This stink bug would appreciate a free pass into your home (or for that matter, your office). Learn how to keep it out.
After a few splendid years of low stink bug populations, we find ourselves in the midst of an epic invasion. In the past few weeks, I have captured dozens of brown marmorated stink bugs (aka BMSB), which fly from surrounding trees and perform a smack-landing onto my screen windows.
I do my best to capture the BMSB I see with a cup of soapy water. Simply place the cup under the bug and put your other hand over the bug. As a defensive mechanism, stink bugs will drop into the cup, requiring no physical contact on your part. Just toss them out the door or off your balcony. Or you could wrap it in a tissue and squish it; the tissue will keep stinky oils off your hands and out of the air. (As your final coup, you could drop the tissue in your compost bucket.) Both methods save a five-gallon flush down the toilet — really, you don’t ever have to flush stink bugs.
For the stink bugs I don’t catch, I try to keep them out of my house by making sure that my windows screens aren’t torn, there are no gaps around my windows and doors (they fit snugly into the frame), vents are screened or louvered, and window air conditioning units are removed before autumn — all key preventive tactics and core to good IPM. But I recently observed a new entry point on windows that I hadn’t considered before: the window weep hole.
Holes in screens are an invitation to stink bugs and other pests.
This window weep is missing its cover.
Weep holes are design features that allow water to escape from a structure, whether it’s a window, sliding door or a brick building. Weep holes must remain open for water to drain even as they exclude pests. For example, weep holes in brick can be covered with specifically designed screen materials or filled with pest exclusion products such as Xcluder Fill Fabric*. Newer windows have weep hole covers that function like one-way-doors: they open to drain water but are otherwise closed. Sometimes — as in the case of my windows — these break off, leaving an excellent entry point for pests such as BMSB. Once bugs enter the weep hole, they can climb up through gaps into the window track and into the space between the screen and the windowpane. When you open the window, well — you just gave them a free pass into your home.
Weep hole covers are available for purchase at a number of outlets, but you must buy the right cover to fit the dimensions of your window. Because of the variability in window weep hole sizes, pest professionals and maintenance personal who manage offices and apartment buildings might choose to use Xcluder Fill Fabric that can be cut to the proper size, providing both pest exclusion and water drainage.

These days if you live near anything green — a suburban development, however humble or high-class; a neighborhood park where shrubs and meadow flowers grow — best you’d read up on ticks, be they black-legged ticks (aka deer ticks) or lone-star ticks (so named for the silvery white dot on the female’s back). While you’re at it, read up on Lyme disease and its suite of co-infections, some nastier even than Lyme.
And know this: no magic spray or treatment will eliminate ticks.
Wear tick-killing clothing. Buy over-the-counter permethrin spray and spray it on your clothing and gear. Used according to the label, permethrin binds to the material and can kill ticks, mosquitoes and other pests following a lethal exposure. Do-it-yourself treatments can remain effective for up to seven washes. Also consider buying pretreated cloths or sending your outdoor socks, pants, and shirts for professional treatments. These can be protected for up to 70 washes.
Follow label instructions for do-it-yourself clothing treatments.
Ticks wait for a passing host on vegetation or in leaf litter. Staying on trails can reduce your exposure to ticks.
Recognize and avoid tick habitat.Tick species differ in where they prefer to hang out. The blacklegged tick (transmits Lyme disease) is found at adult knee-height and below in wooded or brushy areas. When hiking, stay on the trail and away from these areas. If you’ll be in tick habitat, take precautions by wearing long pants tucked into your socks and a light-colored shirt tucked into pants. These steps make it more difficult for ticks to get to your skin. If you’ve treated your clothing with permethrin, this can also increase the exposure of the ticks to the acaracide — the tick-killing substance.
Steer clear of hitchhikers.
Isolate exposed items in large, zippered plastic bags to avoid bringing ticks indoors.
Ticks can be carried on clothing or gear that you used outdoors — gear that you haven’t used permethrin or a repellent on. True, ticks don’t survive long in most homes because of low humidity, but still — you’re safest if you change your clothes and place exposed items in a large, zippered plastic bag in an entryway. Put them in a clothes dryer and run on high heat for 20 minutes. The tumbling action of the dryer and the high heat kill ticks and similar critters. [Note: don’t wash clothes first. Even the hottest cycle might not kill ticks, and it increases the drying time needed.]
