Paper Wasps in Homes
small crevices near the roofline when searching for potential overwintering spots. Once
inside, paper wasps often hide in wall voids or inside warm attics. There, they enter a
state of diapause, suspending their development throughout the coldest months.
This means that homeowners most likely won’t see them until spring – unless there’s an
unusual period of warmer weather, during which time the wasps become active again
and look for an escape route leading back outside to start a new nest. At that point, the
wasps may make their way into the main living areas of the home, where they are seen
by the people who are living inside.
Paper Wasp Prevention
throughout the year – is to identify and seal all openings that lead to the outside of the
home. The National Pest Management Association (NPMA) recommends using a
silicone-based caulk, steel wool, or a combination of both to fill cracks and larger holes
in the home’s foundation.
Homeowners should pay special attention to porch ceilings, around roof eaves, soffits, attic rafters, windows and doorframes, as these are places where paper wasps congregate. It’s also a good idea to work with a licensed pest control professional to conduct an outside preventive treatment before the cool weather rolls in.
Calling a Professional
Sometimes it is easier to call a professional. Particularly if the problem is ongoing and the infestation has become large, or if the products are only authorized for use by certified professionals.
