Parasites come in many sizes, shapes and levels of "severity" for our pets. This collection of parasites are those commonly found on dogs and other species, sometimes affecting humans (called a zoonotic disease).
Cheyletiella are mites that live on the skin, causing irritation, dandruff, and itchiness. A distinguishing feature of this mite species are the large, claw-like mouth parts. These mites can be found quite commonly on cats, dogs and rabbits, and other species. Though humans are not a natural host for this parasite, Cheyletiella mites can happily live on humans for a while, causing an itchy rash.
A Cuterebra parasite is an opportunistic parasite found under the skin of small mammals. This parasite is the larval stage of the Cuterebra fly, who uses animal hosts to complete its life cycle. Learn more about this parasite, most commonly seen in summer and fall, in this FAQ.
3. Ear Mites
Ear mites are tiny parasites that live out their life cycle mostly inside the ear canal. They are quite common, and can cause severe irritation and itchiness of the ears.
The most common ear mite of cats and dogs is Otodectes cynotis, and therefore an infestation with ear mites is sometimes called "otodectic mange."

The answer is that there is no single method or insecticide that will completely eradicate (or at least control) a flea problem. The flea life cycle is fairly complex, and understanding the various stages will make it easier to get rid of them.
