Paper wasp stings are painful and can cause allergic reaction to those who are hypersensitive to insect bites and stings. Many think that these wasps diminish during the winter, but unfortunately, they actually tend to stick around all season.
Most paper wasps die at the start of autumn, but female wasps who are to be the queen mother to a new colony start looking for a protective shelter. You can spot them inside your home during the cold winter. They sneak through tiny holes near the roof-line, infiltrate your home, and hide in wall gaps and inside warm attics.
In order to prevent wasps from invading your home, look for any openings that can potentially serve as an entry point for these insects. Using steel wool and silicone based caulk, seal all cracks and gaps. Windows and door frames, attic rafters, porch ceilings, and around the roof eaves are the usual sites where they gather. Those are great spots to check.
These insects are more likely indolent and inactive during cold temperatures so its a perfect time to remove them from your house. However, it is still important to seek the help of a pest control professional for safe removal, especially when you are dealing with a larger population.
