In the last week we've found a couple of wasps in the kids bedroom. Given the time of year I thought they had long died out at this stage, so I'm a bit concerned as to where they've come in. Do I take it that there is definitely a wasps nest somewhere close to the bedroom? If so do we need an exterminator or can you get some sort of home remedy to kill any remaining ones (if there are any). Obviously my biggest concern is making sure the kids are ok, so I don't want to take any chances. Anybody come across this before in the middle of winter?
