Mobile pests, all year

Mobile, Alabama (population 182,595, Census 2023 estimate) sits in the warm, humid Gulf South, where pests do not take a winter break the way they do up north.

SeasonWhat to watch for in Mobile
SpringSubterranean termite swarms; Formosan termite swarms start on warm, humid evenings from late April into June.
SummerMosquitoes after rain, fire ant mounds, big outdoor roaches (palmetto bugs) wandering inside.
FallRats and mice look for shelter indoors as nights cool; roaches move toward warm kitchens.
WinterGerman roaches and bed bugs keep breeding indoors all year; a good time for termite and rodent exclusion work.

What treatment usually involves

  1. Inspection. A licensed tech finds where pests hide, feed and get in.
  2. Targeted treatment. Baits and crack-and-crevice products for roaches, traps and exclusion for rodents, soil treatment or bait stations for termites.
  3. Follow-up. Roaches and bed bugs usually need more than one visit to catch the next hatch.
  4. Prevention. Fix leaks, seal gaps, store food tight.

Landlords & property managers

Alabama's landlord-tenant act requires landlords to keep rental premises fit and habitable and to keep common areas clean and safe. Prompt treatment at unit turnover is the easiest time to get ahead of roaches and bed bugs, before the next tenant moves in.

Airbnb & short-term rental hosts

Bed bugs travel in luggage, so turnover between guests is when to check mattress seams and headboards. A roach on the counter can sink a review fast.

Restaurants & food businesses

The FDA Food Code requires food establishments to control pests and keep the premises free of insects and rodents. Commercial pest control usually means scheduled service and written records.

Why pests thrive in Mobile

Mobile is one of the wettest big cities in the country. NOAA's 1991–2020 normals for the Mobile Downtown Airport station show about 60.5 inches of precipitation a year, and the City of Mobile's visitor page puts the average at 66 inches. Either way, that is a lot of standing water, damp wood and wet mulch.

Warm, wet weather is exactly what many household pests need. UF/IFAS calls water the most important factor in cockroach survival. Subterranean termites need moisture from soil or wet wood. Mosquitoes breed in standing water. Rats and mice move toward food and shelter when storms flood their outdoor spots.

Mobile's winters are also mild. The City of Mobile lists an average winter low around 40°F, so many pests slow down in the cold months instead of dying off the way they do farther north. That is why pest pressure here is a year-round issue, not just a summer one.

Mobile pest calendar

Pests are active all year in Mobile, but some are worse at certain times. Here is a rough guide based on the sources below.

Late winter and spring (February–May)

Native eastern subterranean termites usually swarm in daylight in spring. Winged termites or piles of shed wings inside near windows and doors are worth a call. Ants start building new mounds as the soil warms up.

Late May and June

This is Formosan termite season in Alabama. The National Termite Survey lists late May to June as the Formosan swarm season in Alabama. They swarm at night and are attracted to lights, so you may see clouds of them around porch lights and streetlights. Alabama Extension says Formosan termites are most common in hot, humid coastal counties like Mobile and Baldwin.

Summer (June–September)

Heat, humidity and afternoon storms bring out palmetto bugs, mosquitoes and fire ants. Big roaches often show up after heavy rain floods sewers, mulch beds and tree holes. Get rid of standing water every week to cut down on mosquitoes.

Fall and winter (October–January)

Cooler nights push rats and mice toward attics, garages and wall voids. German cockroaches and bed bugs live indoors, so they do not care what season it is.

Roach types you'll see in Mobile

Not every roach means the same thing. Telling them apart helps you know whether you are dealing with a stray from outside or a problem breeding in your kitchen.

American cockroach (palmetto bug)

A large, reddish-brown roach. UF/IFAS shows the adult at about 1½ inches long. Along with other large species it is often called a palmetto bug. It prefers damp, warm places like sewers, garages, storerooms and crawl spaces, and comes indoors from those breeding sites.

Smokybrown cockroach

A uniformly dark, shiny mahogany-to-black roach, about 1 to 1¼ inches long according to UF/IFAS. Both sexes have full wings, fly well and are attracted to light. Texas A&M notes they need high humidity, so they live in tree holes, mulch, woodpiles and attics. They often get in through lit doors and windows at night. This is a very common "palmetto bug" in the Gulf South.

