Is here a reasonably priced exterminator in Waxhaw who can rid my upstairs vent of large brown bees? I cant see them close enough to determine what kind they are. They are about 22 feet up going in and out of my upstairs bathroom's vent fan exterior opening. The vent cover of course needs to be replaced. Recommendations welcome! Neither my husband nor I will attempt to climb a ladder that tall, especially with a swarm of bees!! Thanks!
