As warmer weather approaches, a small but bothersome mite could cause you some seasonal discomfort. Kansas State University entomologist Raymond Cloyd warns that chiggers, which become active in April, are typically found in areas with unmanaged vegetation, such as parks, golf courses, sports fields, and other grassy spaces. These tiny larvae attach to humans, pets, and animals.
Unlike mosquitoes, chiggers don’t suck blood. Instead, they burrow into the skin and feed on dissolved tissue. The larvae inject saliva that causes the skin to break down, which is what they feed on. Although difficult to see, chiggers are often noticed by a reddish rash and intense itching.
Cloyd advises against scratching, as it can lead to bacterial infections. He recommends topical ointments to ease the itch and suggests consulting a dermatologist for additional remedies. Once the larvae have fed for a few days, they detach and transform into nymphs and adults, which reside in the soil and feed on insects, mites, and their eggs. Nymphs and adults do not feed on humans or animals.
To avoid bites, Cloyd recommends using DEET or other repellents in areas where chiggers are common. After returning indoors, showering immediately can help reduce itchiness. Chiggers are active from late April until the first frost, but the species in Kansas do not transmit diseases.
Cloyd also provides several tips for prevention:
- Avoid walking through tall grass and weeds.
- Do not sit, lie down, or walk barefoot in areas where chiggers may be.
- Tuck pant legs into socks.
- Regularly mow grass and remove overgrown vegetation.
- Wash clothes in hot water to kill any chiggers that may be attached.
- Consult a physician for advice on products to relieve discomfort.
