Here's some info about prevention and treatment of chigger bites.
You sat in the grass. Pulled some weeds. Picked up
sticks. Went inside. Showered.
12 hours later your ankles, waistband, and armpits
are on fire. Tiny red bumps. Intense, maddening itch.
Worse than mosquito bites. WAY worse.
Chiggers.
Chigger larvae are nearly invisible — smaller than
a period at the end of a sentence. They hang out on
the tips of tall grass and brush, waiting for
something warm to walk by.
When you brush past, they climb on. They migrate to
tight spots — sock lines, waistbands, underwear
elastic, armpits, behind knees — anywhere clothing
presses against skin.
Then they inject enzymes that dissolve skin cells.
They create a feeding tube called a stylostome and
feed for 3-4 days before dropping off.
The itch isn't from a bite. It's your body's allergic
reaction to the stylostome. And it intensifies for
days. The itch peaks 24-48 hours after exposure and
can last 2 weeks.
The myth: chiggers burrow into skin. They don't.
They attach on the surface. They're gone within hours
of your first shower. But the damage is done.
Where they live:
Tall grass. Brush edges. Garden borders. Unmowed
areas. Anywhere humid and shaded. Peak season:
June through September.
Prevention:
Wear long pants tucked into socks (or boots) when
in tall grass.
Apply permethrin to clothing (kills chiggers on
contact before they reach skin).
Apply DEET or picaridin to exposed skin.
Shower within 1-2 hours of outdoor activity —
they can be washed off before they start feeding.
Scrub hard with a washcloth — they're tiny and
grip weakly.
Hot wash all clothes after outdoor work.
Treatment:
The chigger is gone. You're treating the reaction.
Hydrocortisone cream.
Calamine lotion.
Antihistamines (Benadryl, cetirizine) for itch.
DO NOT scratch — secondary infection is the real
danger.
Clear nail polish on the bites does NOT help — the
chigger is already gone.
20 minutes in the grass. 2 weeks of misery.
Shower fast. Scrub hard. Cover up.
