Frequently Asked Questions

What is flea dirt?

Flea dirt is essentially flea feces, which is dried blood that fleas excrete after feeding on your pet. It looks like tiny black or reddish-brown specks and is usually found on your pet’s skin, bedding, and other areas where your pet frequents.

How quickly can a flea infestation spread?

Flea infestations can spread quickly due to the fast reproduction rate of fleas. A single female flea can lay up to 50 eggs per day, and these eggs can hatch into larvae within a week.

Flea allergy dermatitis is a skin condition caused by an allergic reaction to flea saliva. It causes intense itching and irritation in pets, leading to scratching, hair loss, and skin infections.

Can fleas live on humans?
