writing and this post on a venomous caterpillar caught a lot of your attention as well. (photo credit: Wikimedia Commons)

 

Are you safe now?

Ticks in February?

Ticks in the cold was also a popular topic. And relevant to now! Check out these two blog posts, Ticks don’t care what month it is and Ticks and the freezing weather. Hopefully they both convince you to keep up your daily tick checks.

While visiting our blog, you have also been checking out older posts. Our second most popular post viewed in 2018 was a 2014 post, Identifying Your Pest – with Poop?. There are a lot of budding scatologists out there.

Other IPM Blogs – Besides ThinkIPM, we have more dedicated blogs, and you don’t need to be a specialist to subscribe to them. Here are some of the more popular posts:

The Spotted Wing Drosophila blog has an obvious focus, but the post Spotted lanternfly found in two counties in NY captured the most views.

 

Biocontrol Bytes was begun at the end of 2018 and many of you have been enjoying the updates on the Creating habitat for beneficial insects project.

 

We saw a number of news reports about bed bugs in schools, so we wrote Bed bugs in schools aren’t going away in The ABCs of School and Childcare Pest Management blog. And you read it. We just wish the news reporters and commenters did too.

 

The 2017 NEWA Survey: IPM impact includes such gems as “93% agreed or strongly agreed that NEWA pest forecast information enhances IPM decision-making for their crops”.

 

Gypsy moths on Christmas trees? Check out the Tree Integrated Pest Management blog and see how it’s now a thing in the Gypsy Moth Caterpillars -Scout for them now post.

 

Facebook

When it comes to Facebook, video rules. Our most popular Facebook post was our claymation video, Life Cycle of the Blacklegged Tick (and Lyme Disease Prevention!). And, by the way, this claymation was part of a large Don’t Get Ticked NY campaign launched in 2018!

Our new Spotted Lanternfly video, Have YOU Spotted Lanternfly Egg Masses was just posted, but it has already reached the number two spot. This invasive insect is getting a lot of attention and we need your help to keep track of it in New York.

 

Twitter

We’re not surprised that our most popular Tweet of 2018 was about spotted lanternfly. Follow us on Twitter to keep up with the latest information.

 

 

 

Annual Report

This might be cheating, because it was just released and we have no data to show its popularity, but our 2017-2018 annual report is a 2019 calendar and everyone we have shown it to has been pretty excited.

Here’s a picture of the spotted lanternfly you have been hearing about.

 

 

 

 

 

 

 

So, as we raise our glasses to 2018 and look forward to 2019, include keeping up with NYS IPM Program amongst your resolutions.

Happy New Year!

Comments Off on Tick IPM – The Dog Zone

Tick IPM – The Dog Zone

December’s wintery breath is already clouding the pond, frosting the pane, obscuring summer’s memory… ― John Geddes

Winter had an early showing in New York this year. So when the temperature hit 50oF yesterday, I took the opportunity to spend some time outside. And, as I had warned people that follow me and NYS IPM on social media with this great graphic by Matt Frye earlier today, the ticks were out and about. (Side note: follow us at www.facebook.com/NYSIPM and twitter.com/NYSIPM for up-to-date information you can use.)

Now, the ticks weren’t as active as the 70 oF day last February. I had to put in a little more effort to find them. But while tick dragging, I noticed where others regularly go off the beaten track (or, rather, create their own beaten track). We’re going to call this The Dog Zone.

There’s a perfectly good paved path, but the dog print laden path is inches from the woodline.

Let’s face it. Dogs want to stick their noses into interesting places, and there just aren’t that many interesting places on the pavement. So they will take advantage of the length of the leash to get off the pavement and follow the scent trails. And the smells of mice, chipmunks, squirrels, raccoons, deer, rabbits (you get the idea), are more likely to be wafting at the edge of the woods than in the short grass. I watched dog walkers leave the pavement themselves to indulge their furry friends. Unfortunately, ticks are more likely to be in those areas.

Talk to your vet about options to protect your pets from ticks and tick-borne diseases.

