How to Get Rid of Chiggers and Fleas in Your Lawn

Insect bites are a common summer occurrence—itchy, burning, sometimes leaving raw welts, especially in sensitive individuals. If these pests plague your lawn, there are easy solutions to control the little bloodsuckers.

Know Your Enemy

Fleas: Biting insects primarily bothering animals, but in high infestations attack humans too. Live up to 2 years, thrive in warm weather. Bites cause welts, sometimes rashes. Reddish-brown, wingless, ~1/8 inch long, jump onto skin. Piercing/sucking mouthparts siphon blood.

Chiggers: Don't burrow into skin but inject digestive enzyme causing welts and itching. As chigger feeds, skin around bite swells and can cover the chigger—appears burrowed but isn't, making removal harder. Tiny larvae (0.25 mm) cause all the itching—difficult to spot.

Prevention & Personal Protection

• Clean lawn: Mow frequently, clean debris. Long grass clippings attract fleas/chiggers.
• Clothing: Long sleeves/pants outdoors. Tuck pants into socks/boots. Avoid lying in grass.
• After outdoors: Long sudsy shower to remove hitchhikers.
• Repellent: Spray clothing/exposed areas with DEET product. Avoid nose/mouth. Loses effectiveness in few hours—reapply as needed.
• Clothing care: Don't place clothing on grass—mites/fleas infest fabric, cause issues when re-worn.

Detecting Infestations

Fleas: Check pets first—black flecks (flea waste) in fur/skin. Check yourself after garden time.

Chiggers: Place black cardboard/paper at slight angle in grass. After few minutes, chiggers climb on. Test several lawn locations to find concentrations.

Chemical Control

Use pesticides labeled for chiggers/fleas. Determine concentration areas first to avoid overuse.

• Granular insecticides: Less effective than liquid sprays.
• Effective active ingredients: Permethrin (good chigger/flea control), Diazinon (good results), bifenthrin, cyfluthrin, esfenvalerate.
• Application: Hose-end sprayer at manufacturer's rate. Wear long sleeves/pants. Remove children/pets during/after spraying. Wait until liquid dries (~2 hours) before allowing play.
• Repeat: Treat again in 2 weeks to kill flea eggs.

Bite Care

• Wash bites thoroughly in warm, soapy water.
• Analgesics and anti-itch medications provide relief.
• Avoid scratching—welts can break open and infect.
• OTC chigger medications (numbing agents, sometimes sealants) may help.
• Extreme dermatitis reactions: see doctor.
• Babies/young children especially susceptible—immediate treatment needed.

Once adequate control agents applied, bites should stop or subside.