German cockroach

A small roach. UF/IFAS says adults of the smaller species are seldom more than ⅝ inch long. German cockroaches are usually found in kitchens and bathrooms and live indoors, close to food and water. If you see small, light-brown roaches in a kitchen, especially during the day, call a pro. This is the roach most likely to be breeding inside your home, apartment or restaurant.

What this means for you

UF/IFAS notes that outdoor roaches do not survive well indoors, and often just removing the ones that get in is enough. Small roaches multiplying in your kitchen are a different problem. They usually need baits, crack-and-crevice treatment and follow-up visits. See our roach guide for photos.

DIY or call a pro?

Where DIY can work

When to call a licensed pro

The EPA recommends integrated pest management (IPM): inspect, identify the pest, prevent it, and use pesticides carefully as one part of a larger plan. Always follow the label. The label is the law for pesticide use.

Sources: UF/IFAS: Cockroaches and Their Management · EPA: Do-it-yourself bed bug control · EPA: Introduction to IPM

What a pest visit usually looks like

1. Inspection

A tech looks at kitchens, bathrooms, under sinks, behind appliances, attics, crawl spaces and the outside of the building for signs of pests, moisture and ways in.

2. Identification

The right treatment depends on the species. German roaches, palmetto bugs, Formosan termites and native termites are each handled differently.

3. Treatment

Depending on the pest, this can mean roach baits and crack-and-crevice products, traps and sealing for rodents, liquid soil treatment or bait stations for termites, or a mix of methods for bed bugs.

4. Follow-up

Roaches and bed bugs often need repeat visits to catch eggs that hatch after the first treatment. Termite protection is usually set up as an ongoing plan with regular inspections.

5. Cost

We do not list prices we cannot source. Costs vary by pest, square footage and plan. UF/IFAS suggests getting estimates from several reputable firms. Call and ask for a written quote and the company's Alabama license details.

Renters & landlords in Mobile

For renters

Write down what you see: photos, dates, which rooms. Report pests to your landlord or property manager in writing so there is a record. Do not spray bug bombs or outdoor-only products inside an apartment. They can spread pests to neighboring units and are not made for indoor use. Read your lease to see what it says about pest control.

For landlords and property managers

German roaches and bed bugs can spread between units that share walls, plumbing and attics, so one complaint is worth a fast inspection. Unit turnover is the easiest time to inspect and treat before a new tenant moves in. Keep records of inspections and treatments. Our landlord page lists the Alabama law source we use. This guide is not legal advice.

Airbnb & short-term rental hosts

Guests bring luggage, and the EPA notes that bed bugs travel in luggage, clothing and furniture. A short check during each turnover can catch problems early.

Turnover checklist

If a guest reports bugs

Ask for a photo, keep the unit empty if you can, and call a licensed pro to identify the pest before the next booking. Do not use foggers. The EPA cautions against relying on them for bed bugs.

Restaurants & food businesses

The FDA Food Code, which many health departments base their rules on, requires food establishments to control pests and keep the premises free of insects and rodents (§6-501.111). German cockroaches are especially common in commercial kitchens because they live close to food, water and warmth.

Daily habits that help

Work with a licensed pro

Ask for scheduled service, written service reports and pest sighting logs you can show an inspector. Call as soon as staff see roaches or rodent droppings.

How to choose a Mobile pest company

When you need pests gone fast, it is tempting to hire whoever answers first. A few questions on the phone can save you a repeat problem later.

Write down the company name, the tech's name, the date and what was done. That makes follow-ups and any later disputes much easier.

Termites: Mobile's biggest risk to buildings

Alabama Extension says Formosan subterranean termites are "the most dreaded destroyer of homes" and are most common in hot, humid coastal counties like Mobile and Baldwin. They also warn that signs of termite damage may not show until a lot of damage is already done, so regular inspections matter.

Signs to look for

Other Mobile pests

Fire ants

Mobile County falls under the federal imported fire ant quarantine. Mounds show up in lawns, along driveways and around utility boxes. See our fire ant page.

