Cleanliness is not the variable that decides whether a Florida home gets roaches. Moisture, entry points and plumbing decide it. A spotless kitchen with a slow leak under the sink is more attractive to a roach than a cluttered one that stays dry — and the roach most Florida homeowners see did not come for the crumbs. It came in from the yard looking for water. First, though, you need to know which of two very different situations you are in.
Two problems wear the same word
The big reddish-brown one that sprints across the tile at night is almost always an American cockroach — what Floridians call a palmetto bug. It lives outdoors, in mulch, palm boots, sewer lines and irrigation boxes, and it visits. The small light-brown one with two dark stripes behind the head is a German cockroach, and that one does not visit: it breeds indoors in kitchen and bathroom voids, and it arrives by being carried in.
What actually attracts them, in order

- Water first. A sweating pipe, a sink trap that weeps, an A/C condensate line, a pet bowl left down overnight. A roach can go a long stretch without a meal and nowhere near as long without water.
- Warm, tight, dark space second. The motor housing under the fridge, the void behind the dishwasher, the hinge gaps of cabinet doors. Harbourage is not about dirt, it is geometry.
- Food last, and not the food you are picturing — the grease film behind the stove, the drip tray under the fridge, the dog food in its paper bag in the garage, and cardboard, which is warm, dark, edible and often the thing that carried them in.
Wiping visible surfaces is what most people mean by a clean kitchen. Roaches live and feed in the gaps — behind, beneath and inside the appliances — where a cloth has never been. That is how a kitchen can be immaculate and still feed a population.
How they got in when nobody left a door open
- Plumbing penetrations. The hole cut for a drain pipe under a sink is nearly always wider than the pipe, and it opens straight into the wall void.
- Floor drains, clean-outs and sewer lines, which is why a guest bathroom nobody uses can still produce one. Weep holes, garage door corners and a torn lanai screen do the rest.
- Carried in — grocery bags, delivery boxes, a secondhand microwave — or through the shared walls of a duplex, where your unit is only as treated as the ones either side.
So does cleaning matter at all?
It matters, just not for the reason people assume. Sanitation does not decide whether roaches arrive; it decides how fast a population grows once they do, and how well treatment works — gel bait has to be the most appealing thing in the room, and grease in every seam competes with it. What cleaning cannot do is close a gap or dry a leak.
Leave the kitchen dark for a few hours, then walk in and turn the light on. Several small roaches, or any roach in daylight, points to an established indoor population. One big one at midnight points outside. That difference decides the treatment.
If it turns out to be German roaches, the long version is in our guide to getting rid of German roaches in Florida. If it is palmetto bugs, the work is outside at the perimeter. Our cockroach and German roach control covers both, with local detail on the cockroach control page for Melbourne. The inspection is free, and if your house is clean you will not be told otherwise.