Check for ticks. Taking all these steps doesn’t mean you will avoid ticks 100% of the time. Perform daily tick checks even if you haven’t been outdoors in a day or so. Get to know the marks on your skin and recognize new ones. New marks that, if you touch them, just happen to have legs.
Remove ticks safely. Only one method has been officially evaluated for its ability to safely remove ticks — using sharp tweezers, grab a tick as close to the skin as possible and gently pull up. Other methods could increase the risk of acquiring a tick-borne disease. To learn more, see our post “It’s tick season. Put away the matches.”
Protect your pets.
Grooming after outdoor activity with a fine-toothed brush can remove ticks in pet fur.
Just like people, pets can encounter ticks and acquire tick-borne disease. If your pet goes outdoors, it should have some protection against ticks. TickEncounter describes some of the options available for your pets, including oral and spot-on medications as well as collars. Speak to your veterinarian about the best option for protecting your pet against tick bites. Regular grooming with a fine-tooth comb after being outdoors can help to remove ticks that have not attached to your pet’s skin.
By now, you’ve heard of Lyme disease. If you’re reading this in the Northeast, chances are you’ve had Lyme disease or know someone that does. And perhaps you know that Lyme disease is a topic entrenched in scientific and political controversy in terms of accurate diagnosis, effective treatment, and access to insurance. Putting these larger issues aside for the moment, the intent of this post is to present data on Lyme disease and help people to better understand the risks.
What: Lyme disease is a series of symptoms that occur when our body is infected with a bacterium called Borrelia burgdorferi. In the Northeast, the only way that people and animals become infected with Lyme is when they are bitten by a blacklegged tick – sometimes called the deer tick. The complex lifecycle of the tick and how they obtain and transmit pathogens is described by TickEncounter.
Boys aged 5-9 years old have the highest confirmed number of Lyme Disease cases (Source: CDC)
Who: Each year, approximately 30,000 cases of Lyme disease are reported to the CDC, making it the most commonly reported vector-borne disease in the US [a vector-borne disease is one transmitted through the bite of an organism such as a tick, mosquito, flea, etc.]. However, studies suggest that this number is only a fraction (about 10%) of the actual cases of Lyme disease in the US, putting the estimated number of cases between 300,000 and 400,000 each year. Based on this value, Lyme disease is the second most common infectious disease in the US, falling between two sexually transmitted diseases: Chlamydia (#1) and Gonorrhea (#3). Who is at the greatest risk of Lyme disease? Children! Especially boys aged 5 to 9 years old. Parents – check your children daily for ticks!!
Most cases of Lyme disease occur in the summer after being bitten by a spring-time nymph tick (Source: CDC)
When: Ticks can be active any day of the year when temperatures are above freezing. However, based on their lifecycle, the greatest risk of acquiring Lyme disease occurs during the spring months when nymph ticks are present, resulting in summer-time symptoms and doctor visits. Nymph ticks are about the size of a poppy seed, which makes them difficult to see. Check yourself daily for ticks, using your fingers to feel raised bumps and your eyes to notice new black marks.
It’s Invasive Species Awareness Week — now. Pay it heed. Invasive species, it turns out, are a huge deal in the US, in New York. Everywhere, in fact.
Coping with invasive insects, pathogens and the like have cost, in the US as a whole, upward of … OK, I’m hedging already. Is it $40 billion a year? $120 billion, maybe? The estimates vary widely.
What about global losses? Ahhhhh. Nailing those, especially vital ecosystem-regulating services, is where “difficult” morphs into “impossible,” for now and perhaps forever. It’s tricky, measuring something when it’s gone.
So what about the price here in New York? Unknown, though not for lack of trying.
Example: My admittedly quick-and-dirty search uncovered a 2005 report which noted that costs for eradicating Asian Long-horned beetle from New York City and Long Island had ranged between $13 and $40 million.
Killer beetle has distinctive markings. See something? Say something. Photo credit Kyle Ramirez.
Likewise in of 2005, New York spent about a half million dollars to control sea lampreys in lakes Ontario and Erie — with no end in sight.
More recently, in 2016, I learned that oak wilt — first discovered In New York in 2008 — has cost $500 grand to control. Some midwestern states spend over $1 million a year to control it. Pretty pricey if you ask me.
