Don’t Make Your Own Tick Tubes

“Frugality, I’ve learned, has its own cost, one that sometimes lasts forever.” – Nicholas Sparks

Commercially available “tick tubes” are tubes filled with permethrin-infused cotton. Mice take the cotton to line their nests and are treated for ticks every time they return home. It’s estimated that a typical ¼ acre yard needs six tubes twice a year, with a 12 pack costing ~$45 . Although this cost isn’t excessive, there are many videos and articles on making DIY tick tubes to help people save money. But what is the actual cost?

A dozen tubes covers about a 1/4 acre for $45.

3 Reasons Why Making Your Own Tick Tubes is a Bad Idea:

1) They probably won’t work.

A pesticide product contains inert ingredients that help the active ingredient (in this case, permethrin) perform properly for the uses listed on the product label. The formulation used in commercially available tick tubes is uniquely suited for controlling ticks on mice. Other permethrin formulations are designed for other uses which are specifically listed on the label.

2) You could be putting yourself, others, pets, nontarget animals, and the environment at unacceptable risk.

Tick tubes target ticks attached to field mice. When spending time in the nest, mice expose themselves to the tick-killing products.

Tick tubes target ticks attached to field mice. When spending time in the nest, mice expose themselves to the tick-killing products.

The EPA will register the use of a pesticide only if rigorous safety testing shows it will “pose no unreasonable risks to people or the environment when used according to label directions.” Only those uses listed on a pesticide label have met this standard, and making your own tick tubes is NOT a use listed on the label of any permethrin product. One potential risk: Permethrin is highly toxic to bees. Bumble bees often nest in abandoned mouse burrows, so making your own tick tubes could harm these important wild pollinators.

3) It is against the law.

Because of Reason #2, the first sentence in the Directions for Use section of all permethrin products is “It is a violation of federal law to use this product in a manner inconsistent with its labeling.” Which, by the way, also means it is against your state’s laws.

Commercially available tick tubes cost more because it takes time and money to develop the right mix of ingredients and conduct the required safety testing to ensure that the product will control ticks without putting people, pollinators, and the environment at risk. DIY tick tubes that pose greater risks while providing poorer control of ticks are hardly a bargain; be sure to use the real thing.

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!

Pests, Pesticides and Proposals: Funding IPM Community Projects

Pests and pesticides—both can pose problems to our health, our environment, and our economy. At the New York State Integrated Pest Management Program (NYS IPM), we help New Yorkers address those problems safely and thoughtfully. How? Through innovative biological, cultural, technological, and educational practices. IPM, in a word.

Community IPM takes place in settings as varied as school buildings and grounds; residential and office buildings; gardens, parks and landscapes; and golf courses and right-of-ways. Now we invite grant proposals from qualified New Yorkers who want to develop, evaluate, or demonstrate feasible IPM methods. Budgets must not exceed $8,500. Our deadline: April 6, 2018. Funds must be spent by February 28, 2019.

The German cockroach needs no introduction. If it can get on your fork, it can get in your food. Credit Clemson University, USDA.

All projects must accomplish one or more of the following:

  • develop, advance, test or refine new IPM strategies;
  • demonstrate a link between IPM practices and reduced risk to human health or pesticide residues;
  • measure the positive change or potential impact of IPM practices or adoption, or survey current IPM knowledge;
  • develop Community IPM resources, such as brochures, websites, fact sheets, manuals, and apps for smartphones and tablets;
  • develop IPM educational programs, such as workshops or curriculum;
  • educate others about IPM through outreach and demonstrations.

Audiences could include school administrators, teachers and students; landscape and structural pest management professionals; vector control specialists; municipal employees; nuisance wildlife control operators; golf course personnel; arborists; right-of-way managers; day care operators—just about anyone, in fact. We encourage projects that reach new audiences or develop new partnerships.

Two years. Yup. Ticks know how to make good use of their time.

