Talstar P is labeled for the treatment of fleas outdoors only. It can be mixed with Archer IGR. They can be tank mixed at one ounce for each product to one gallon of water per 1,000 sq ft. It can only be applied to indoor cracks and crevices. Fleas will be on the open floor surfaces so it is important to apply a product to those surfaces indoors for eradication. We do carry a Outdoor/Indoor Flea Kit. Please take a few moments to review our treatment article How to Get Rid of Fleas.