What helped here? Partly it’s the luck of the draw — oak wilt arrived decades ago, making inroads throughout the Midwest slowly but relentlessly. It can take time to recognize the true nature of a pathogen — or most any invasive pest. Then it’s a catch-up game to stay on top of it. If you can.
On the loose all over the Midwest — and now here. Photo courtesy Iowa State Plant Disease Clinic.
New York saw what had happened elsewhere and has aggressively surveyed (good IPM!) and eradicated infestations quickly while still small. But that $500 grand price tag? Yow.
Still, the economic costs of losing every (yes, every) oak would far greater.
Yet to come — what to if you find Asian long-horned beetle, oak wilt, and the like.

It’s summer; the goldenrods will be blooming soon, with bumble bees buzzing around them. Photo courtesy David Cappaert.
When we think about bees, we mostly think about honeybees … a European native brought here by the very first colonists. Now honeybees are struggling, hammered by a constellation of 20-plus diseases and parasites — not to mention a range of insecticides and fungicides.
About 450 species of wild bees also populate our fields and gardens. They have similar problems. And they’re losing habitat.
This is serious business: we depend on pollinators for at least one-third of our food supply. Altogether, these pollinators boost New York’s economy by $1.2 billion.
And consider all those other critters: flower flies and hover flies, wasps, butterflies and moths; even hummingbirds — they are legion, they work hard for their living; they help too.
NYSIPM funds educational projects like this. Photo courtesy Jen Stengle.
What to do? For starters, we can make all these helpers even more at home in our fields and gardens.
Indeed, it’s through bringing together everything IPM knows about host and pest biology and habitat; about pesticides and their EIQs; about habitat protection and biodiversity — these are the things we excel at, and these are what we’re putting into play now to find the answers we need.
Ah … answers. Such as?
Since protecting non-target organisms is core to IPM, we helped advise the governor’s Pollinator Task Force in crafting a Pollinator Protection Plan — itself informed by a national strategy to promote the health of all pollinators. And our flagship IPM Annual Conference highlighted an IPM problem-solution approach for the 100 participants: farmers, consultants, beekeepers (but of course), landscapers, researchers, policy makers, greenhouse growers, and more.
Check it out — not only because you care about your health and your food supply, but because you care about this beautiful world we live in.

We tend to default to bugs — to insects — when we think about pests. But plant diseases and weeds are pests too. And all threaten our fields and farms, our forests and streams, our homes and workplaces.
Pests provide no end of challenges — especially pests that come from afar. Among IPM’s strengths? Researching and crafting powerful ways to cope with them.
Coming up soon, our “Invasive Species in New York: Where We Are and What We Can Do” conference, held just north of Albany at Siena College. The date? July 13, 2017. Join us!

by Mary M. Woodsen Comments Off on Keep Off the Grass? IPM for Anyone With a Lawnmower
Now that spring has arrived and you’ve dusted off the lawn mower …
PUBLISHED ON MAY 3RD, 2017, CANTON, N.Y. | Courtesy Paul Hetzler, CCE St. Lawrence County
As a kid of about five, I became suspicious of lawns. In a rare moment of TV viewing, I had seen a public-service ad wherein a bundle of green leafy stuff thudded into an eerily vacant playground while a baritone voice boomed out something like “Grass. We think it’s bad for kids. Stay away from it.” My mom insisted this was “bad grass” which did not grow in our yard. However, she declined to elaborate, which fueled my mistrust. So I kept off the lawn a while.
These days, “bread” is no longer money, “mint” is just a flavor, and the pernicious leafy stuff mostly goes by other names. There is only one grass, and it is almost time to cut it again. Jargon may change, but things like paying taxes and mowing lawns don’t seem to.
To help you, or so they say, a bewildering array of lawn-care products have sprouted at big-box stores and garden centers. It’s easy to spend a lot of dough — I mean money — on fertilizers, weed killers, and seed. But it’s hard to make sense of which products are right for you.
Before you shop, a couple of thoughts to help sort things out.
Grass is not for everyone. Or everywhere. If an area does not get 4 or more hours of full sun daily from March through September, trying to grow grass there is a waste of time.
Steep slopes and high-traffic zones probably need something other than grass, too.