Our Community IPM priorities include: develop or demonstrate solid strategies for dealing with rodents or cockroaches; develop, confirm or promote methods to lessen the impact of ticks; research, demonstrate or create outreach projects that promote pollinator health and conservation; and research and demonstrate alternatives to imidacloprid on lawns and athletic fields.

Yes, there are plenty more. But for 2018, these four are our greatest needs.

Got Questions? We encourage you to discuss your ideas with NYS IPM community staff, including:

  • coordinator: Jody Gangloff-Kaufmann, Long Island, 631-539-8680, jlg23@cornell.edu (Do you work outside Cornell University and Cornell Cooperative Extension? Get in touch with Jody Gangloff-Kaufmann.)
  • educator: Lynn Braband, Rochester, 585-753-2562, lab45@cornell.edu
  • educator: Amara Dunn, Geneva, 315-787-2206, arc55@cornell.edu
  • educator: Matthew Frye, Westchester, 914-285-4633, mjf267@cornell.edu
  • educator: Joellen Lampman, Albany, 518-441-1303, jkz6@cornell.edu

  • educator: Brian Eshenaur, Rochester, 585-753-2561, bce1@cornell.edu

And consider: the most common critiques of past proposals have been that the budget lacked in clarity, explanation or justification—and those seeking grants didn’t discuss projects ahead of time with IPM staff.

Comments Off on Ticks and the freezing weather

Ticks and the freezing weather

“That is a bracing cold, an invigorating cold. Lord, is it cold!” – Sheldon Cooper

It is inevitable that when the temperatures drop below zero we are asked “Will this extended period of extremely low temps kill off ticks?”

First, the bad news. We do not expect the cold to directly affect blacklegged or dog ticks as they are adapted to this climate and will survive just fine under the blankets of leaf litter and snow.

The good news, followed by some bad news, is we are basically looking at a reversal of the large quantities of ticks in 2017 that began in 2015 when oaks in New York underwent a mast seeding event. (In simple terms, there was an enormous amount of acorns on the ground across the state. If you want to delve more deeply into the mast year phenomenon, check out Mechanisms of mast seeding: resources, weather, cues, and selection.) Abundant quantities of food led to a large quantity of small mammals in 2016. Large numbers of small mammals led to a substantial number of ticks in 2017. Researchers at the Cary Institute of Ecosystem Studies have decades of field research to back up the relationship, and lag time, between mast years and Lyme disease risk.

Which brings us to the current frigid weather, and probably even more importantly, the ice under the snow, and how it will impact small mammals. Animals that have a harder time finding food are more likely to (in order of lessening consequences) die of starvation, succumb to other stresses such as disease or predation, fail to mate, give birth to fewer young, and give birth less often. In a nutshell, there should be fewer hosts come spring. And fewer hosts eventually lead to fewer ticks. Good so far.

But there is some bad news, too. During the time of high tick numbers and fewer small mammal hosts, each of us, and our companion animals, are at greater risk of coming into contact with questing ticks. So as soon as the temperatures rise into the mid-30s (and we know you will be out enjoying the veritable heat wave), ticks will be questing and we need to Steer Clear of Ticks and the Diseases They Carry — the IPM Way.

I am afraid the search for a reason to fully embrace the cold continues.

Comments Off on It’s (still) tick season — and will be evermore

It’s (still) tick season — and will be evermore

Sorry to bring up a sore subject, but it’s still tick season. And will be all year round. What … during winter? Really? Yes. But for starters here’s your pop quiz:

A tick’s lifespan is

  • three months
  • ten months
  • twenty-four months (that is, about two years)

The best way to remove a tick is to

  • swab it with nail polish
  • hold a hot match to its behind
  • pull it straight up with fine-point tweezers

Even 15 million years ago, it was tick season. Trapped in amber, this tick carries Lyme-causing bacteria. (Photo credit Oregon State University.)

