Chiggers in Alabama: What They Are and How to Keep Them Out of the Yard
The itching starts hours after you were in the tall grass, in a ring around the sock line and the waistband, and it is worse than any mosquito bite. Chiggers are not insects, they do not burrow, and most of what people believe about them is wrong. Here is what they are and what lowers the risk.
Nobody sees a chigger. They are the larval stage of a mite, smaller than the period at the end of this sentence, and they wait on grass stems and leaf litter for something warm to walk by. Hours later you have a cluster of intensely itchy welts at the sock line, behind the knees, or at the waistband, and the myths start: they burrow into the skin, nail polish suffocates them, they came from the Spanish moss. None of that is true. Here is what is.
What a chigger actually does
A chigger larva crawls until it hits a tight spot — a sock band, a waistband, the crease behind the knee — attaches to the skin, injects saliva that digests skin cells, and feeds on the liquid for a few hours to a couple of days. It does not burrow and it does not lay eggs in you. The welt and the itch are your reaction to the saliva, which is why the itching starts hours later and lasts a week or more. By the time you itch, the chigger is usually already gone. Nail polish does nothing except seal a bite that no longer has anything in it.
Where they are in Alabama
Chiggers need humidity and shade, and they concentrate in exactly the places ticks do: tall grass, the unmowed edge of the lawn, leaf litter under shrubs, the tree line, damp low spots, and the overgrown strip along a fence or a creek. They are active from late spring through early fall and peak in the summer heat. Lake lots with a shoreline of tall grass, wooded lots in Hampton Cove or Chelsea, and any yard that backs up to pasture or woods carry the most pressure.
Lowering the risk in the yard
- Mow, and mow the edges. Short, sunlit grass is hostile to chiggers.
- Rake and remove leaf litter under shrubs and along fences.
- Put a band of wood chips or gravel between the lawn and any woods or tall grass.
- Keep play areas and seating in the open, sunny part of the yard.
- Treat the edge zones. A residual yard treatment on the tree line, the shrub beds, and the unmowed margins is what reduces chigger and tick populations where they actually wait.
Lowering the risk on you
Repellent with DEET or picaridin on ankles and waist, used as the label directs, before time in tall grass. Long pants tucked into socks. And the two-hour rule: shower with soap soon after coming in, scrubbing the sock line and waistband, which removes any that have not attached. Wash the clothes in hot water. For the bites, an anti-itch cream and not scratching are the whole treatment; if a bite looks infected, see a doctor.
Chiggers are covered with ticks
EnviroCare's Mosquito + Tick program treats the edge zones where chiggers and ticks wait, on a monthly schedule from March through October, and chiggers are covered under it — fleas are not; that is an interior add-on. It reduces the population in the treated areas substantially; it does not make a wooded lot chigger-free, and we say so.
