These bugs are most problematic during the late spring and summer when elm seeds are abundant. They seek shelter indoors during hot weather and may enter homes through small cracks and gaps.
Elm seed bugs are small (about 1/3 of an inch long) and can easily enter homes through tiny openings around windows, doors, and other entry points. Proper sealing and maintenance of entry points are essential to prevent infestations.
Elm seed bugs can be resistant to many common insecticides, making it challenging to control them without professional pest management services. Integrated pest management strategies, including exclusion and habitat modification, are often more effective.
