Earwigs are the dark-brown insects with distinctive pincers found in damp areas. Despite myths, they do not crawl into ears. Here is the Florida treatment guide.
How to identify earwigs
- 1/2 to 3/4 inch long.
- Dark brown body.
- Distinctive forceps-like pincers (cerci) at rear.
- Wings often present but rarely fly.
- Active at night; hide in moist dark areas during day.
Where they live
- Mulch beds and damp soil.
- Under rocks and logs.
- In basements and crawlspaces.
- Behind exterior siding.
- Inside damp leaf litter.
Why they enter homes
Earwigs enter homes seeking moisture (during dry weather) or shelter (during heavy rain). Florida humidity makes them year-round residents in many homes.
Treatment protocol
Step 1: Eliminate outdoor habitat
- Reduce mulch depth around foundation.
- Move mulch and leaf litter 12+ inches from foundation.
- Clear debris (logs, rocks, piles of leaves) within 6 feet of home.
Step 2: Apply Bifen IT to perimeter
Spray foundation perimeter, mulch beds, and entry points. Re-apply monthly during peak earwig season (spring through fall).
Step 3: Reduce indoor humidity
Run dehumidifier in basement, attic, and bathrooms. Target 40-50% humidity.
Step 4: Apply DE in entry points
Diatomaceous earth in baseboards, around door thresholds, and crawlspace entries.
Verdict
For earwigs in Florida, perimeter spray + outdoor habitat reduction + indoor humidity control prevents infestation. Most earwig issues resolve within 30 days of consistent treatment.
Reminder: Always read product labels and follow safety instructions.
