Bats, like spiders, are also pest control partners, but they can be a nuisance with the smell of bat guano, and even somewhat dangerous if they’ve become a tenant in your residence. ATCO provides an exclusionary service where we seal the area or the areas leading up their nest using a bat cone. They come out of the cone, but then when they return, they can’t get back in. We leave that up for a period of time and then we remove the cone and seal the opening. We are prohibited from performing this service during bats’ maternity period from June 1 to August 15. Bats are very beneficial out in the landscape, where they consume enormous amounts of mosquitoes and other insects, but you don’t want to encourage or allow them to come inside.
