“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.” – Hugo Hartnak, 1939
For Bobby Corrigan, pest management is a passion. Called upon for his expertise across the country, we are honored to include him in our conference.
Pests enter school buildings in one of two ways: they are transported in by students, staff, or delivery truck or they make their way in from the outside. The School IPM 2020: Where We’ve Been and What’s Next virtual conference will focus on the first mode, but we will also include information on the second with tips, and a tool, to help with exclusion – or keeping pests out of buildings. Dr. Bobby Corrigan, co-founder of the first Scientific Coalition on Pest Exclusion, will join us to discuss rodent vulnerable areas.
Lynn Braband has a favorite story about how he came to be employed by the New York State Integrated Pest Management Program. It occurred back in 1999 when Lynn’s experience with wildlife management brought him in contact with Director Jim Tette.
Our story is that it was a good day for IPM. Statewide, regionally, nationally, and even internationally, Lynn Braband made things happen through his determination, eagerness to learn and then share, his passion for the environment ,and his reputation as an all-around naturalist and reliable, genial collaborator. We have kudos to share–only a portion of the comments provided before and during Lynn’s VIRTUAL retirement party–but you can’t help but notice our photo header above with some typical Lynn shots. Much like other members of the Community IPM team, on-site scouting for pests was a big part of Lynn’s visits to school districts around the state.
Hang on while we run through SOME of Lynn’s organizational ties, collaborations, presentations and publications:
Starting with Lynn’s Masters in Wildlife Biology, Lynn worked in the wildlife control industry–including his own business–before joining the IPM Program. He is a member of The Wildlife Society, Sigma Xi, American Scientific Affiliation, National Pest Management Association, National Wildlife Control Operators Association, NYS Wildlife Management Association, and the NYS Wetlands Forum. Add to that, his dedicated service on the National School IPM Steering Committee, the International IPM Symposium Program Committee, the IPM Program Work Team, Rochester Healthy Home Coalition, the Statewide School Environmental Health Steering Committee, and foremost, his co-leadership of the Northeast School IPM Working Group.
As you might know, Lynn created and led NY’s Statewide School IPM Committee (above), but his impact on School IPM became much more than statewide. His retirement announcement prompted praise from collaborators across the nation.
Working with school staff around the state led him to applied research on reducing the risk of yellow jacket stings at schools, and keeping geese off playing fields.
Lynn has spoken on bird management, critters on golf courses, reducing bedbugs in childcare centers, and White Nose Syndrome on bats. I counted more than 150 publications, and over 50 public presentations just since 2012!
Two in-depth school surveys across NY were personally guided by Lynn–it was just a part of his deep commitment and relationship-building with building and property managers at individual schools, and with BOCES health and safety officers.
Trust us, or ask one of his colleagues. The incredible impact Lynn had on expanding IPM knowledge and practices was impressive, and we’ll be doing our best to fill in! As for missing Lynn himself, that’s going to take some getting used to. He might even have a story about that!
Brian Eshenaur, NYSIPM: “It was great to see Lynn’s dedication to get IPM principals utilized in school buildings. Though his leadership, he and colleagues throughout the Northeast have created resources to further school IPM goals in the region.”
“In the many years that I have worked with Lynn I’ve always been impressed with his “steadiness” (unlike me) and his work ethic. Lynn you have accomplished much and are an example of a wonderful public servant. I will miss learning from you.” Marc Lame, Indiana University.
Amara Dunn, NYSIPM: “Not only does Lynn do great IPM, but he is a genuinely kind colleague, and his sense of humor has enlivened many meetings.”
“I wish to take this opportunity to recognize Lynn Braband once more for his splendid support of school IPM efforts within his state and nationally. Lynn, you will be missed greatly; you have influenced, encouraged, educated and supported us all over the years.” Dawn Gouge, University of Arizona.
Jennifer Grant, NYSIPM: “Lynn’s steady commitment and patient persistence have been the underpinnings of his success in getting IPM implemented. That approach, along with his vast knowledge of wildlife biology and regulations, as well as his friendly demeanor, all combine to make it easy and enjoyable to cooperate with Lynn. Throughout his career, Lynn has also shown a strong interest in the ethics of science and pest management. He shares his musings with others, causing us all to think. Thanks for everything Lynn!”
“I want others in the IPM network to understand how instrumental Lynn’s work has been, what a legacy he leaves, and how much he will be missed upon retirement.” Lynn Rose, Pollution Prevention and EHS Consultant, Deerfield, Massachusetts.
Jody Gangloff-Kaufmann, NYSIPM: “What a pleasure and an honor to have worked with you for the past two decades, Lynn. I’ve learned a lot from you, most importantly to be more thoughtful and more careful with words. I’ll definitely miss your humor and I will never forget that Albany dinner when Rod Ferrentino sketched out his crimes on the paper tablecloth and had us crying with laughter. I wish you all the best in your retirement from IPM and future adventures.”
Kathy Murray, Maine Dept. of Agriculture: “Lynn has made a lot of good things happen over the past many years.”
Debra Marvin, NYSIPM: “Lynn’s knowledge of wildlife, including his expertise on birds, make him a great IPM facilitator. But his methodical way of approaching problems, and his gentle respect of others, his philosophy and humor make Lynn so admired by his peers, and (lucky for me) a great supervisor and co-worker.”
Joellen Lampman, NYSIPM: “I will miss my dinner time conversations with Lynn, many of which caused fellow diners to wish they had eaten somewhere else that night. But mostly I will miss his stories, his dry sense of humor, and his ability to organize different people with different interests around a common goal statewide, regionally, and even nationally.”
NYSIPM’s Matt Frye chose to honor Lynn in another way:

