Coming back to your Florida home after summer, the first thing most people want to do is drop the bags and crank the AC. Give it twenty minutes first. Before you unpack, walk the house and look for four things: dry drains, droppings, roach activity in the kitchen and bathrooms, and water sitting outside. Your house just spent the busiest pest months of the year shut up, hot and undisturbed. Catching the signs on day one keeps a small problem small.

Why a closed-up house is easy pickings

Pests like a house nobody's using. There's no foot traffic, no lights going on and off, nobody opening cabinets. A roach that wanders in through the garage in July can spend August and September exploring without ever being seen.

The plumbing matters more than most people think. Every sink, tub, shower and floor drain has a curved trap that holds a little water. That water is the seal between your house and the sewer line. Leave a drain unused for a few months, especially with the AC set high, and the water evaporates. Now it's an open pipe, and big roaches and drain flies can walk right up. Our post on roaches coming up the drain covers what to do.

Meanwhile, outside, the summer rain kept coming. Mulch beds stayed wet, gutters filled and anything that holds water held it.

The first hour, room by room

Grab your phone flashlight. You're not cleaning yet, just looking.

Kitchen. Open the cabinet under the sink and check the back corners and the spots where the pipes come through the wall. Pull out the drawer under the oven if you have one. Look along the edge of the fridge and in the pantry, especially at anything in paper or cardboard. Roach droppings look like ground pepper or tiny dark smears. An egg case is a small brown capsule, roughly the size of a grain of rice.

Bathrooms, especially the guest bath. This is the one nobody touched since spring. A big roach on its back in the tub is a classic welcome-home sight. Tiny gray flies hovering over the sink are usually drain flies, and they point straight at a dry or dirty drain.

Garage. Rodents run along walls, so check where the floor meets the wall, behind stored boxes and around any bag of birdseed or pet food. Chewed corners on bags and a musty smell are the giveaways.

AC closet and attic hatch. The air handler closet stays damp from condensation, which makes it a water stop for pests. Then pop the attic hatch and shine the light around. Flattened or torn insulation, droppings and chewed duct wrap or wiring mean something's been living up there.

Lanai and eaves. Look for webs in the corners, wasp nests under the eaves or inside shutter tracks, and water sitting in saucers, planters and pool covers. If you find a wasp nest, leave it alone and call us; nest removal is part of what we do. If it's honey bees, call a local beekeeper instead; we don't remove hives.

Run every tap and flush every drain

This is the easiest fix on the list, and it works right away. Turn on every faucet, run every shower and tub, flush every toilet and pour a bucket of water into the laundry or garage floor drain. Half a minute per drain is plenty to refill the trap and close that open door from the pipes.

If you see a few roaches come up while you do it, that tells you where they've been getting in. Make a note of it for your technician.

Next time you leave, close the tub and sink stoppers. It slows the evaporation and makes a decent backup seal.

What the droppings are telling you

Roach droppings are small, like pepper, and you'll find them in cabinet corners, hinges and drawer tracks. Rodent droppings are bigger, pellet-shaped and usually show up in a line along a wall, in the garage, the attic or behind the fridge.

Don't sweep or vacuum rodent droppings; that stirs up dust you don't want to breathe. Open doors and windows and let the space air out for 30 minutes first. Put on rubber, latex or vinyl gloves, spray the droppings with a household disinfectant or a bleach solution (1 part bleach to 10 parts water) until they're soaked, and let it sit 5 minutes. Wipe them up with paper towels, bag them and put the bag in a covered outdoor trash can. Then disinfect the spot, and wash your hands after you take off the gloves. If there are a lot of droppings, like throughout attic insulation, call us before you start.

If it's rodents, call before you start setting out your own bait. We inspect for entry points, set traps and tamper-resistant bait stations, and seal the gaps rodents are using with exclusion work, to help keep them from getting back in. Inside the home we use snap traps only, never loose bait. Bait stations stay outside. More on our rodent control page.

Water sitting outside

A summer's worth of rain leaves water in places you forget about, and every one of them can raise mosquitoes for weeks after you're back. Walk the yard and tip out what you can. Our guide to mosquito breeding sites covers the spots people miss. If you'd rather hand it off, our mosquito service includes larvicide on breeding spots around the home.

When coming back to your Florida home after summer means a call

One big roach in the tub after months away is normal for South Florida. These are worth a call:

  • Roaches in more than one room, or more than a couple in the first day
  • Small, light-brown roaches in the kitchen, which usually means they're breeding inside
  • Rodent droppings anywhere, or scratching in the attic or walls at night
  • Drain flies that keep showing up after you've run the water

Big outdoor roaches are often palmetto bugs that came in from the yard or the drains. Our pest control service starts with a FREE inspection, and new customers get $50 off the first service.

Keeping the house covered while you're up north

Here's the part a lot of seasonal owners don't know: we service seasonal homes while the owners are away. Access is usually a lockbox, your property manager, or sometimes your cleaning service. Regular visits all summer mean someone is looking at the house, refreshing treatments and catching problems before you fly back.

Our general pest plan is $125 per quarter, about $42 a month. Monthly or custom schedules are quoted after the inspection. For plan customers: "If pests come back between visits, so do we, at no extra cost." There are no long-term contracts and no cancellation fees, just a simple service agreement. We're family-run, licensed, in business for 30+ years, and hablamos español. See plans and pricing.

If you rent the place out while you're gone, our guide for Airbnb hosts covers turnover between guests. And when spring comes and you're closing up again, we'll have a checklist for leaving too. Until then, browse more of our guides.

Back-for-the-season FAQs

How long can roaches live in a vacant house?
Longer than most people expect. Roaches can go weeks without food as long as they find water, and a closed-up house usually has some: a slow drip under a sink, condensation in the AC closet, a toilet bowl. That's why the kitchen, the bathrooms and the air handler closet are the first places to check.
What are the worst months for cockroaches?
In South Florida, the big outdoor roaches come inside most during the warm, rainy months, roughly late spring through fall, when storms flood them out of drains and mulch. That's exactly the stretch most seasonal homes sit empty. Small indoor roaches breed in any month.
How do bugs come back after winter?
Down here they never really leave. South Florida doesn't get a winter cold enough to shut pests down, so when you return in the fall, your house has just been through peak season. The pests didn't come back; they were active the whole time you were gone.
Do roaches ever fully go away?
Outdoor roaches are part of life in South Florida, so the goal is keeping them outside and stopping them at the doors, drains and gaps. An indoor infestation is different. With the right treatment and follow-up visits, it can be cleared out, and regular service helps keep it from starting again.
