Yes, Fendona CS Controlled Release Insecticide is labeled to safely be applied indoors as a crack and crevice spray. You will use 1-2 oz. per gallon of water.
We recommend keeping Fendona CS Controlled Release Insecticide treatments at least 25 feet from bodies of water to avoid runoff into the lake. Otherwise it would be good to use for spiders. You would not apply to all exterior surfaces. Per the product label for perimeter treatments: Treat a band of soil 6 to 10 feet wide around and adjacent to the building. Also treat the building foundation to a height of 2 to 3 feet where pests are active and may find entrance. Treat other insect entry points such as doors, windows; under siding, decks and eaves of structure. Application should be made in such a manner to limit dripping and runoff on structural surfaces and plants.
