Occasional Invaders in South Florida
Silverfish, millipedes, earwigs, springtails and more: the bugs that wander in after rain and what they say about moisture.

A heavy rain, a dry spell or a humid week pushes them toward doors, garages and bathrooms. Most don't bite and don't build big indoor populations, but finding them every morning gets old fast. Moisture control and a solid perimeter treatment keep most of them outside where they belong. Call or text anytime: 833-845-9284.

Rain, humidity and closed-up houses
Weather drives most of these calls. After a downpour, millipedes and pillbugs crawl out of flooded mulch beds and collect along door thresholds and in garages, and springtails jump in numbers during the rainy season. In a dry spell the pillbugs come in looking for moisture instead. Inside, these pests are a moisture gauge. Silverfish, springtails and drain flies are the usual tiny bugs in a bathroom, and all three point to damp grout, a slow leak or a drain that rarely gets used; our guide to tiny bugs in the bathroom helps you sort them out. Cool, breezy nights after a cold front can push a few more pests toward the house for a night or two; see cold front pests. Homes that sit closed up for the summer are where booklice do best, on damp books, boxes and window sills, and where silverfish settle into closets and storage. Our closing up for summer checklist covers what to do before you leave.
Which one is it?
| Pest | Size | Color | Where it's found | Key sign |
|---|---|---|---|---|
| Silverfish | About 1/2 inch | Silvery gray with a metallic sheen | Bathrooms, closets, attics, bookshelves, storage boxes | Damage to paper, books and photos |
| Millipede | Under an inch to several inches | Brown, black, gray or reddish | Mulch, leaf litter, under pots and pavers, garages | Curled-up bugs at the door after rain |
| House centipede | Body about 1 to 1 1/2 inches | Yellowish-gray with dark stripes | Bathrooms, closets, garages, under sinks | Very fast runner with long legs |
| Springtails | About 1/16 inch or smaller | Gray, white, black or bluish | Sinks, tubs, drains, potted plants, damp sills | Tiny specks that jump |
What we do and when to call
Silverfish and the other common household pests are covered by our $125 quarterly pest plan (about $42/month). Each visit treats the lower foundation wall and spot-treats door gaps, weep holes, window frames, pipe openings and eaves, where these pests get in. Many of them start outdoors and move in after heavy rain, so that perimeter is where we stop them. See our pest control services.
