Know your enemy: the pests that actually run the Gulf Coast.
Mobile County sits in Termite Infestation Probability Zone #1 — the heaviest pressure rating the International Residential Code assigns. Add port-city hitchhikers, subtropical humidity, and mild winters, and the local pest roster looks nothing like the rest of Alabama’s. Identify what you’re seeing below, then enter your ZIP to get connected with an independent, ADAI-licensed operator.

Why Mobile’s pest roster is different
Two centuries of shipping through the Port of Mobile brought species the rest of the state never sees at scale: the Formosan subterranean termite arrived through Gulf ports, the red imported fire ant made its North American landfall here in the late 1930s, and the black imported fire ant came through even earlier. The Mobile County Health Department runs active surveillance for mosquito-borne disease, and the IRC gives the county its heaviest termite-probability rating.
All of that changes what “pest control” means locally. Species identification is the first job on every call — an American cockroach coming up a floor drain, a smokybrown dropping out of oak canopy onto the roofline, and a German cockroach breeding behind the refrigerator are three different treatment plans. The pages below give you the ID points, the local behavior, and what a licensed operator typically does about each one.
Mobile Alabama Exterminators is a dispatch and referral service — the independent, ADAI-licensed operator we match you with performs every inspection and treatment. Any operator’s license can be verified with the Alabama Department of Agriculture and Industries at (334) 240-7240 before you hire.
The Gulf Coast pest library
Grouped by category — every link goes to a full identification and treatment guide.
Termites
- Formosan subterranean (Coptotermes formosanus) — the flagship Mobile threat; night swarms, May–June
- Eastern subterranean (Reticulitermes flavipes) — native; daylight swarms Feb–May
- Southeastern drywood — no soil contact; spring night swarmer
Ants
- Red imported fire ant (Solenopsis invicta) — Port of Mobile entry, late 1930s
- Black imported fire ant (S. richteri) — arrived ~1918
- Carpenter ant — wood-damaging; traces to moisture
- Argentine ant — supercolonies along the Gulf corridor
Cockroaches
- American cockroach — the “palmetto bug”; sewers and drains
- Smokybrown — oak-canopy roach of the historic districts
- German cockroach — kitchen breeder; the true infestation species
- Florida woods cockroach — the “stinking” outdoor roach
Rodents
- Roof rat (Rattus rattus) — attic and tree-line runner; the port-city classic
- Norway rat — ground-level, sewer-line, food service
- House mouse — wall voids and garages
Spiders
- Brown recluse — vs. the far more common Southern house spider; ID matters before treatment
- Wolf spider (Lycosidae) — big, fast, and mostly beneficial
Occasional invaders & wildlife
- Silverfish — humidity-driven paper and fabric damage
- Clothes moths — closet and stored-fabric damage
- Moles — lawn tunneling; trapping-based control
- Snakes — identification and humane removal routing
When each pest peaks on the Gulf Coast
Mobile’s mild winters compress the off-season — but pressure still moves in a predictable rhythm.
| Season | What’s active in Mobile & Baldwin County |
|---|---|
| Feb–May | Native subterranean termites swarm in daylight after warm rain; fire ant mounds reappear as soil warms; carpenter ants follow spring moisture into wall voids. |
| May–June | Formosan termite swarms on warm, humid evenings around porch lights — the signature Mobile pest event of the year. |
| Jun–Sep | Peak roach pressure (American, smokybrown, Florida woods); drywood termite swarms; ant trails at their heaviest; storm systems push rodents and wildlife to higher ground. |
| Oct–Jan | Rodent season — roof rats and mice move into attics as nights cool; silverfish and clothes moths show up in closets as indoor humidity shifts. |
After a named storm: flooding pushes ground-nesting colonies, rodents, and wildlife into structures for weeks after landfall. If you’re seeing new activity after a hurricane, see hurricane pest prep and post-hurricane pest control.
Pest identification in Mobile — what do homeowners ask?
Are the operators you route to licensed?
Yes — every operator in the network holds certification from the Alabama Department of Agriculture and Industries (ADAI) under the applicable category: HPC (Household Pest Control), WDO work for termite letters, or fumigation. ADAI licensing is administered under Chapter 28, Title 2, Code of Alabama 1975. You can verify any license by calling ADAI at (334) 240-7240.
Do I need to know the species before I call?
No — species ID is the operator’s first job on site, and it drives the whole treatment plan. But a phone photo of what you saw (even squished, even just droppings or wings) meaningfully speeds up the diagnosis. The library pages above show you what to photograph.
Do you cover my area?
The network covers Mobile County and Baldwin County — Mobile, Daphne, Fairhope, Spanish Fort, Saraland, Theodore, Tillmans Corner, the Eastern Shore, and the coastal communities down to Gulf Shores and Orange Beach. Enter your ZIP in the form above to confirm coverage; see all service areas.
What happens after I submit my ZIP?
Your request routes to an independent, ADAI-licensed operator serving your area. The operator contacts you, inspects, and gives their own quote before any work begins. Availability of same-day and emergency service depends on the provider — it is not guaranteed and varies by demand and location.
Are you the exterminators?
No. Mobile Alabama Exterminators is a free dispatch and referral service, not a pest control company. We connect you with independent, ADAI-licensed operators who perform every inspection and treatment, set their own pricing, and carry their own licensing and insurance.
Which pest does the most damage in Mobile?
The Formosan subterranean termite, without close competition. Mature colonies run into the millions, build carton nests that hold moisture inside walls, and can compress a decade of native-termite damage into two or three years. If you see evening swarms in May or June, treat it as urgent — start at the Formosan termite guide.
