The Question
“Dear Dr. Paola,
I have a foster cat, Catsby, with serious environmental and food allergies. Since he’s allergic to dust mites he gets a weekly bath with a hypoallergenic shampoo. (Plus HEPA filters, frequent bedding changes, steam mopping, etc.) Someone recommended monthly treatment with Revolution because it would help with any dust mites in the environment. Is that true? I hate to put chemicals on his skin unless they really would help significantly. Thanks, Dr. Paola”

Quick Info about Catsby
Hi Kitty,
Thank you for your dedication to Catsby’s care while he finds a forever home! While Revolution (selamectin) is effective against many parasites like fleas, ear mites, and sarcoptic mange mites, it does not work on dust mites. Dust mites, such as Dermatophagoides farinae and Dermatophagoides pteronyssinus, live in the environment, feeding on household members’ skin flakes and other organic debris. Since they don’t live on or feed from pets, they’re not exposed to selamectin, which primarily targets parasites that live in and interact directly with treated animals.
I need to congratulate you, you’re already doing an excellent job managing Catsby’s dust mite allergies with HEPA filters, frequent bedding changes, steam mopping, and hypoallergenic baths. These steps are the most effective for controlling dust mites and minimizing allergens. Adding Revolution is unlikely to provide additional help with dust mites, so I understand your hesitation about applying chemicals unnecessarily. Please never take treatment recommendations by “someone” unless they are a vet who has an established doctor-patient relationship with your cat.
