Almost every Florida homeowner has had the moment: you flip on the kitchen light at eleven at night and something the size of your thumb sprints across the tile. Palmetto bug — the local name for the American cockroach and its close relatives. Here is the thing that changes how you deal with them: they are not living in your kitchen. They live outside, in mulch, palm boots, sewer lines and irrigation boxes, and they come in looking for water. Which means every one you squash indoors is a symptom, not the problem.
Why they come in, in the order it usually matters
- Water. Ours is a wet coast, but a palmetto bug will still cross a threshold for a leaking hose bib, a condensate line or a damp bathroom.
- Heavy rain. When the ground floods, the ones living in the soil and drains move up and out. A surge indoors right after a storm is normal, not an infestation.
- Gaps. Under the garage door, around the dryer vent, the gap where a pipe enters the wall, a torn window screen.
- Harbourage against the house. Mulch piled against the foundation, palm fronds and boots, firewood, a thick hedge that never dries out.

One: dry the perimeter. Two: seal the entries. Three: treat the harbourage, not the living room. In that order — because if you skip straight to spraying indoors you are treating the one you saw, while the fifty you did not see are still in the mulch.
Walk the outside of your house at dusk with a flashlight and look at the bottom eighteen inches: mulch touching stucco, a hose bib dripping, a gap under the garage door you can see light through. That walk finds more than a can of spray fixes.
Palmetto bug or German roach? It changes everything
If the roach is big, reddish-brown and you see it alone at night, that is a palmetto bug and the work is outside. If it is small, light brown with two dark stripes behind the head, and you are seeing several — especially in daylight — that is a German roach, it is breeding inside your kitchen, and the treatment is completely different. People lose months treating the wrong one.
What we do that you cannot buy in a box
A perimeter treatment puts a residual barrier where they actually travel — the base of the exterior wall, the weep holes, the utility penetrations, the irrigation and sewer boxes — and pairs it with bait in the harbourage. Retail sprays break down fast in our sun and rain, which is why the DIY version needs redoing constantly and the professional version is scheduled around how long the product actually lasts on the Treasure Coast.
Pull the mulch back so there is a bare few inches between it and your stucco. It costs nothing, it dries out the exact strip they live in, and you will notice the difference in a few weeks.
If you have done the perimeter walk and you are still getting them weekly, that usually means a harbourage you cannot see — a sewer clean-out, a void under a slab, a neighbouring lot. Rhino covers the Treasure and Space Coast, and the inspection is free, so you can find out before you buy another can of anything.
