A closed-up Southwest Florida home invites ants, cockroaches, rodents, termites, wasps, lizards and larger wildlife, and the damage is often quiet until it is expensive. A regular visual inspection can catch early signs such as droppings, mud tubes, wood dust and nests. Home watch is not pest control, so any finding goes to a licensed professional.

Updated October 3, 2026

An empty house has no one to notice a trail of ants, a scratching sound or a new nest. This guide from True North Home Watch, for owners in Naples, Marco Island and Bonita Springs, covers what to watch for, how to prepare before you leave and what to do if something turns up. It is general information, not pest control or legal advice.

Key takeaways

Vacant homes go unnoticed longer, so small pest signs can grow before anyone sees them.
Signs a visual check can spot: droppings, gnaw marks, mud tubes, six-sided termite pellets, nests and entry gaps.
UF/IFAS Extension says mice fit through a 1/4-inch gap and rats through a 1/2-inch gap, so sealing matters.
Fix leaks and moisture before you leave. UF/IFAS lists moisture as a factor for ants and termites.
In Florida it is illegal to exclude bats from April 16 through August 14 (FWC).
Home watch reports and photographs. Licensed pest professionals diagnose and treat, coordinated only with your approval.

Which pests and wildlife turn up in a vacant Southwest Florida home?

Warm weather and plenty of moisture keep pests active year-round in our area. These are the ones we would expect owners to hear about most, based on UF/IFAS Extension and Florida Fish and Wildlife Conservation Commission (FWC) guidance.

Pest or wildlife	What to know	Typical sign
Ants	UF/IFAS says small ants can enter through extremely small openings and nest in walls, behind baseboards and near foundations.	Trails, small piles of debris, ants around a sink or window
Cockroaches	The American cockroach lives in and close to buildings. The Florida woods cockroach, often called the palmetto bug, generally stays outdoors.	Live or dead roaches, especially near kitchens and baths
Rats and mice	Roof rats thrive in attics, roof spaces, palm trees and shrubs, per UF/IFAS.	Droppings, gnaw marks, greasy rub marks, sounds in the ceiling
Subterranean termites	Build mud tubes to travel above ground and swarm in spring.	Mud tubes, discarded wings, damaged wood
Drywood termites	Live inside wood and push out six-sided fecal pellets.	Small piles of pellets below tiny kickout holes
Wasps	Paper wasps build honeycomb-like nests, commonly under eaves or window ledges.	Nests under eaves, window ledges and porch roofs
Geckos and lizards	House geckos gather near lights hunting insects. UF/IFAS says some people choose to leave them, as they eat moths and roaches.	Geckos near porch lights and windows
Wildlife	Raccoons, opossums, snakes and bats are covered in FWC guidance for living with wildlife.	Droppings, staining near openings, noises, dusk activity

Not every sighting is a problem. FWC says the simple presence of wildlife, even in urban areas, should not be considered a nuisance. It becomes one when animals cause property damage or annoyance in, under or on a building.

What signs can a visual home inspection spot?

A trained eye walking the same route each time notices what changes. Home watch is a visual inspection, so we look for evidence and report it, rather than diagnose it. On a visit, that can include:

Droppings. UF/IFAS says most people first recognize a rodent problem by finding droppings or urine stains. Fresh droppings are black and shiny, and old ones are gray and crumbly.
Gnaw marks and chewed materials. Fresh marks are light with sharp edges. Rodents chew constantly, so chewed wiring, boxes or insulation deserves a prompt report.
Mud tubes. UF/IFAS describes these as made of soil, termite feces and partially digested wood, which they use to travel above ground.
Frass and kickout holes. Drywood termites push six-sided fecal pellets out of holes about the size of a pen tip.
Nests. Wasp nests under eaves and on the lanai, or debris and nesting material in garages and soffits.
Entry points and damage. Torn screens, gaps around pipes, gnawed door edges or displaced vent covers.

Some of these live where nobody looks: inside walls, in attics and under slabs. A visual check can miss hidden activity, which is why a licensed termite inspection is a separate service. UF/IFAS suggests an annual renewal inspection by a trained and licensed termite inspector.

Each visit covers your home inside and out, with photos. Our guide to what a home watch visit includes walks through the routine.

What should I do before I leave for the season?

Prevention is far easier than cleanup. Most of it is basic housekeeping, and it lines up with what UF/IFAS and FWC recommend.

