There is no recommendation by the manufacturer on the product label for Martin's Flee Trigger Spray regarding bathing times. Generally you would want to wait at least 24-48 hours after application to bathe you animal. This gives the product time to dry completely and set.
Martin's Flee Plus IGR Trigger Spray is only for use on Dogs, Cats, Puppies and Kittens over 8 weeks of age as directed on the product label, it would not be used to treat homes for fleas.
For fleas inside we would recommend our Indoor Flea and Tick kit. We also have a great guide here that explains the most effective treatment.
