Lol, every ant likes it warm when they're active (with the exception of super odd ones like winter ants).
Serafine, What I meant is that they like warmth for the duration of when they are active.
Is there storage hall near your place? These usually have tons of spiders.
I am not sure on the spray, and I may have exaggerated when saying no spiders, but very very little to if any spiders are here. If any ever do show in the house, they are to sly for me to get, or they are pretty freaky looking. The house is sprayed every week to 2 weeks. I see no spiders during winter, and during the spring you see them for like a couple days, then never again.
