I tried desperately to use the natural repellants for years. I did not find anything that would work on my dogs. Last year is the first year that we had any luck with controlling them on the pets, we use PetAmourPlus from Wal-Mart and the best for the house/RV that I could suggest that gave us success is the Enforcer brand powders and/or sprays: https://www.amazon.com/s/ref=nb_sb_...EESI4WO&rh=n:2619533011,k:enforcer+flea+spray I also used these which did help and let me know when and where the problem was intense: https://www.amazon.com/SpringStar-E...TF8&qid=1496405739&sr=1-4&keywords=flea+traps The traps also catch no see-ums, other gnats, some other crawly things. I do not like using these products, but nothing else worked. We live in a humid environment. In AZ, we had NO problem with fleas, I should have brought home a couple of lizards!