Typically the dogs are between their walkers and prime tick habitat, but leaving the pavement still puts you more at risk if you are not taking preventative measures. And let’s not forget to protect your dogs too. There are multiple products out there including different topical and oral products as well as collars. These are described in our Tick FAQ under What should I do to protect my pet from ticks?. (Funny story, numerous people have asked me if they could put tick collars around their ankles. Just… no. You can, however, apply permethrin to your own clothing.)

But the really important message here is that ticks are active during the winter. And even if the air temperature is less than 37oF, a protected, sun-exposed area next to a woodline can be significantly warmer. Last week a site we were monitoring had an air temperature of 40oF, but the ground temperature was 50.6oF. So I will end by emphasizing the need to protect yourself from ticks year-round and conduct a tick check EVERY DAY.

New Posters Available from Don’t Get Ticked New York

Many of us have snow or slush on the ground. While this changes tick activity, it doesn’t mean tick and tick-borne disease risk is over.  We’re pleased to provide our newest Tick infographic posters for Farmers, Hunters and Children.  Members of the community IPM team continue to gather all the latest information on tick activity and tick-borne diseases regardless of the season. All thirteen posters are listed below, with direct links to printable PDFs.

Today, we’ll highlight our recommendations for HUNTERS!

This poster, featuring a hunter, shows how to check yourself for ticks, and safely remove a tick.

Part of that effort involves creating resources to help educate New Yorkers, as well as giving talks around the state and taking part in online webinars.

Don’t Get Ticked New York offers thirteen infographic posters.  Along the right side of our webpage https://nysipm.cornell.edu/whats-bugging-you/ticks/, look for TICK INFOGRAPHIC POSTERS which will link you to ECommons and the pdfs for all of our posters. Where? See below!

Sorry, I Can’t Help You [grow that horribly invasive plant].

Today’s post is from Matt Frye. FYI: (He didn’t just show up on our door talking ticks or rats! And we’re glad he escaped the vines to join our program.)

Kudzu is an invasive vine that was introduced from Japan to the United States in 1876. In its heyday, kudzu was planted extensively throughout the southeastern US, where it was touted for its ability to prevent soil erosion on embankments, restore soil nitrogen (it’s a legume), and provide high quality forage for livestock. Unfortunately, like many invasive organisms introduced outside of their native range, kudzu became a pest species due to its rapid growth rate and the ability to shade out existing vegetation.

Kudzu was planted extensively on slopes for erosion control.

Based on the detrimental effects of this plant and the cost of management, kudzu is listed as a noxious weed in several states. It has also been the subject of extensive research by the US Forest Service, including my graduate research at the University of Delaware, which examined the potential for biological control of kudzu using insect natural enemies.

Kudzu vines grow up trees, over bushes, and create a dense cover of foliage that kills other plants.

In 2014 I published a slide set describing my work and experience with kudzu: why it’s a pest, some of its ecological impacts, common misconceptions, how it was grown, and how it can be killed. Since publishing this document, I have received dozens of requests for more information about the plant. What do most people want to know? How to grow it! This has been for art installations, research on allelopathy, a test to determine if kudzu can grow in zero gravity (yes, kudzu literally will be sent to space), genetic studies and for use as wildlife forage.

The last request for information to grow kudzu in New York was most alarming, and led to communication with colleagues at the New York State Department of Environmental Conservation. As it turns out – there is a regulation (6 NYCRR Part 575) that prohibits the possession, transport, importation, sale, purchase, and introduction of kudzu and other prohibited and regulated invasive species in New York (thank goodness!). And while there is a loophole for permits to be issued, these are strictly for “research, education or other approved activities.”

Can I help you to manage the plant, and offer suggestions for what to do in spaces where kudzu has been cleared? You bet! Can I help you to grow the plant for research purposes? Sure. But if your interest in growing kudzu is for non-academic purposes –I can’t help you. Sorry (not sorry).

Comments Off on Hummingbirds as Pest Management Partners?

Hummingbirds as Pest Management Partners?

