Ectoparasites in Mice

Pocket Pet · Mus musculus · typical adult weight 0.02–0.04 kg

6 cited drugs treat Ectoparasites in mice: Doramectin, Fipronil, Ivermectin, Moxidectin, Nitenpyram, Selamectin.

External parasites including fleas, ticks, mites, and lice. Isoxazolines, macrocyclic lactones, and pyrethroids each carry species-specific cautions (e.g. permethrin lethal in cats).

The overview above describes Ectoparasites across species; the citations below are the ExoticRx dose rules scoped to mice — a reference list, not new species-specific clinical guidance.
