Boxelder Bug Spray
When boxelder bug problems can best be avoided by implementing a spray program at first sign of the pests. Use an insecticide spray that can safely be applied to the exterior surfaces of the building. Broadcast and pin stream spray patterns will be needed to treat the outside surfaces of the structure thoroughly. Different types of insecticides are appropriate for this job. If you like details, go to the Choosing a Boxelder Bug Spray section of this article. You can also skip to the summary section if you prefer to skip the details.
Broadcast treatment should first be applied to the
obvious side of the home or building where the pest is most likely to
"light" or land. This is usually the warmest side of the
building and (in most cases) is isolated to that single side but do not be
surprised to find the bugs crawling on more than one side of the house.
Broadcast using a fan spray or cone shaped spray pattern. This will give
you the most thorough and efficient pattern.
There will be boxelder bugs that escape
your initial broadcast treatment of the exterior surfaces of your home. To
kill boxelders as they enter, a pin stream type spray pattern is
necessary. Use this pin stream spray to treat cracks, crevices, around
windows, vents, doors or any other possible entry point.
Indoor spray treatment is not always necessary but it a few of the invading bugs will die from such applications. The vast majority of bugs will be eliminated from your exterior treatment, killing them before they have a chance to enter. If you want to treat indoors for boxelder bugs, limit your spraying to baseboards and the seams or cracks around window and door frames or other areas such as screened porches or enclosed patios. Do not broadcast the interior walls of your home with an insecticide spray.
Choosing Boxelder Bug Spray Products
There are several insecticide sprays that can be used in the control of
boxelder bugs and the choices can seem a bit confusing. This portion of
the boxelder bug spray section should make selecting the correct product for
your situation easier.
Before choosing a product (or products) there are a few things to take into consideration, such as the severity of the problem, how long you have had the problem, the size of your home, the color of your home's exterior surfaces, vegetation surrounding or touching your home and any other possible pest control needs.
There are three types of insecticide formulations from which to choose:
An emulsifiable concentrate is simply a liquid concentrate. This
formulation is usually cheaper (per gallon mixed) than other types and it dries
to a clear finish.
Tempo WP is the most popular spray for boxelder bugs. This product has what we call a very broad label. All this means is that you may safely spray the insecticide in more areas than with many other insecticides. Tempo can be sprayed indoors, on exterior surfaces of homes and can also be used on plants, shrubs, trees and most bedding plants. You can purchase Tempo WP by itself or in a kit. Tempo Kits are designed for those who have bad or severe problems with boxelder bugs or invading lady bugs. Tempo Kit #1 includes all products needed for heavy infestations. Tempo Kit #2 contains the same as the first kit but without the Chapin pump sprayer. Choose kit #2 if you already own a good sprayer. Details such as products included in each kit as well as pricing and ordering information can be found on the Tempo Kit page.
If you do not need to treat shrubs, trees or flower beds that are very
close to or touching your home, Demon WP or Cynoff
WP are the best sprays to use for boxelder bug control. Both products
contain the same active ingredient (Cypermethrin)
but you do have options of container sizes. Demon WP is available in a 1
Lb. jar that makes 24 to 48 gallons of finished solution. This product is
also available in a pack that contains 4 water soluble bags of pre-measured
concentrate. A pack of Demon WP will make 2 to 4 gallons of finished spray
If your targeted outdoor areas are high and you are not concerned with
spraying shrubs or ornamental plants for bugs, you should use either Demon
EC or Cynoff EC. Both of these products
contain Cypermethrin and both can be applied using a hose end type of
sprayer. By taking advantage of your water pressure, you can use a hose
end sprayer to reach as high as necessary on taller or multi-story homes.
Use Tempo SC or Tempo WP
if you need to spray shrubs or delicate plants while spraying your home.
If you need a good sprayer or if you have a stubborn, reoccurring, heavy
infestation, choose Tempo Kit #1 or Tempo Kit #2. Go to the