A recent NYS Berry Growers Association newsletter highlighted Dr. Julie Carroll’s work on hummingbird interactions with spotted wing drosophila (SWD). Robin Catalano, author of the article, referenced two posts from Julie’s SWD blog. Today, we’re offering a taste (a one part water, four parts sugar taste), but encourage you to visit each post for more detail.

(CC BY-SA 2.0) Flickr “Mike’s Birds”

It all began when, in her 2014 blog post entitled Hummingbirds, Julie shared an article from Good Produce, Berry Growers Sharing Great Ideas by Charlie O’Dell: “Unusual Way to Control SWD”, one grower’s use of hummingbird feeders to attract these beautiful, pugnacious, and voracious birds. O’Dell wrote, “Robert Hays of Hays Berry Farms at Dumas, MS, installs 25 hummingbird feeders per acre in his six acres of blackberries and fills each with a plain, clear, sugar-water solution. He estimates there are more than 500 hummingbirds flying around his fields on picking days, some even landing briefly on pickers’ arms or hats. Between his beneficial insects and his hummingbirds, he has not had to spray.”

Do you know that hummingbirds will eat up to 2,000 small insects per day when feeding their young?

A hummingbird’s diet consists mostly of flower nectar and insects. Nectar provides sugar for their high metabolic rate, while insects provide protein, amino acids, and necessary vitamins and minerals. Besides fruit flies, hummingbirds consume (in one effective swallow) tiny beetles, flies, gnats and mosquitoes. To bring these beauties near, many people supplement natural nectar sources with a solution they purchase or mix on their own. It’s important to sterilize the feeders often or boil the solution to reduce yeast or bacterial growth. The warmer the temperatures, the more frequently the nectar should be changed. Oh, and skip the red dye.

Before commencing her field trial, Julie consulted The Cornell Lab of Ornithology’s FAQ’s . We suggest you do the same!

In short:

Use fairly small feeders at first, and change sugar water at least every couple of days. During hot, dry weather, when hummingbirds risk dehydration, it’s best to dissolve no more than a quarter cup of sugar per cup of water. (Up that to one third cup during cold, rainy weather.)

To reduce ant interference, use hummingbird feeders that have a center “moat”. Another option is coating the hanger rod with petroleum jelly.

Hummingbirds can consume 100 percent of their body’s weight in sugar water or nectar every day, in addition to as many as 2,000 tiny insects! Before migration, it’s not unusual for a hummingbird to double its weight, adding a huge amount of fat to power the long journey.

Because of competition for food, it’s best to set out a few small feeders rather than one large one. Adult males defend their territories during nesting season, so you’ll see fewer in midsummer when nesting females are busy incubating.

Hummingbirds as Pest Management Partners?

Over the last four years, Julie’s research in raspberry plots at Cornell AgriTech has shown promise as an alternative tactic to reduce SWD impact. Her recent post Hummingbirds May Reduce SWD addresses her findings.

Julie saw fewer SWD caught in traps where hummingbird feeders are located, compared to more being caught where there are no hummingbird feeders, in a transect along a raspberry planting.

Intrigued, a blueberry grower and a raspberry grower each gave it a try this past season to see if such an effort was feasible. Both growers cleaned the feeders and changed the sugar solution twice per week to keep the hummingbirds well fed and active within their plantings. Were they successful? We can tell you that, during a workshop held on one site, multiple growers considered adding this ‘tool’ to their pest management toolbox.

At the August, 2018 workshop held in Salem, NY, several of the tiny birds were seen dashing about.

Preliminary data analysis for 2018 shows that when SWD numbers are very low or very high, there is little to no difference in the number of SWD caught in Scentry traps placed in area of the field with hummingbird feeders compared to those in the area of the field without feeders. However, when numbers are moderate, there was a difference. Along a transect down the length of the field, the trend was fewer SWD in the hummingbird feeder area compared to the no-feeder area, as shown in the chart.

While placing and maintaining 25 hummingbird feeders per acre (the number of feeders used in her research) may be a bit arduous for some growers, there are other ways to attract hummingbirds to your berry planting. Allocate space for their preferred flowering plants, such as alternating rows of Monarda (bee balm).

