Call the company and ask them or the workers when they come. Depending on the type of chemicals they're using and how strong the fumes are you may not have to move them or even leave the house. Management had our complex sprayed and they went through every apartment, when they came I told them about my reptiles. What they were using wasn't safe for reptiles so they just sprayed all the areas where I don't keep mine like the kitchen, cabinets in the bathroom things like that.