But back to our intro. Here’s the scoop: an adult female that hasn’t yet managed to grab hold of a large animal (think deer — or person) to get that all-important blood meal (can’t lay eggs without it) doesn’t want to wait around till a sunshiny summer day next year, because by then its number is up. Besides, the mice, chipmunks or birds it fed on earlier in its life cycle have only so much blood to go around. So that tick stays just below the soil where tall meadow flowers or low shrubs grow. Waiting. Waiting for a thaw barely long enough for it to scramble up one of those stems.

Waiting for the cues that tell it a warm-blooded animal is at close range. An animal that might be you.

And now for a look at our quiz. A tick’s lifespan? Your answer is (drumroll) C: upward of two years. Here’s how it works: Ticks spend a lot of time in dormancy, aka diapause. Eggs are laid in spring, tucked away out of sight. If some critter doesn’t find and eat them, they’ll hatch during summer as larval ticks (seed ticks, they’re sometimes called). Larval ticks are not infected with Lyme when they hatch — indeed, they’re pure as the fallen snow.

Meanwhile if likely hosts — those mice, chipmunks or birds — wander by, the ticks latch on. And if a host is already infected with Lyme disease or any of its nasty co-infections, those larval ticks, pure no more, are infected too.

Look close and you’ll see that spring, summer, fall, winter … every season is tick season. (Image credit Florida Dept. Health)

Larvae that make it this far morph into nymphs, and it’s diapause season again as the nymphs wait it out till the following spring. Assuming these ticks are now carriers —and about 25% will be — spring is the worst time of year for us. Because these ticks are tiny enough (the infamous poppy-seed stage) that they’re easy to overlook. If you get bit, ipso facto — you get Lyme (and quite possibly a co-infection too).

Things slack off in late summer as surviving nymphs enter a diapause that lasts till the following spring. But you can’t let down your guard, since by mid-fall through winter you’ve got those adult ticks to consider. The good thing (if “good thing” there is)? While half of these sesame seed-sized ticks are infected, they’re also easier to spot and remove.

Our second  quiz item? If any of these strike you as valuable folk wisdom, strike the valuable part and know it ain’t so. Nail polish? Matches? Don’t even think of it. Those first two items are just likely to tick that tick off — and it’ll vomit its gut contents into you in its hurry to get out. That is, if it can get out quickly; if it’s really drilled in, it has downloaded a cement-like substance to anchor itself. It takes some doing to disengage, however persuasive the nail polish, burnt match, or myriad other folklore remedies. (Twisting it is another no-no that comes to mind, mainly because someone asked me about it mid-way through this post.)

Pointy tweezers, held right against your skin and gripping the mouthparts, are the way to go. (Image credit tickencounter.org)

If you value your health, get yourself some pointy tweezers, sold for needlepoint and other crafts, and carry them with you always in your bag, backpack, or whatever you haul around. Grasp that tick as close as you can get to your skin and pull steadily. Did its mouthparts remain glued within? Not to worry — the tick will feed no more. And before too many days go by, your exfoliating skin (that’s when the top layer of skin cells drift away) will exfoliate them in turn.

With ticks, prevention can include everything from doing routine tick checks to wearing repellent clothing when you’re outdoors — regardless the season. And you can’t do much better than this for advice about dressing right.

Meanwhile here’s your catchphrase: 32, ticks on you. “32” as in 32°F. Stay watchful — and stay safe.

Comments Off on Getting ticked? Bummed about Lyme disease? You’re not alone

Getting ticked? Bummed about Lyme disease? You’re not alone

An NYS IPM Your NEWA Blog entry dropped into my inbox a couple of days ago — and since the entire conversation on my bus ride into work today was about ticks, a topic no one seemed to tire of, I just had to borrow from it for this post.

Here’s how it begins:

“Getting ticked? You’re not the only one.” That’s my colleague Dan Olmstead speaking. He continues:

“I was at Empire Farm Days working the New York State IPM Program booth last week. What do you think the most asked-about topic was?

“Every question I answered was about ticks. Ticks are most well-known as carriers of Lyme disease and they are on the rise. Changing weather and climate patterns could be partly to blame. Growing seasons are getting longer and ticks have more time to develop.”