by Debra E. Marvin Comments Off on Timely School IPM Tip #3: Sanitation
This is the third and final post dedicated to tactics of school IPM most appropriate to the current situation of shuttered schools. (If your building is open to provide meals for at-home students, we applaud your efforts!)
Post #1 Scouting, Post #2 Exclusion. Sanitation is a third step in structural pest management, as it reduces pest habitat (food, water, shelter).
Sure to gain your attention, this photo (below) proves there’s been a lack of sanitation (and scouting, and exclusion!) But this scenario might well be the case in buildings left unattended during the Covid-19 closures. This may seem extreme, but sanitation isn’t just removing dead rodents, it’s keeping storage areas, kitchens and classrooms free of crumbs, condensed water, and recyclables.
Below is a (partial) look at our recommended Best Management Practices chart. We left off the Daily practices in favor of what can be done best during shutdown. Sanitation is more than just cleaning greasy stove tops. It’s getting to all those places we’d rather ignore, and reducing clutter and keeping food products in pest-proof containers.
The key factor is sanitation and reduction in habitat. Take care not to bring them in on packaging material (inspect incoming food). Clean up all spilled foods; don’t leave dirty dishes overnight; store all food in pest-resistant packaging; modify areas where pipes and utilities enter walls (caulk and screen all entrances); reduce moisture by improving plumbing and insulating pipes that routinely sweat. Empty garbage every day. Keep floor drains capped or full of water. Increase ventilation in moist areas. Baits are the most efficient and widely used form of control, but prevention is the least toxic method of control.
(Above) Mouse droppings are not just unsightly, they can cause allergic reactions and health issues, and can carry disease. Cockroaches exacerbate conditions like asthma. SANITATION also assists monitoring. If this area was cleaned last week, you can be sure the droppings are new.
(Above) Drain Fly Harborage: Clogged floor drains with decaying organic material provides breeding habitat for drain flies.
(above) This commercial storage area shows good spacing and pest-resistant storage. Keeping cardboard to a minimum, and providing space between items, and space below and behind the shelving makes for easier cleaning. (photo Dr. Matt Frye)
While pests like bedbugs are inactive waiting out school re-openings, the old standards like cockroaches and rodents can use quiet buildings to their advantage if habitat needs are met. Food, water and shelter are available in areas such as storage rooms, kitchens, boiler rooms and crawlspaces. If your building is currently unoccupied, pest activity can go unnoticed by staff, especially if there is a disruption in pest control operator visits.
OUR NUMBER ONE SUGGESTION NOW IS…SCOUTING. Building maintenance remains (at this time) essential work. Just like in the summer months, buildings without students allow much great opportunity for extensive scouting and cleaning.
LOOK FOR PESTS, PEST ACTIVITY and PEST ENTRY POINTS. The partial inspection list below notes areas that may not be addressed daily during the school year. Now is the time to move large pieces of kitchen equipment in buildings no longer providing meals.
Rat, cockroach, and mouse droppings. Can you identify? (cockroach on the right)
“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.

by Mary M. Woodsen Comments Off on 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
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.

by Matt Frye Comments Off on 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.
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 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, 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.
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 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.

