How to Get Rid of Roaches in an Alabama House (and Why They Keep Coming Back)

The roach on the kitchen floor at midnight is one of the most common reasons anyone in Alabama calls a pest company, and it is also one of the most misunderstood. Most of the products sold to fix it make it worse. Most of the advice online assumes you know which roach you have, and most people do not. So this guide starts there, then walks the steps in the order that actually clears a house — and is honest about which step you cannot do yourself.

First: which roach is it?

Alabama homes deal with three, and they do not respond to the same fix.

• American cockroach — the "palmetto bug." Reddish-brown, big (an inch and a half or more), and it flies. It lives outdoors in sewers, storm drains, mulch, crawlspaces, and under decks, and it comes inside when it is very hot, very wet, or the drain trap dried out. You see it in the bathroom, the garage, or the laundry room, one at a time.
• Smokybrown cockroach — glossy dark brown, an inch, and it comes to porch lights. Lives in tree holes, gutters full of leaves, woodpiles, and attics. Same deal: an outdoor roach that visits.
• German cockroach — small, tan, two dark stripes behind the head, and it lives and breeds inside, in the kitchen and bathroom. If you see several small roaches, or tiny dark nymphs, this is your roach, and it changes everything about the plan. Read German cockroaches in Alabama before you buy anything.

The short version: big roach, occasionally, near a drain or a door — outdoor species, fix the perimeter. Small roaches, in numbers, in the kitchen — German, fix the interior. Our overview of all three species is in cockroach control in Alabama.

Step 1: Take away the water

Roaches can go weeks without food. They cannot go more than a few days without water, and in an Alabama summer the water in your house is the reason they are in it. Fix the drip under the sink. Run water into unused drains and floor drains weekly so the trap does not dry out — a dry trap is an open pipe straight from the sewer to your bathroom floor, and it is how palmetto bugs get into a clean house. Wipe the sink dry at night. Empty the pet water bowl overnight for a couple of weeks. Look at the dishwasher door gasket and the refrigerator drip pan.

If you do nothing else on this list, do this one. It makes every other step work faster.

Step 2: Cut the food to nearly nothing

You do not have to live in a sterile kitchen, but roaches are eating something and it is usually not the leftovers in the refrigerator. It is the grease film on the range hood and the side of the stove, the crumbs under the toaster and behind the cutting-board drawer, the pet food left in the bowl, the bag of dog food with the top rolled over, the trash can without a lid, the recycling with a sticky soda can in it, and the cardboard — roaches eat the glue. Boxes stacked in a pantry or garage are food and shelter at once.

Clean the grease, seal the pet food, lid the trash, break down the cardboard. Two evenings of work.

Step 3: Stop using the fogger

Bug bombs are the single most common reason a roach problem spreads from the kitchen to the rest of the house. The mist settles on open surfaces, which is where roaches are not. The repellent effect chases them from the crack behind the stove into the wall void and out into rooms they had not colonized. Then the residue on the counters repels them from the bait you put out next week. Aerosol sprays do the same thing on a smaller scale. Use neither.

Step 4: Bait, in the right places

Gel bait is the store product that actually works on roaches, and the reason is that it does not repel. The roach eats it, walks back to the harborage, and dies there; other roaches feed on the carcass and the droppings and the bait moves through the population. The rules:

• Small dots, many places. Pea-sized or smaller. Inside the cabinet hinge corners, under the sink at the plumbing penetration, behind the stove where the countertop meets the wall, under the refrigerator, inside the drawer runners, at the back of the pantry shelf.
• Where they live, not where you see them. A dot on the open counter gets ignored. A dot in the crack they hide in gets eaten.
• Do not spray anywhere near it. See Step 3.
• Refresh it. Gel dries out in a couple of weeks and stops being attractive.

For the outdoor species, bait is less central. What matters is the perimeter: a residual treatment along the foundation, around door and garage thresholds, and at the utility penetrations, so the roach that leaves the mulch bed at 2 a.m. dies before it finds the gap under the door.

Step 5: Close the entry points

The outdoor roaches are getting in somewhere specific. Walk the house at dusk with a flashlight. Door sweeps with daylight under them. The garage door bottom seal, especially the corners. The gap around the AC line set and the hose bib. Weep holes in the brick — leave them open for drainage, but a stainless mesh insert keeps roaches out. Torn crawlspace vent screens. Dryer vent flap stuck open. Firewood stacked against the siding. Leaf-filled gutters over the porch where smokybrowns nest. Trim any branch touching the roof. Our full checklist is in fall pest-proofing your Alabama home, and it applies in July just as well.

Step 6: Give it time, then judge

For an occasional palmetto bug: water, food, perimeter, and sealing usually end the visits within two or three weeks. For a German cockroach population: bait placed correctly should produce a sharp drop in a week and a clean kitchen in four to six, provided nothing is sprayed and the water is gone. If you are still seeing nymphs after a month of doing everything above, the population is larger than you can reach — likely inside a wall void, an appliance motor housing, or a neighbor's unit — and it needs a growth regulator and a technician who knows where to look.

When to call

• You are seeing small roaches in the kitchen in daylight. That is a German cockroach population that has outgrown its hiding places.
• You live in a duplex, townhome, or apartment and the problem persists no matter what you do. It is moving between units.
• Palmetto bugs are showing up weekly despite a clean house and a dry sink. There is a source under or beside the house — a broken sewer line, a wet crawlspace, a dense mulch bed against the foundation — and it needs an exterior treatment on a schedule.
• Anyone in the house has asthma. Cockroach allergen is a recognized trigger, and living with the population is not a good option.

Cockroaches are covered under EnviroCare's bi-monthly pest plan — $35 a month with a $75 initial service, exterior perimeter on a schedule, interior treatment as needed, and unlimited free re-service between visits if something shows up early. For a German cockroach problem, the first visit is an interior visit with bait, a growth regulator, and a follow-up built in. Whether you are in Pelham, Athens, or a lake house in Dadeville, that is how we clear it.
