Brown marmorated stink bug
Like Asian multicolored lady beetles and boxelder bugs, brown
marmorated stink bugs like to hibernate in our houses for the
winter. They do not eat fabric or furniture and are not known to
bite people or pets. They do cause concern when large numbers of
them congregate on the sunny sides of houses in the fall, looking
for a way in. They repeat this behavior in reverse in the spring (or
even a warm, sunny day in winter), congregating on interior walls,
looking for a way out. They emit an unpleasant odor when crushed or
disturbed (hence the name “stink bug”). Researchers believe there is
one generation of brown marmorated stink bugs a year in
Dealing with Stinkbugs
The best way to deal with all of these nuisance pests is to keep
them out of your house as much as possible. Screen all openings and
attic vents. Make sure your window screens do not have holes in them
and that the weather-stripping on doors fits snugly. Caulk all
cracks around window and door frames, openings where utility pipes
and wires enter your house and any other opening to the outdoors.
Use a pest spray?
You can reduce brown marmorated stink bug congregations outdoors
with sprays of synthetic pyrethroids, including the active
ingredients cyfluthrin, deltamethrin, lambda-cyhalothrin, sumithrin
or tralomethrin. A licensed structural pest control operator should
apply these products in the fall, just before insects begin to
congregate. Since many pesticides are broken down by exposure to
sunlight, the residual effect of such applications may not last more
than a week.
Do not spray these products inside your home. They will not prevent
insects from coming in through unsealed crevices. Also, even though
these products may kill many insects in wall voids, their decaying
bodies may attract carpet beetles that will damage wool fabrics,
grain products of all kinds, pet food, and many other food items.
Use a vacuum to remove brown marmorated stink bugs and change the
bag or empty the canister frequently.
