There is boxelder control that can be bought in the market, and this may be your best option than most residual insecticides. Read labels first, so you’ll know it is especially intended for boxelder bugs and not other bugs and pests.

As always, the best way to keep them away is by inspecting where they are getting in. Cracks, crevices, gaps, and holes are mostly the way they get inside. Repair these holes and damages to your window to remove any entry points.


These insects will find a warm shelter where they can hibernate during the winter. Queen wasps will mostly survive as they hide in crevices or even in your attic. The wasp colonies are sure to die during the winter months because they cannot get any food and will die because of starvation.

Queen wasps are mostly taken care of by the colony, so they will stay alive to lay their eggs.

You need not worry about wasps stinging you during the winter cause the queen will mostly sleep during the winter while the colony will not be aggressive and would most probably be holding on to life because of hunger. But it is another case during summer or spring.

The types of wasps include yellowjackets, black hornets, as well as paper wasps. What you should worry about are black hornets and yellow jackets because they are highly aggressive, but it is highly likely they will die naturally during the winter as well.

Contact a professional for help once you notice a nest around your home and do not remove it yourself as their sting can be dangerous, most especially if you have a high allergic reaction to its sting.

Make sure that your windows and doors are all closed, and there are no gaps or cracks. A fly screen will work also, as long as there are no holes in it.

Although cockroaches can survive outdoors or indoors, they will likely move indoors to find warmth during the winter. You can find them in your crawl spaces, basements, and floor drains, or where there is moisture or water to survive. Most of the cockroaches will find electric motors or heated offices a great place to board during the winter and even the whole year-round.