Comparison spells trouble. Well not literally, but it’s mighty unfair. Fashion models have airbrush artists and makeup consultants. Golf courses have full-time turf experts and a massive budget. With good information and a little work, we and our lawns can both look good, but let’s not compare with deep-pocketed pros.
Dr. Frank Rossi, a leading Cornell Turfgrass Science researcher, puts it this way:
“Chances are you can grow a pretty good lawn without using insecticides, fungicides, or herbicides. You may even be able to do it using little or no chemical fertilizer… Will your lawn look like a putting green? No… But if you arm yourself with an understanding of what grasses need to thrive, and commit to a long-term plan to meet those needs, you can grow a perfectly acceptable lawn…”
Get the dirt on your soil. If your grass looks bedraggled, fertilizer may not be the answer; in fact, early-season nitrogen can weaken grass and make lawns worse in the long run.
At the very least, get a soil pH test—a pH more acidic (lower) than 6.0, or more alkaline (higher) than 7.0 will hinder plants’ ability to absorb nutrients. The majority of samples I get at the office have pH values too high for healthy lawns, sometimes 100 or even 1,000 times too alkaline due to annual lime treatments. Lime is only good if it’s needed.
If it’s been over three years since the soil was tested, you might want to invest in a lab analysis. For under twenty bucks you can get nutrient levels with specific recommendations, plus pH and salt content. This last item may seem odd, but fertilizers, herbicides, wood ash and deicing agents are all sources of salt — which can damage soil structure, harm microbes, and aggravate water stress.
Only fertilize based on soil test results, and only use nitrogen in the fall.
Nature abhors a vacuum, which is why I keep mine hidden away indoors — no sense offending nature if you can avoid it. This hatred of emptiness means that if you don’t re-seed bare or weak spots in the lawn, Nature will fill it with whatever is handy — probably weeds.
Edging along the sidewalk or driveway may produce the look you want, but it also produces a lot of bare earth, so if you have a weed issue, especially crabgrass, breaking this habit will give you an edge on weed control.
Another type of vacuum is a close-cropped lawn. Not only does close mowing cause weak, stunted grass roots (and thus plants), it allows the sun full access to the soil. This gives weeds a tremendous advantage.
Have trouble with ground ivy? Put away the vacuum. Stop shaving the earth and start mowing the grass.
The most important thing you can give your lawn is more of its hair. Studies show that changing to a grass height of 3.5 inches leads to a vast improvement in lawn health. Leaving grass longer will greatly reduce weed pressure, lawn diseases, and fertilizer requirements. Perhaps the most dramatic change with longer grass is a lasting drop in weed population.
If you need to use herbicides to reduce weeds, follow the label instructions closely. Some broadleaf (selective) herbicides contain chemicals that could stress or injure trees. Pre-emergent herbicides inhibit weed germination, and are used for crabgrass control. Apply pre-emergent products around the time forsythia flowers are starting to drop.
Another tip is not to mow more than a third of the grass at a time. For example, to maintain a 3.5-inch turf height, mow before the grass gets over five inches high. Try to keep the blades sharp — it can help reduce disease, plus it looks nicer and saves on mower gas. And it almost goes without saying that grass clippings belong to the lawn, not the landfill. Leave the clippings—that’s your fertilizer.
White grubs — we have five species in northern NY — can become a problem if there are more than ten per square foot of lawn. Several nontoxic and low-toxicity treatments have come on the market in the past few years, but timing varies for all of them. Milky spore treatment is safe, but is not effective up north due to cool soils. You can also use beneficial nematodes to kill grubs.
There are many solid lawn-care resources out there, but always check the source, which should be from .edu or .gov sites. Cornell Senior Extension Associate Lori Brewer has assembled the work of many experts, including Dr. Rossi, into a comprehensive 47-page book entitled “Lawn Care,” which is free at http://hort.cornell.edu/turf/lawn-care.pdf
I think it will contribute to a better world if we teach our kids to stay grounded and let the grass get high.
These nematodes Hetzler mentions — beneficial organisms — are key to good IPM. In fact, good IPM embraces every concept Hetzler stands by. With IPM, prevention is always the best cure. And remember: even herbicides are a type of pesticide, because weeds are pests too. If you’ve ever spent a whole day weeding a not-that-big garden, you know that sometimes weeds are the most difficult contenders we face. — ed. MW.

