Large roach seen near drains, under refrigerator, or in garage
American cockroaches enter from outside and are most active at night. A single sighting often means there are others.
The Lowcountry Name for American Cockroach
Palmetto Bug Control in Mount Pleasant, SC
Year-round; most activity in warm months (April through October)
Short answer
Palmetto bug is the local Lowcountry term for the American cockroach — a large, reddish-brown roach that lives outdoors in mulch, palmettos, and storm drain systems and moves inside through gaps under doors, around plumbing, and from crawl spaces. They are a different problem from German cockroaches and require a different treatment approach.

Signs to look for
These are the things homeowners spot before they pick up the phone.
Droppings resembling mouse droppings near walls
Larger droppings with blunt ends are from American cockroaches. Mouse droppings have pointed ends.
Egg cases (oothecae) in crawl space or under appliances
Reddish-brown capsules about 3/8 inch long. Finding multiple oothecae indicates an established harborage nearby.
What makes Lowcountry properties attractive to them
The Lowcountry climate is ideal for American cockroaches year-round. Palmetto trees, mulched landscaping beds, and the extensive storm drain system in Mount Pleasant all provide outdoor harborage adjacent to homes.
Pier-and-beam homes and crawl space foundations give American cockroaches direct access from soil to the underside of the home.
Common enough across Charleston County — James Island, Johns Island and West Ashley included.

The look-alike worth ruling out
German cockroach. Palmetto bugs are much larger (1.5-2 inches vs 0.5 inch), reddish-brown vs tan, and are primarily an outdoor pest that enters the home rather than an indoor nesting pest.
How it gets dealt with
Exterior perimeter treatment with a labeled residual
Bait gel application in crawl spaces and garage areas
Entry point sealing around plumbing penetrations and door thresholds
Quarterly exterior maintenance to prevent re-entry
The honest split is simple: contained and caught early is a single visit; recurring outdoor pressure is a plan.
| Your situation | What normally fits |
|---|---|
| Something contained and recent | One-time treatment |
| Outside pressure that comes back each year | Scheduled cover |
| Anything nesting inside the structure itself | Treatment and exclusion |
Before you call anyone
Over-the-counter sprays kill individual roaches on contact but do not address the outdoor population or entry points. A residual exterior treatment and exclusion work is more effective.
Is it a health risk?
American cockroaches carry bacteria and can trigger asthma and allergy symptoms. They are not as significant an indoor allergen as German cockroaches but are still a health concern in active infestations.

Questions & Answers
Frequently Asked Questions
Why do palmetto bugs come inside?
American cockroaches move indoors when outdoor conditions change — heavy rain, drought, or cold snaps drive them to seek shelter. They do not establish indoor colonies the way German cockroaches do; they are primarily outdoor pests that wander in.
Are palmetto bugs the same as cockroaches?
Yes. Palmetto bug is a regional nickname for the American cockroach used throughout coastal South Carolina and Georgia. The name comes from their common outdoor harborage in palmetto palms.
Do palmetto bugs infest the way German roaches do?
No. German cockroaches reproduce extremely rapidly indoors and are a true infestation pest. American cockroaches live primarily outdoors and enter homes individually. The treatments are different.
