In South Florida, pest season never really ends. Heat and rain keep mosquitoes, ants, roaches, and termites active all year, which means the best defense is a set of habits, not an emergency response. September is a good moment to walk the perimeter of your home and close the small openings before the wetter weeks add more pressure.

Moisture is the magnet

Almost every pest problem in this climate starts with water. Fix dripping hose bibs and irrigation heads, clear gutters so downspouts drain away from the foundation, and look for puddles that linger after rain. Indoors, keep the humidity around 50% or lower and check under sinks and around the water heater. Dry corners are quiet corners.

Close the small openings

Roaches and ants follow gaps, not invitations. Check the sweep on every exterior door, the seal around garage doors, and the gaps where pipes, cables, and AC lines enter the house. Weatherstripping and a tube of exterior caulk cover most of the work. Screens matter too: one torn screen on a lanai is a welcome mat for mosquitoes.

Give the house some air

Vegetation touching the house gives pests a bridge and gives humidity a place to hide. Trim shrubs and palm fronds back from the roofline and foundation, keep mulch a few inches away from the walls, and store firewood and lumber off the ground and away from the structure. Elevated potted plants and a gap between soil and siding keep the base of the house easy to read at a glance.

The termite question

Termites are the one pest where the annual inspection earns its keep. Mud tubes on foundation walls, hollow-sounding wood, and discarded wings near windows are the signs to take seriously. Most South Florida homeowners pair an annual termite inspection with the simple habits above, and many pest control companies offer a plan that covers re-treatment if activity is found.

A calm, repeatable routine

None of this needs to be a project. An hour a month keeps the perimeter tidy, the screens whole, and the moisture in check. When you are house-hunting, the same checklist tells you a lot about how a home has been cared for, and Nanci is glad to point out the details buyers often miss on the outside of a house.
