Box Elders
Box elder bugs have black bodies marked with red lines on their thorax and sides. The biggest they grow is about 11 to 14 mm long, they have two antennas, and their flat red wings give them the ability to fly.
Box elder bugs usually make their nests in maple and ash trees during the warm weather and seek shelter during the winter. Most of these pests get indoors through cracks and holes of your home. While indoors, they won’t intentionally damage anything, however, their droppings do leave stains on house items. Outdoors, they will feed on trees, sometimes causing damage.
The best way to reduce these bugs around your home is to get rid of any host trees. If they have already infested your area and you want to get rid of them, we recommend contacting a pest technician who can create a custom treatment to eliminate them.
Signs of an Infestation
The most obvious sign of a box elder bug infestation is seeing a large number of these pests around. They are most often found during the fall on the side of buildings where the sun shines most. If they make their way into homes, they will most likely infest storage sheds and garages. They gravitate towards homes that have more sunlight beaming in and will usually be found in homes during the winter to stay warm.
When they are indoors, they can damage household items by staining them with their excrement. Outdoors, box elder bugs damage maple, plum, and cherry trees, as this is what they feed on. If you have an infestation, we recommend you contact a pest professional to get rid of them. You also want to be sure to remove unnecessary clutter and seal any holes in the walls of your home.
