Mites
These pests are outside the authority of the Vector Control Program. We offer educational information but do not control or regulate these pests.
Most mites are not a public health threat, but some can cause discomfort or harm to animals or humans by their feeding behavior. Some burrow into the skin of a host which can lead to skin irritation. Others can transmit diseases to humans; however, this is rare.
Mites can be found in almost all habitats and play different roles in each. Some mites feed on plants and organic matter, while others are predators or parasites.
Prevention and control
Many different repellents can be used to keep mites from attacking humans. Some mosquito repellents containing DEET can also be used to repel mites. A vacuum cleaner will collect many mites, but be sure to immediately remove the vacuum bag and seal it in a plastic bag for disposal.
Chicken mites
Feed on poultry, pigeons, sparrows, and other birds. When they have not eaten, they are white, but after a blood meal they turn bright red. The females lay their eggs in cracks and crevices inside poultry houses or in bird nests. Chicken mites hide in dark places during the day and look for a blood meal at night.
- Apply acaricide spray to cracks and crevices inside of buildings housing poultry or other birds
- Remove bird nests from around home
- Use screens or netting so birds cannot enter eaves or attics
Dust mites
Dust mites can be found in house dust all over the world but are more common in areas with high humidity levels. They live in bedding, couches, carpet, stuffed toys, and clothing. They feed on the dead skin that falls off humans and animals. Some people are allergic to dust mites, but most are not.
- Vacuum mattresses and floor weekly
- Put stuffed toys in dryer weekly
- Wash bedding and clothing weekly
- Encase mattress if dust mite numbers are high or if you are allergic
- Lower humidity levels in the home with a de-humidifier
Scabies or itch mite
These mites tunnel into the skin, especially on the hands and wrists, causing sores that burst and turn into scabs. The intense itching is known as "scabies." Scratching can cause bleeding and infection. Most often they are acquired by direct contact with an infected person, not an animal. For diagnosis and treatment of scabies, dermatosis, dermatitis, and other skin conditions, contact your doctor.
