How do you keep ants and roaches out of a home on Florida's Space Coast?
UF/IFAS recommends sanitation, sealing cracks, fixing leaks, and using baits. For Brevard County, Florida homes, avoid spraying near baits because sprays repel ants and spoil the bait.
Warm weather and plenty of moisture mean insects are part of life in Florida. If you are moving to the Space Coast from a colder state, you will probably meet ants and large roaches sooner than you expect, and that is normal.
The University of Florida's Institute of Food and Agricultural Sciences (UF/IFAS) publishes research-based fact sheets on both. This guide summarizes what those sheets say so you know what to expect in Brevard County and what steps tend to help.
What are palmetto bugs?
"Palmetto bug" is a common nickname rather than a single species. UF/IFAS says larger roaches measuring about 1 to 2 inches, including the American, Australian, brown, and smokybrown cockroaches, are often called palmetto bugs. These typically breed outdoors and only sometimes wander inside.
The Florida woods roach is described as the largest species. The Asian cockroach looks similar to the German cockroach but can fly and is attracted to lights on buildings, so you may notice them near lights around Melbourne, Viera, or Merritt Island homes. The German cockroach, about 5/8 inch long, is the species associated with kitchens and bathrooms. The full details are in the UF/IFAS fact sheet Cockroaches and Their Management.
What helps keep roaches out?
UF/IFAS describes an integrated approach that combines sanitation with targeted control. Relying on a single chemical alone risks resistance and poor results. The prevention priorities from the fact sheet include:
- Inspect groceries and remove cardboard boxes.
- Seal cracks, gaps, and screen openings.
- Repair plumbing leaks, since water is critical to cockroach survival.
- Remove food sources and clutter.
- Reduce mulch around foundations.
For control, the fact sheet says baits are the most highly recommended option because of their effectiveness and targeted application. Boric acid dust can be used in dry areas, and insect growth regulators take 4 to 6 weeks but last longer.
Which ants show up in Florida homes?
The UF/IFAS fact sheet on ants lists many pest species common in Florida homes, including pharaoh, white-footed, Argentine, ghost, pyramid, carpenter, rover, native fire, imported fire, crazy, thief, Caribbean, acrobat, and big-headed ants. Knowing which one you have matters, because control methods depend on where the nest is and what the ants are feeding on. You can read the whole sheet at UF/IFAS Ants.
How do you handle ants step by step?
| Step | What UF/IFAS says |
|---|---|
| Sanitation | Store food in tight containers and keep surfaces clean |
| Exclusion | Seal cracks and holes where ants enter |
| Debris | Remove nesting materials such as old lumber, firewood, and debris |
| Moisture | Reduce leaks and condensation |
| Locate the nest | Look for trails, mounds outdoors, or activity in walls and foundations |
| Bait | Granules, liquids, or gels let ants carry the toxicant back to the queen; use fresh bait in roughly 70 to 90 degree weather |
The one warning that stands out: do not spray insecticides around bait. Sprays repel ants and contaminate the bait, which makes it ineffective. It is a common mistake because spraying feels like action.
What should buyers look at on a Space Coast showing?
You will not inspect for every insect on a walk-through, but a few observations are worth noting at showings in Brevard County.
- Water stains under sinks or around toilets, since moisture feeds pests.
- Gaps around window screens, door sweeps, and plumbing penetrations.
- Mulch piled against the foundation.
- Stacked firewood or lumber against the house.
None of these are reasons to walk away on their own, and they are the kind of maintenance items that are simple to correct once you own the home. Your home inspector can note moisture and gap issues in the report, and you can plan a routine from there.
Frequently asked questions
Are palmetto bugs a sign of a dirty house?
Not necessarily. UF/IFAS says the larger roaches often called palmetto bugs typically breed outdoors and only occasionally enter homes.
Should I spray around ant bait?
No. UF/IFAS warns against spraying insecticides around bait, because sprays repel ants and contaminate the bait.
What is the best way to reduce roaches in a Florida home?
UF/IFAS recommends combining sanitation, sealing, and leak repair with baits, which it calls the most highly recommended option for effectiveness and targeted application.