Dan goes on to explain that range expansion is another likely factor coinciding with increasing numbers of mice and deer. These critters do well in fragmented habitat, whether it’s overgrown field, hedgerows — or expanding suburbs.

Mice infected with Lyme transmit it to the young ticks that feed on them. Meanwhile deer (birds too) pick up ticks in one place and ferry them to new, perhaps un-infested locations — making them complicit in transmitting Lyme disease despite the fact that, at least on deer, Lyme-free ticks (and yes, such ticks exist) won’t contract Lyme by feeding on deer.

But the black-legged tick (aka deer tick), host to Lyme disease and several other nasty co-infections, isn’t the only dog in the fight. It has friends — as it were. Here (courtesy the Centers for Disease Control) are the ticks we see and the most common diseases now associated with them:

Black-legged Ticks  Lyme, Anaplasmosis, Babesiosis and Powassan virus
Lone Star Ticks    Erlichiosis, STARI, and Tularemia
American Dog Ticks   Tularemia and Rocky Mountain Spotted Fever
Brown Dog Ticks Rocky Mountain Spotted Fever

When Empire Farm Days rolled around in early August, the tiny nymphs — the most dangerous stage for us humans — were still at it, still clambering onto the tall grasses and low brush or meadow plants that they’d perched on most every chance they got since May. They were waiting for the right host to come by. It’s called questing. And yes, these ticks are — metaphorically at least — on a quest that for them means life or death. (Most die but plenty remain.)

True, by now in late August, their populations have peaked. But even so they’re still eight-armed and dangerous.

Eight-armed? OK — make that eight-legged.

And typically by early August, it’s too hot and dry anyway for ticks to quest for hosts. But by early August this year, our colleague Joellen Lampman hadn’t seen the usual summer decline in black-legged tick questing. Ticks like to quest when humidity is greater than 85%, and 2017 assuredly hasn’t been stingy on that account.

Got ticks on your mind? Bummed because you’re stuck inside and feel like you can’t get out in the woods like you used to? Worried because deer have found your neighborhood, regardless how populated your neighborhood? Wondering how best to protect yourself? Seek no further: Tick Encounter is your one-stop shopping for everything you need to know. Check it out.

Comments Off on Rat czar Robert (Bobby) Corrigan earns IPM award

Rat czar Robert (Bobby) Corrigan earns IPM award

For Robert Corrigan the moment was pivotal. Enchanted from childhood by the story of iconic oceanographer Jacques-Yves Cousteau, Corrigan enrolled at the State University of New York at Farmingdale with one dream: to be the next Cousteau. That changed the day biology professor Austin Frishman was a substitute teacher. So riveting was that one class that Corrigan immediately switched majors to Frishman’s specialty — pest management.

Pest management on a par with oceanography? Metaphorically, yes — for pests inhabit unseen worlds of their own. Corrigan had stumbled into a vocation that’s earned him accolades wherever pests and people collide.

Grates aren’t so great at keeping rats out if a hole has rusted through.

Now for his unparalleled integrity and expertise, Corrigan has earned an Excellence in IPM award from the New York State Integrated Pest Management Program (NYS IPM) at Cornell University.

NYS IPM’s Matt Frye says Corrigan was pivotal to his own life. “Bobby inspired me to pursue pest management as a passion, not just a livelihood,” Frye says. “I’m not alone. If you’re in roomful of pest management pros when Bobby speaks, and you see light bulbs blinking on all over the place, you get a feel for the impact he has had — not just in New York, but around the world.”

Corrigan is best known for his work with rats, and it’s no wonder. “Bobby’s Rodent Academy is a golden experience, an epiphany of information,” says Gil Bloom, Director of Public Affairs at the New York Pest Management Association. “That he gives out his email to his students is a risky gambit few would take. But this is the man.”

