How to Get Rid of Box Elder Bugs

What are all of these tiny black and orange bugs doing on the side of my house and where did they come from? What can I do to get rid of them?

The first thing to consider when dealing with Box Elder bugs is their purpose in life. These bugs are attracted to the female Box Elder tree. You may not even have this type of tree in your yard, but if there is one nearby, you may find lots of these bugs sunning themselves on the side of the house or exploring the rooms inside. All they really want to do is eat, reproduce, and bask in the warm sun, (don't we all?) but when the sun goes down, they search for warmer accommodations, usually in cracks, under mulch and pine needles, and inside homes. As with other types of common bugs, you may decide at first to just ignore the problem, but with these critters, that would be a bad mistake. While they do not pose any health threat to humans that I'm aware of, nor do they bite, they do multiply very quickly. If a few wander into your home and are left unattended, they will make themselves very welcome and invite their friends.

If you notice these bugs hanging around, be sure to check inside all of the rooms in your house for cracks and crevices where they may enter unnoticed. Pay particular attention to windows on the eastern side of your home, especially old wooden ones that may not be weather-tight. If the Box Elder bug has paid you a visit, you will probably notice some weird orange spots that will scrub off painted surfaces with soap and water. If the bugs find your accommodations particularly comfortable, you may also notice tiny clusters of red eggs stuck here and there. Be sure to remove your blinds and look inside the box that holds the mechanism for raising and lowering them. They seem to enjoy hiding in there.

Use a wet paper towel with a little soap to remove the orange trail and any eggs that you may find. You may either vacuum up live adult Box Elder bugs or grab them in a paper towel and crush them, but be sure not to step on them or crush them onto a carpeted surface, as they tend to leave a red spot that stinks and is hard to remove. It is preferable not to do battle with these bugs inside your home. Don't bother using insect sprays to try to prevent them. It will not work unless applied directly to the bug. Your best bet is to find their colonies outdoors while the bugs are still too young to fly and destroy them before they have the chance to travel too far. Insecticide, like Ortho Max works when sprayed directly onto the bugs, but so does soapy water. Using detergent and water is the cheaper alternative and will be less harmful when used in areas where pets have access.

Don't be discouraged if it takes a while to get rid of these pests. Just be sure to keep an eye on them and kill them when you find them outdoors. Keep your home sealed tight and the impact from the Box Elder bug's visit will be minimal.