Unfortunately, SWD “season” is much longer than that of our hummingbird helpers. When SWD populations explode in late summer, they remain difficult to control. By now, these lovely flying predators have likely flown South on their journey to the Yucatan peninsula in Central America.

What does this all mean to you? Growers like Robert Hays watched what was going on in his fields and tried something new. This is a key tenet of Integrated Pest Management. Scouting and using innovative methods and multiple approaches can work together to reduce pests and pesticide use.

Spotted Lanternfly: A Foe You Should Know

Ryan Parker, NYSIPM Program/Extension Aide II, has spent plenty of hours facing Spotted Wing Drosophila. Today he’s discussing the newest spotted pest.

Tree of heaven. Photo by Chuck Bargeron, University of Georgia, Bugwood.org

Tree of heaven (Ailanthus altissima) is just heavenly to a spotted lanternfly (Lycorma delicatula). This invasive planthopper is sadly all but exclusive to that invasive tree, but has been found on stone fruit, blueberries, grapevine, and a smorgasbord of 70+ species as hosts. Its ability to use favorites such as hop vines and black walnut as preferential hosts for its life cycle will continue to be studied.

Perhaps it would be more accurate to call the spotted lanternfly (SLF) by its alternate name, Chinese blistering cicada. Acting to blister, fester, spread out its cute little wings and become personified as new breed of supervillain. Black widow please step away, Hollywood + spotted lanternfly = horror-able.  All puns aside, everybody loves facts.

The insect has been found in 2014 in PA (now at infestation levels), DE (2018), NJ (2018), VA (2018), and NY (2018). In New York, only one insect was found at both locations (Albany and Penn Yan). NYS citizens who were knowledgeable in the identification of the insect reported the finding, proving that awareness of this pest will play a crucial role in limiting its spread.

SLF is aesthetically pleasing.  Case in point:

Photo by Lawrence Barringer, PA Dept. of Agriculture, Bugwood.org.

Looks aside, its true colors show when its presence leads to crop loss, increased maintenance, and management costs. Don’t forget the reduction of a person’s quality of life and hazardous working conditions.

These insects, with all life stages present, mass on a given plant, sucking sap through their piercing-sucking mouth parts. Unlike the earlier instars, older SLF can pierce through thicker tissue. They do not feed directly on fruit, but may affect fruit quality.

 

 

Mass of lanternflies on tree. Photo by Lawrence Barringer, Pennsylvania Department of Agriculture, Bugwood.org

While feeding, spotted lanternflies’ honeydew excrement encourages the growth of sooty mold that builds up on leaves, fruit, and around the bases of trees–especially if infestation levels are high.  The presence of a fermenting odor caused by SLF feeding damage, and the sweetness of excreted honeydew also attracts nuisance insects, including wasps and flies. And sooty mold can become slippery. There is great concern about the sheer numbers of insects, because SLF abundance can be problematic for agricultural machinery and harvested products.

 

Spotted lanternfly lays eggs on virtually any smooth and strong surface, including plant material, stones, bricks, metal, and plastic. Thus, egg masses can be spread easily and unknowingly, and their dispersal can occur through practically any mode of transportation.

One generation occurs per year: adults develop in July, lay eggs from September-November. Overwintering egg masses—each containing 30-50 eggs—are usually covered in a waxy brown substance resembling mud. First instar nymphs emerge between May-June. First three instars are black and white; the fourth acquiring red pigments.

There is no current lure for SLF. Sentinel trees of tree of heaven are used to monitor, trap, and kill insects with systemic insecticides. Wrapping trees trunks with sticky bands, or scraping off egg masses can help. Or simply squish the nymphs and adults.   

DEC Press Release: Think You Found a Spotted Lanternfly in New York?

Anyone that suspects they have found SLF is encouraged to send a photo to spottedlanternfly@dec.ny.gov. Please note the location of where the insect was found, egg masses, and/or infestation signs. Department of Environmental Conservation (DEC) and Dept. of Ag and Markets (DAM) also encourage the public to inspect outdoor items such as vehicles, furniture, and firewood for egg masses. Anyone that visits the Pennsylvania or New Jersey Quarantine Areas should thoroughly inspect their vehicle, luggage and gear for SLF and egg masses before leaving and scrape off all egg masses.

