I’m a real estate agent and commonly have to enter homes which have flea infestations. The crazy thing is most times I know about the problem ahead of time so I can try to protect myself. So far I’ve learned that really strong Deet will help keep them off me as will Permethrin. Do you offer these chemicals? I want to spray my lower legs or clothing before entering these flea infested homes so I don’t get bit. Is this what you would recommend?