by Mary M. Woodsen Comments Off on The Monarchs Are Coming, Ready or Not.
Gorgeous in flight and gloriously colored, monarch butterflies are the glimmering icon of wild nature. As an endangered species, they’re also iconic of all we have to lose in a changing world.
And now it’s begun — the remaining monarchs’ first leg of an epic, multigenerational voyage from overwintering sites in Mexico. But are they too early?
Getting here takes food, and plenty of it. For monarchs streaming up the eastern flyway to summer in our gardens and wildlands, you want flowering plants that offer generous helpings of nectar, the butterfly equivalent of a protein shake with all the essential nutrients it needs. But you also need more: you need the one plant that protects monarchs from the animals that might eat them.
Swamp milkweed. Likes moisture in but tolerates sandy, dry soils and part shade. Fragrant and long-blooming. Its protective steroids are among the most potent any milkweed species has to offer. (Offers nectar, too.) Photo: Tom Potterfield, Flickr Creative Commons.
As for the nectar plants? All of us — farmers, gardeners, golf courses and park superintendents — can help, each in our own way, with plantings of nectar-rich plants that attract beneficial insects. And beneficial insects are one of the mainstays of good IPM.
But it’s milkweed alone with its protective toxins that the monarch butterfly lays its eggs on; that its caterpillars feed on. So of course, gardeners and golf-course or park superintendents will want to plant milkweed too. Many species are stately, short-lived perennials bearing fragrant flowers. (Farmers, you might — or not — have options for happily letting milkweed grow.)
Butterfly weed. It’s gorgeous, no getting around it. Tops out at two feet; does fine in droughty soils. Too bad this milkweed’s protective steroids tend to be in short supply. Photo: Beautifulcatava, Flickr Creative Commons.
Now … for that “too early?” part.
As we speak, monarchs seem to be moving north earlier than usual, supported by strong tailwinds. Yes, they’re finding some nectar sources — dandelions, for instance. (If you must mow now, mow high. Which you should do anyway if you practice good IPM.) But according to some reports (citizen scientists with Annenberg Learner’s Journey North and ecologist Chris Helzer’s Prairie Ecologist posts via The Nature Conservancy), monarchs seem to be looking for milkweed — and not finding it.
As of April 21, “Journey North” sightings have come in from New Jersey, Pennsylvania, Ohio, Michigan, Ontario Canada … we’re surrounded!
Or if the butterflies find milkweed, it tends to be just a few inches high. Question is: can a six-inch-tall milkweed support six to eight larvae? Unknown.
A close look at the map and you know they’re on their way.
Good questions poised by a citizen scientist: can this milkweed plant grow fast enough to feed growing caterpillars?
Since scouting is another core tenet of IPM, be a good scout — and keep a sharp lookout for monarchs, milkweed, and monarch eggs. Three’s a charm!

by Mary M. Woodsen Comments Off on Earth Day IPM for birds and bees — and native plants that nourish them
We’re starting this post with a detour. But we have little choice. Before you go shopping around for landscape plants, you need to know the backstory.
Invasive plants, trees, shrubs, vines and flowers, many of them brought from afar because yes, they’re lovely in the landscape, have become a bit too much of a good thing. In part it’s because they didn’t evolve here. That could mean the critters — mostly insects or pathogens that co-evolved with them and helped keep them in check — don’t live here. Where that’s the case, there’s little here to naturally keep them in check.
OK, sumac berries aren’t all that tasty. But for migratory songbirds powering their way north, they offer needed nutrients. (Photo credit Mary Holland)
True, not all imported plants are invasive. But it’s all too easy to dig up a seedling or sucker from an invasive when you don’t know the extent of the problem. Which is partly why New York passed the Invasive Species Prevention Act in 2012.
Native plants, on the other hand, are less likely to get out of hand. Plus they can encourage biological control by attracting predatory or parasitoid insects — the good guys that prey on insect pests. And promoting these good guys is key to good IPM.
So with Earth Day in mind and planting season at hand, let’s note this threesome of invasive trees: angelica tree, sycamore maple, and Amur cork tree. These landscape trees are no longer for sale in New York. For a threesome of attractive natives that can fill their place — while helping the birds and bees — consider the merits of (drum roll) staghorn sumac, Juneberry, and white fringetree.
