Irmo at a Glance

Irmo sits northwest of downtown Columbia, on the ridge between the Broad and Saluda rivers, just off the northern shore of Lake Murray. The town line runs through two counties: part of Irmo is in Richland County and part is in Lexington County. Whichever side of that line you’re on, the steps for getting help are the same.

Irmo began as a small railroad stop and stayed small for decades. Things changed after the interstates came through, and the town grew into the suburb most people know today, with Harbison Boulevard shopping on one side and Lake Murray, Saluda Shoals Park, and Harbison State Forest close by. That mix of established subdivisions, wooded lots, and water nearby shapes a lot of the pest calls homeowners make.

What Irmo Homeowners Tend to Call About

Big roaches coming in from the yard

The large roaches people around here call palmetto bugs are usually American or smokybrown cockroaches. Clemson Extension notes that smokybrown cockroaches like mulch, log piles, thick vegetation, and roof gutters, which describes plenty of shaded Irmo yards. They mostly live outside and wander in, so the fix often starts at the foundation, doors, and gutters. Small tan roaches in the kitchen are a different story. See our cockroach control page for how to tell them apart.

Fire ant mounds in lawns and along driveways

Fire ants are found in every county in South Carolina, and lawns, ball fields, and the edges of driveways are favorite spots for mounds. If you have kids or pets in the yard, it’s worth getting a plan in place rather than kicking at mounds one at a time. Our ant control page covers what a pro typically does.

Termites near damp wood and mulch

Subterranean termites live in the soil and look for moist wood. Clemson’s guidance for homeowners points to the same things again and again: wood touching the ground, thick mulch against siding, crowded shrubs that hold moisture, and gutters that don’t drain away from the house. If any of that sounds like your place, an inspection is a reasonable next step. More on that on our termite control page.

Mice and rats when the weather turns

Rodents look for shelter as nights get cooler. Garages, attics, and gaps where utility lines enter the house are the usual ways in. Our rodent control page explains what a typical visit looks like.

A Simple Seasonal Rhythm for Irmo Yards

• Early spring: watch for winged insects swarming indoors or near windows. Native termites usually swarm in early spring, often in the afternoon.
• Late May to early June: Clemson recommends this window for the spring round of fire ant bait in home lawns.
• Summer: keep gutters clear and pull mulch back from siding, since moisture draws both roaches and termites.
• Late September to early October: the fall round of fire ant bait. In Irmo that lines up with Okra Strut weekend at the end of September, which makes it easy to remember.
• Late fall and winter: check the garage, attic, and crawl space for signs of mice or rats.

A local pro can tell you which of these matter most for your property and what they’d recommend.

Irmo Pest Control Questions

I’m on the Richland County side of Irmo. Can you still help?

Yes. We connect callers on both the Richland and Lexington County sides of Irmo, along with nearby parts of the Dutch Fork and the Lake Murray area. Just tell us your address or zip code when you call.

Is one big roach in the house a sign of an infestation?

Not necessarily. A single large roach often wandered in from outside, especially after rain or on a warm evening. Seeing small roaches in kitchen cabinets, or roaches during the day, is more likely to mean they’re living indoors. Either way, a pro can identify the type and suggest the right approach.
