Boxelder Bugs can be a real nuisance and are identified as a occasional invader. They become quite numerous in the Spring and Summer, populations go off the scale. I have seen (millions) similar to False Chinch bugs especially in tall grass and weed areas. So the key in reducing the population is to keep grass mowed and weeds in check.
These bugs feed by sucking the juices out of the plants and therefore pose little risk to homeowners. Keeping doors and windows shut can keep the majority out but since they are little they often sneak by. The use of screens is extremely beneficial and is considered (IPM) Integrated Pest Management. Reduce and seal cracks, electrical outlets can be sealed with caulking and check the jtrim along the stucco edge of your home. You can also seal all holes on exterior and interior of the home.
Boxelder Bugs don’t bite, but since they have a piercing suck mouth part they could possibly puncture the skin. The ideal treatment is a barrier pest control treatment which will help to reduce numbers. They are also a prey of scorpions and spiders. So keeping those numbers down is essential in keeping your home bug free. As always please call ProBest Pest Management 480-831-9328 or 623-414-1076
