Can chigger mites infest pets?
Can chigger mites infest pets?
Yes, chigger mites can infest pets. When cats or dogs play or walk in grassy areas, shrublands, or woods, chigger larvae (only pinhead-sized) crawl from the tips of grass blades onto the pet and attach to thin-skinned areas to feed.
Signs of chigger infestation in pets
- Frequent scratching or biting at certain body parts, especially ears, belly, inner thighs, and between toes.
- Small red spots or papules on the skin; sometimes tiny red mites can be seen attached.
- In severe cases, pets become restless, affecting appetite and sleep.
How pets bring chiggers into the home
- Chigger larvae climb onto pets when they are active in grassy areas outdoors.
- After returning home, some chigger larvae drop off pets onto carpets, sofas, and pet bedding.
- Chigger larvae in the environment look for new hosts and may crawl onto humans to bite.
How to protect pets and family
- After outdoor activities, use a fine-toothed comb to groom pets' fur, especially checking inner ears, belly, and between toes.
- Regularly apply pet-specific tick/mite preventives (spot-ons or sprays) as recommended by a veterinarian.
- Frequently vacuum and wash pet bedding, sofas, and carpets where pets stay.
- Spray the environment around pet bedding with permethrin-containing household insecticide (do not spray directly on pets).
- If chiggers are found on pets, consult a veterinarian; do not use household insecticides on pets.
Important notes
Chiggers do not stay on pets long-term; larvae drop off after feeding. However, their bites cause itching and discomfort, and they may crawl onto humans, so protection and inspection are still necessary.