On the surface, Corrigan’s approach is simplicity itself. Keep parks, building foundations, alleyways and streets (not to mention kitchens) clear of all dropped or discarded food scraps, and you’ll put a serious dent in how many rat complaints you get. Daunting, perhaps, but doable.

In his work with the New York City Department of Health, Corrigan took the time to really listen to people, says Caroline Bragdon, director of Neighborhood Interventions. “His greatest achievement was integrating the people management part. He was so graceful in sewing together the layers of our bureaucracy to create a working, science-based program.”

Now Corrigan, a founding member of the Scientific Coalition On Pest Exclusion (SCOPE 2020), brings decades of field experience and data to the cause. “Bobby’s breadth and depth of knowledge are key to crafting promising new ways to prevent pests from taking refuge in buildings and public places,” says Jody Gangloff-Kaufmann, chair of SCOPE and coordinator of Community IPM with the NYS IPM Program. “Once these methods are in place, we can say goodbye to chronic pest infestations.”

“Bobby is young to be a legend, but it’s true,” says Jennifer Grant, director of the NYS IPM Program. “From rats to roaches, he’s an expert at preventing, excluding and removing urban pests. He knows the community is key to success, so he involves everyone along the way—always the consummate teacher.”

Corrigan received his award at the Food Processing Sanitation and Pest Management Workshop on February 7 in Rochester, New York.

Comments Off on Fighting Waterbugs — with Water

Fighting Waterbugs — with Water

Plumbing issues lead to pest problems — there’s little doubt about that. Leaks offer standing water to rodents, and clogged, scummy drains are breeding sites for flies. How curious that one of the most common plumbing-related pest problems I see is drains and pipes without water.

Unused, uncapped drains are an open door for cockroaches and more.

Unused, uncapped drains are an open door for cockroaches and more.

Case Study
At a multi-story office building, workers reported the presence of waterbugs, aka American cockroaches, on unconnected floors. Sanitation at the site was great, and no obvious leak created harborage for cockroaches: both excellent IPM practices. But a thorough inspection uncovered an unused bathroom on one floor where the water had been shut off during renovation. Not only could we smell sewer gasses — this bathroom contained several dead American cockroaches, suggesting this was the source for that floor. On another floor a drainpipe in a mop closet was open, and we could see cockroach frass.

A drain trap — and never mind the large gap at the wall. Exclusion is an entirely different topic.

A drain trap — and never mind the large gap at the wall. Exclusion is a whole different matter.

Plumbing Traps 101
If you’ve ever looked under a  sink, you’re familiar with a plumbing trap: that U-shaped pipe that changes the flow of water from vertical to horizontal. Its job: to create a water seal that prevents odors and harmful sewer gasses from escaping into the living or work space. Each time the drain is used, fresh water replaces standing water in the trap to maintain a permanent seal.

Uncapped and unused.

Uncapped, unused — except as a highway for pests.

As side benefit, this design deters pests from using pipes to move within or between buildings. Sure, cockroaches and rodents (especially rats) can overcome plumbing traps by crawling through a small amount of water (see National Geographic video on rats in toilets). But when drains are regularly used, they’re unlikely to harbor pests.

Drain Fails
Problems with trap seals occur when drains are infrequently used and water evaporates over time, or if drains are clogged with debris. Floor drains are susceptible to drying out if

  • no one wet-mops the floors
  • they’re in production areas with lots of small spilled items or
  • they’re near a deep fryer
Water cannot penetrate drain grates clogged with dirt and debris. This drain should be cleaned (drain brush or shop vacuum) and flushed with water.

Water can’t penetrate clogged drains. Clean (drain brush or shop vacuum) and flush with water.

Inspection Tips and Solutions
Another core IPM practice: owners or facilities maintenance personnel need to check drains often to verify that water is present in the trap. Check them each time floors are cleaned. For traps that have dried out the solution is easy – pour water down the drain until the trap is full. While you’re at it, make sure that drains are clear of debris. If the pipe is cut and no longer used, cap the end for a permanent seal.
