Rat Fur Mites (Radfordia ensifera)

Rat fur mites, also known as Radfordia ensifera, are a common type of mite found on pet rats. These tiny creatures can cause your pet rat a great deal of itchiness and irritation. Unfortunately, they can be very difficult to diagnose without the help of a veterinarian.

The most common way to test for their presence is by doing a skin scraping or using adhesive tape to collect some cells from the rat’s fur.

Even if these tests do not show the presence of mites, it does not mean that they are not there. Specialized tests may be required to make a definitive diagnosis.

Ear Mange Mites (Notoedres muris)

Ear mange mites are a type of mite that live on rats. They are much less common than fur mites. Crusty, scabby ears, noses, tails, and even feet are symptoms.

These tiny mites tunnel into the skin. They can only be found on rats and cannot survive for very long off their host.

Tropical Rat Mites (Ornithonyssus bacoti)

Tropical rat mites are the least common type of mite found on pet rats. They are most commonly found in tropical and subtropical climates but also in temperate areas.

Along with rats, they bite people and other animals. They become apparent to the naked eye as they become engorged with blood. They typically have dark red, brown, or black skin.


Lice are less common than mites, but they can still infest rats. They can cause the rat to scratch themselves and lose fur. Rats usually don’t develop scabs when they have lice.

But you may be able to see them on the rat’s neck, shoulders, and back where it’s difficult for them to reach.

The eggs of the louse are very tiny and silvery in color. They attach themselves to the hair shafts close to the scalp. The adult lice feed on human blood, and their bites can cause an itchy rash.

How many legs do rodent mites have?

Rodent mites are a type of mite that specifically live on rats. They are parasites that feed off the blood of their hosts. Like ticks, they have four stages of development: egg, larva, nymph, and adult. The larva has six legs rather than eight, so be careful not to confuse them with ticks!

How to get rid of rat lice base?

You can take a few steps to get rid of rat lice. The first is removing the host animal and cleaning and sanitizing the area. The next step is to treat the surrounding area with a pesticide that is safe for indoors and formulated for mites.

Vacuuming visible mites or wiping them up with a damp cloth removes existing mites, but it is important to freeze vacuum bags to ensure that the mites are dead. Finally, they may enter your home if you do not control the rodent population.


Three types of mites can infest rats: fur, ear, and burrowing. Radfordia ensifera is a fur mite similar to the mites that infest mice. Rat mites’ symptoms include hair loss patches with possible skin ulceration or lesions.

In conclusion, take the steps mentioned above to eliminate mites in rats. If this mite causes the lesions, they will be reddened, crusty, and itchy. The bloodsucking mite known as Ornithonyssus Bacoti is known to drop off to hide in wood products, cracks, and crevices near or inside the rat’s cage.