A Smartphone application is also available to help citizens and conservation professionals quickly and easily report new invasive species sightings directly to New York’s invasive species database from their phones. For more information, visit http://www.nyimapinvasives.org/

Comments Off on Pest Exclusion: An Old Concept With New Life

Pest Exclusion: An Old Concept With New Life

The Scientific Coalition on Pest Exclusion, or SCOPE, started as an idea from industry expert and world-renowned rodentologist, Dr. Bobby Corrigan. Well-versed in pest management literature, Bobby’s reading of a particular sentence in Hugo Hartnak’s 1939 text, “202 Common Household Pests,” resonated with a concept he was thinking and teaching about all along, “We should have little trouble with vermin if builders would hear and understand the ‘language’ of vermin and do a better job in eliminating their entrances and hiding place.

Indeed, Hartnak was promoting pest exclusion. But the concept never really took off, in part due to the expansion of available synthetic pesticides around the same time, which revolutionized the industry and ‘protected’ homes by directly killing pests.

Fast forward more than 60 years to the early 2000’s, when federal regulation changes and new restrictions were imposed on rodenticides, pyrethroids, and indoor use of organophosphates. These changes to chemical pest control provoke careful consideration of the long-term solutions that make sites less attractive to pests and keep them out – two essential IPM techniques of sanitation and exclusion. Sanitation removes sources of food and water that sustain pests, but requires cooperation from clients to do their part in maintaining a clean environment. On the other hand, exclusion represents an opportunity for the pest management industry to perform work on a semi-regular basis that seals openings and prevents pests from moving into and within structures.

Dr. Bobby Corrigan identifies an unprotected grate with gaps large enough for Norway rats to enter.

As a rodentologist, Dr. Corrigan understands that human-pest interactions are more than a nuisance – they can represent a real risk to human health. Consider the recent publications that identify house mice in apartment buildings as reservoirs of pathogenic bacteria and hosts to a diversity of viruses.

Traditional pest management techniques that rely on trapping or killing pests will not necessarily prevent these interactions – but exclusion can. Dr. Corrigan’s vision is to advance the pest management industry by increasing adoption of exclusion practices to limit human-pest interactions.

Starting in 2013, Dr. Corrigan and Dr. Steve Kells (University of Minnesota) formed a coalition of experts to not only promote pest exclusion, but to advance the science of this field through research. Subsequently, two Scientific Coalition on Pest Exclusion working groups were funded by Regional IPM Centers. The first, funded by the North Central IPM Center was led by Kells, and focused on pest exclusion in commercial and industrial structures. A group funded by the Northeastern IPM Center was headed by Dr. Jody Gangloff-Kaufmann (NYS IPM Program, Cornell University) and explored exclusion in residential structures.

What building materials, structures, or design features lead to pest entry or harborage? This concrete hollow block was home to mice, as evidenced by the sebum or rub marks, and could be sealed with cement.

Together, the working groups collected data on building design, materials and other factors that might help to predict common pest exclusion issues. With an understanding of what materials fail in which situations, this can help the pest management industry in identifying common entry points, or provide insight to construction professionals for opportunities to reduce indoor pest problems. Core members also contributed to a literature review of pest exclusion (both items are still in progress). In March 2018, SCOPE members participated in a session at the 9th International IPM Symposium in Baltimore, MD to discuss different ways of promoting  exclusion to enhance adoption. “Partnerships to Strengthen the Role of Exclusion in IPM” explored opportunities to include exclusion in efforts such as building renovation, weatherization, fire proofing, asthma reduction, and compliance with regulations such as the Food Safety Modernization Act and SOX compliance.

SCOPE members continue to provide training on pest exclusion techniques as a way to promote this critical and effective IPM strategy. The website includes articles from trade magazines and resources such as inspection forms to help individuals11 or companies develop their exclusion program.
