For inside, I use a product called Tempo SC. I started using it when we helped run an RV park in Idaho. We used it in the food prep. area and have been told it is safe for people and pets after it dries. I now use it inside the house and the RV. It is very expensive (about $40 for 8 oz. but it is mixed 16 to 1 with water and sprayed on) and you still have to be careful with it. I got it at a farmer's Co-op.