by Matt Frye Comments Off on If you’re not monitoring, you’re not performing IPM.
Why? To start, let’s consider the distinction between an inspection and monitoring. An inspection is a view of pest activity at that moment in time. But what if pests are only active at night? Or on weekends when the building is quiet? Thus, monitoring is a record of pest activity in the times that you are not present.
Integrated Pest Management, or IPM, is a decision making process that uses information about pest populations to decide how to manage them. Monitoring is a critical step in IPM programs that offers valuable insights:
1. Species Identification: insect monitors intercept pests, allowing a trained professional to identify them. In turn, identification provides information about preferred harborage, food and water sources.
2. Early Detection: monitors can intercept pests that are present at low levels, and can help identify a problem before it gets out of hand.
3. Directionality: monitors can provide information about pest directionality: where are they coming from [harborage] and where they are going [food locations]. Monitors might also provide clues about non-obvious pathways, such as overhead areas (Figure 1).
Fig. 1. This firebrat likely fell onto the monitor from above.
4. Age of Population: rodent bait stations can contain informative evidence (Figure 2). Are droppings all one size, or are they mixed sizes, suggesting the presence of different age groups? Are droppings black, meaning that they are visiting the station for the first time, or are some droppings the color of the bait, suggesting multiple feedings?
Fig. 2. Mixed large and small droppings suggest adult and juvenile feeding; mostly black droppings suggest this is the rodents first feeding.
Parasitoids, predators and secondary pests can also tell you about the age of the infestation (Figure 3). Ensign wasps are egg-case parasitoids of American cockroaches. Their presence suggests that the cockroaches are actively reproducing nearby, whereas secondary pests may indicate the presence of old bait or pest carcasses.
Fig. 3. An Ensign wasp (egg-case parasitoid, 1), adult and juvenile (2) American cockroaches, and a spider beetle.
5. Proximity to Harborage: juvenile pests, including rodents and cockroaches, stay close the harborage. Intercepting them on monitors can narrow your search to nearby areas for identifying the harborage (Figure 4).
6. Management Efforts: some monitors might contain evidence about recent control efforts (Figure 4). Finding German cockroaches with crinkled wings is a sign that they have been treated with an insect growth regulator. But what if you didn’t apply this kind of product? Perhaps the cockroaches are coming from a neighboring area.
Fig. 4. Nymph (1) and adult (2) German cockroaches on an insect monitor. The arrow indicates the location of crinkled wings from treatment with an insect growth regulator.
Effective monitoring programs provide good coverage of pest vulnerable areas. The location of monitoring devices are recorded on a facility map, and a pest catch log records the number of pests caught on each monitor. These specifications allow the pest professional to collect enough information to determine if a treatment is needed, where to focus efforts and what treatment should be applied.

Where the links will take you:
Some large stinging wasps eat crop pests; others help pollinate them. Some do both.
Yes, different researchers say different things. Just know that cockroaches can survive without food for a couple of weeks and maybe much longer. (At need, “food” could include wallpaper paste, envelope glue, and more.)
“For an aphid, a raindrop is something like what a refrigerator would be like falling on us,” said researcher Jeremy McNeil, an entomologist and chemical ecologist at the University of Western Ontario in Canada.
Fleas can live a long time inside the cocoon they pupated in — until they sense a host nearby.
Follow the link to a fun, one-minute video of a fat mouse scrambling through a tiny hole.
Their name (they dig mines, as it were) gives them away — but you’d be surprised at how many different sorts of insects have larvae that burrow through something as thin as a leaf.

by Matt Frye Comments Off on Baiting for Mice, Rats? Try String!
Peanut butter is a staple in managing mice and rats, especially in residential settings. It’s easy to apply to traps, it stays fresh for several days — and a jar of peanut butter has a long shelf life. But peanut butter isn’t always your best bet. Because sometimes that peanut butter is a magnet for other pests — think cockroaches and ants. Besides, a large rodent population might have a wide range of food preferences. And for some, peanut butter might not be at the top of the list.
For those situations, here’s a trick that could help — bait those traps with string! String? Here’s why:
String tied to the paddle of a snap trap is a baiting technique that doesn’t feed other pests.
Females can give birth to six to eight litters of pups throughout the year, though they breed more often when it’s warm. They work hard at building nests for their young, and among their favorite nesting materials is string. So just tie a short piece string or dental floss tightly to the paddle of a snap trap and there’s your bait. Be sure to loop your string closely around the base of the paddle. And this is one bait that’ll never spoil.