Rats and mice

The CDC's advice is seal up, trap up and clean up: close openings, trap rodents, and clean up droppings safely. See our rodent guide.

Bed bugs

The EPA says bed bugs are not known to spread disease, but they are hard to get rid of. See our bed bug guide.

Mosquitoes

With 60+ inches of rain a year, standing water is everywhere. CDC guidance is to remove standing water every week.

Mobile pest control FAQs

Are palmetto bugs the same as cockroaches?

Yes. UF/IFAS says the larger cockroaches, including the American and smokybrown, are often called palmetto bugs. They usually live outdoors and come inside when they wander in or are carried in.

Why do I see big roaches after it rains?

Water is the most important factor in cockroach survival, according to UF/IFAS. Heavy rain floods outdoor hiding spots and drives them toward shelter. They also move indoors during dry spells when they are looking for moisture.

Is one big roach a sign of an infestation?

Not always. UF/IFAS notes that outdoor cockroaches do not survive well indoors and that people often overreact to them. Small roaches in the kitchen or bathroom, seen in daylight or in numbers, are more likely to be German cockroaches breeding inside. That is the time to call a pro.

When do termites swarm in Mobile?

Formosan subterranean termites in Alabama swarm in late May to June, at night, and they are drawn to lights. Native eastern subterranean termites usually swarm in daylight earlier in the spring.

Can I get rid of bed bugs myself?

The EPA says do-it-yourself control is possible in some cases, but bed bugs are hard to eliminate and the EPA recommends a pest management professional for many infestations. Do not use outdoor-only pesticides indoors.

How much does pest control cost in Mobile?

Prices depend on the pest, the size of the property and the plan, so we do not publish numbers we cannot back up. UF/IFAS advises getting estimates from several reputable firms. Call and ask for a written quote.

Is pest control licensed in Alabama?

Yes. Commercial pest control in Alabama is regulated by the Alabama Department of Agriculture and Industries. You can ask any company for its license number before work starts.

Who pays for pest control in a rental?

It depends on Alabama law, the lease, and what caused the problem. See our landlord section and source, and read your lease. This guide is not legal advice.

Oriental cockroach (waterbug)

Oriental cockroach (waterbug)

SizeMales 18–29 mm, females 20–27 mm
Egg case16–18 eggs per case
Hatch timeAbout 42 days at 29°C; 81 days at 21°C
ColdEggs lose viability below 0°C

Where found: Damp areas, hence the nickname waterbug.

A large, glossy dark-brown to black cockroach. Females look nearly wingless and neither sex can fly. It favors damp spots, and its blackish-brown egg cases are a common sign it is present.

What it means for your home: Moisture is the draw: fix leaks and damp crawl spaces, and seal entry points.

Yellow fever mosquito (Aedes aegypti)

Yellow fever mosquito (Aedes aegypti)

Adult lifespan2–4 weeks
Egg survivalDry eggs viable over a year
BitingMost at dusk and dawn, but can bite any time
BreedingLays eggs in water containers

Where found: Around homes: buckets, planters and any container holding water.

An invasive mosquito that can spread dengue, yellow fever and chikungunya. Only females bite. Its eggs survive dry for over a year, so they re-emerge after cold or dry spells.

What it means for your home: Dump and scrub water containers weekly; treat standing water you cannot drain.

Smokybrown cockroach

Smokybrown cockroach

Size32–35 mm long
Water lossLoses moisture about twice as fast as the American roach
WarmthActive when temperatures are above about 20°C (68°F)
Egg case11–14 mm; a female can produce 10 or more

Where found: Tree holes, mulch, woodpiles, gutters and attics; flies toward lit doors and windows at night.

A uniformly dark, shiny mahogany-to-black roach with full wings in both sexes. It dries out easily, so it lives where humidity is high, which is why it is one of the most common "palmetto bugs" in humid Gulf Coast neighborhoods.

What it means for your home: Trim branches off the roof, clean gutters and keep mulch back from the slab; frequent indoor sightings deserve a perimeter treatment by a pro.