As we speak, migrating birds are stripping last year’s crop of staghorn sumac seeds, now mostly dry and withered but still nourishing, to power their northbound flight. Love birds? Your sumac planting will benefit robins, bluebirds, thrushes, catbirds, cardinals, chickadees, starlings, wild turkey, pileated woodpecker — and that’s just for starters. Soon its tiny yellowish flowers will attract bees and butterflies. Fiery autumn color. Drought resistant, and an excellent soil stabilizer on hillsides.
Juneberry isn’t your traditional hummingbird plant but welcoming even so. And first to flower means first to fruit — nourishment for many nesting songbirds. (Photo credit Hans. Thank you, Pixabay)
Juneberry (Amelanchier spp., with more common names than you can shake a stick at) is also an early bloomer that draws hummingbirds, bees, and butterflies. When its fruits ripen in early summer, robins, waxwings, cardinals, vireos, tanagers, and grosbeaks make a point of stopping by for a meal. You might too — the subtle flavor, shape, and color are reminiscent of blueberries. Grows well in full sun or part shade; adapts to wet or dry soils — but note soil must be acidic.
And then — raise your hand if you’ve seen our native witch hazel. This late bloomer is (metaphorically, that is) the golden chrysanthemum of the woods, daring to blossom when other trees have tucked in for a long winter’s nap. How to describe its flowers? Ribbonlike. Spidery. Kinky. Confetti-like — these all serve for a tree that’s the only show in town. But … if pollinators have tucked in too, how to play the pollination game? Turns out a native moth, the sallows, comes out on chilly nights — shivering its flight muscles and raising its body temperature upward of 50 degrees, then flying off search of food. And during a warm spell, bees will sup here too. Yes, this tree benefits birds and wildlife too, but more on that another time.
Witch hazel makes a lovely understory tree. Prefers part shade and moist but well-drained soil.
Common to all? They fit neatly under power lines.
And now a plug for IPM: it’s easy to talk about the birds and bees. Yet so many critters are on our side. Understandably we shudder when wasps and flies come to mind. But consider the scads of wasp and fly species that are on our side. Hey, plenty of wasps don’t even have stingers; they care only to lay their eggs within pest insects. Flies? Ever heard of flower flies? They do what their names suggests, while their larvae prey on aphids and thrips. And there’s scores more good guys in the family they belong to.
I love any excuse to come to New York — when it’s not February. — K. A. Applegate
Ahh, February. The Monday of months. Yet even with a foot of snow on the ground over most of New York, you can take steps now for a healthy lawn.
The Feb. 9 U.S. Drought Monitor shows 35% of the Northeast in a drought.
First, be grateful for the snow — and add more to your wish list. The Northeast Regional Climate Center notes that much of New York is still in a drought. We’ll check next week to see how the February 9 snowstorm affects the readings, but The New York City reservoir system was at 77.6% of capacity on February 8 compared to normal capacity of 87.8%. We still have a ways to go to make up the deficit.
Lawn Care features expertise from Cornell University Turfgrass research team. Vidoes, photo galleries, interactive images and concise directions make it quick and easy to understand how to cultivate a healthy lawn that is an attractive environmental asset.
Turfgrass Species and Variety Guidelines for NYS – If you want to get deeper into the science of seed selection, then this is the resource for you. Different types of turfgrass are adapted to different soil, light, and traffic conditions. Choosing the right type will help you maintain the best lawn with the least amount of inputs such as irrigation, fertilizer, and pesticides.
Cornell University turfgrass expert Dr. Frank Rossi narrates this short how-to video on sharpening your mower blade.
Third, the single most important lawn care practice you can undertake for a healthy lawn is proper mowing — and now is a great time to sharpen those blades. Why bother? Dull blades:
shred rather than cut grass
stress your lawn, making it …
more susceptible to insects, diseases, and drought
Fourth, the ongoing drought left many poorly or non-irrigated lawns a little thin. Overseeding helps fill in the bare spots. You don’t even need to wait until spring. Dormant overseeding over the next few weeks can help you get a head start on the season. Use the resources above to choose a drought-tolerant turfgrass type, so watch the forecast and try to get out ahead of the next snowstorm.
