What should I use to treat fleas under my house?
It has space to crawl, but not easily.
Our Outdoor Flea and Tick Kit has two products labeled to be used outdoors for fleas. You will mix the products together and spray them in the area. This treatment can be done every two weeks until you no longer see activity. You may also want to check for signs of rodents or other small animals that may be bringing the fleas into this area. See our Flea Pest Guide for more information about treating for fleas.