Clear out food. UF/IFAS says to store food in tight containers, and that the best approach to ant control in the home is cleanliness. Remove perishables, pet food and anything open in the pantry.
Take out all trash. Empty every can, including bathrooms and the garage, before you go. Keep outdoor garbage in a secure container. FWC says wildlife will return to unsecured food sources even after one visit.
Seal gaps. UF/IFAS says mice can pass through a 1/4-inch opening and rats through a 1/2-inch crack. Check around pipes, vents, doors and the garage, and use materials such as hardware cloth or sheet metal for larger openings.
Give the house room. For termites, UF/IFAS advises an inspection space of at least 6 inches between siding and the soil or mulch line, plants at least 2 feet from exterior walls and branches that do not touch the roof.
Move wood and debris. Piles of lumber, firewood and debris can serve as ant nesting sites, and UF/IFAS says to eliminate wood-to-ground contact. Firewood can also carry Florida woods cockroaches indoors.
Remove wildlife attractants. FWC says to remove or maintain feeders, manage fruit-bearing plants and seal crawlspaces and entry points.

Our closing-up checklist puts these steps in the context of a full season-end shutdown.

Why do moisture and humidity matter for pests?

Water is one of the most common things pests have in common. UF/IFAS advises reducing moisture sources for ants, including condensation and leaks. For termites, it advises fixing leaks and making sure water runs away from the structure, not toward it.

A closed-up home can hold moisture that no one sees: a slow drip under a sink, a clogged A/C drain line, a wet spot on the lanai. Keeping the air conditioning running and checking for leaks reduces conditions that invite trouble. Our guide to managing humidity in a Florida home covers this side of the problem.

Is home watch pest control?

No, and it shouldn't be confused with it. Home watch is a scheduled, visual inspection of your home while you are away. We look for signs of trouble and report them to you with photos, and we do not apply or handle treatments.

A neighbor might spot an obvious problem, but our home watch services follow a set route on a regular schedule and leave a documented record. We explain the difference in why a neighbor isn't home watch.

When treatment is needed, True North coordinates licensed pest control professionals, but only with your approval. Our concierge services can also let a vendor into the home, meet them there and report back on what was done, so you do not have to arrange a visit from out of state.

What happens if something is found?

We document it. You get a report with photos showing where the sign was and what it looked like.
We tell you promptly. You decide how to proceed.
With your approval, we coordinate a licensed professional. That may be a licensed pest control company or, for some wildlife, an FWC-registered nuisance wildlife control operator. FWC does not license trappers, though trappers can voluntarily register with it.
We meet the vendor and follow up. After the work, we check the home again and report back.

Two cautions for owners. First, FWC says trapping and relocating or killing native wildlife should be a last resort, and that removing certain species, including bats, is restricted. FWC says it is illegal to evict or exclude bats during maternity season from April 16 to August 14. Second, please don't attempt treatments in a house you can't monitor. Leave treatment choices to a licensed professional who can inspect in person.

Ask any provider about their licensing before they start work. Coverage for pest damage varies by policy, and our article on vacant home insurance in Florida covers what to ask your agent.

What do owners ask about pests in a vacant home?

Does a home watch visit include pest control?

No. Home watch is a visual inspection, not pest control. A True North visit looks for signs such as droppings, mud tubes, wood dust, chewed material and nests, and reports what it sees with photos. If something turns up, we coordinate a licensed pest control professional to evaluate and treat it, only with your approval.

What are the first signs of termites in a Florida home?

UF/IFAS Extension says subterranean termites build mud tubes made of soil, termite feces and partially digested wood, and swarm in spring. Drywood termites push out six-sided fecal pellets through pen-tip-sized kickout holes. Any of these signs is a reason to call a licensed termite inspector rather than guess.

Are palmetto bugs the same as American cockroaches?

Not always. UF/IFAS Extension notes the Florida woods cockroach is the native insect commonly called the palmetto bug, and it generally stays outdoors in leaf litter and around dead trees. The American cockroach is an introduced species usually found in and close to buildings. Roaches inside a vacant home are worth reporting either way.

Can I have bats removed from my house in summer?

Probably not right away. The Florida Fish and Wildlife Conservation Commission says it is illegal to evict or exclude bats during maternity season, April 16 through August 14, because pups can't yet fly. Exclusion is allowed from August 15 through April 15. Contact FWC or a qualified professional before doing anything.

Should I set traps or bait stations in my empty house?

We suggest leaving that to licensed pest professionals. UF/IFAS notes trapping works for small rodent problems, but larger ones need a more complete approach. Loose traps and baits in a closed house can also be forgotten, and unattended catches create their own problems. Tell your home watch company about any activity instead.

What should I do before leaving to keep pests out?

Empty the kitchen of perishable food, store what remains in tight containers, take out all trash, seal gaps around pipes and doors, and keep plants 2 feet from the walls and branches off the roof. Fix leaks before you go, since UF/IFAS lists moisture as a factor for both ants and termites.
