We are noticing more ants coming into the house and are considering getting someone out to spray the outside of the house, or whatever else you would do to prevent ants from coming in.

I'm sure people here must have some experience with this. Is it safe to spray outside with two snakes inside the house? If they suggest treatment inside the house, is there anything we should do the keep the snakes safe? Any precautions we should take or certain chemical/pesticides to avoid using? Housing the animals at a friend/family members house is probably out of the question.

I did try a search which came up with a few instances of people having their apartments/houses bombed for bugs, but I couldn't find much on standard outside treatments/baseboard spraying.
