The products we carry are safe when used as directed, pets should be out of the area during treatments until dry. Treatments for fleas and spiders would be different. When dealing with fleas, we would recommend our Indoor Flea Kit. Here is a great video on how to use our Indoor Kit here. For spiders, spraying around the perimeter of the home and inside in cracks and crevices with something like Demand CS would be the best choice. We have a great video that shows where to spray for perimeter and interior spraying. Please click on the link below to see the video:
