Expert Response
Check the exterior of the window for any gaps or cracks. Seal or caulk them to prevent the box elders from moving between outdoors and the home.
When we see increases in daylength and days with warmer temperatures, box elders may gather in large numbers. The good news about them is they cause no damage to the home and do not bite.
