Pest Control in Ellicott City, Maryland

Stink bugs on the south wall, mice in the stone basement, ticks along the woods. Give us a call and talk it through.

Ellicott City pest control looks a little different depending on which part of town you're in. Down on Main Street, it's granite walls, damp lower floors and mice that have been finding their way into those buildings for two centuries. Out past Route 29, it's newer colonials and townhouses with fresh mulch, deck boards and a strip of woods out back. The bugs aren't exactly the same, and neither is the fix.

Most calls we get fall into a few groups. Every fall it's stink bugs crowding the siding and slipping into the attic, and right behind them come mice looking for a warm basement. Spring brings carpenter ants in damp sills and, some years, a swarm of winged termites by the basement door that sends people straight to termite treatment. Summer is ticks, mosquitoes and yellow jackets. Whatever it is, an exterminator in Ellicott City who knows these houses will start looking in the right place.

How it works is simple. We answer the phone and connect you with an independent, licensed pest control company that works in Howard County. We don't send out our own trucks, and we'd rather tell you that up front. Inspection, price and the treatment itself all come from the company that shows up at your door. If you aren't sure what you're dealing with, describe it as best you can. A photo on your phone helps.

A Mill Town in a River Valley, With Suburbs All Around It

The Ellicott brothers built their mills on the Patapsco in the 1770s, and the old town still climbs the valley wall the way they laid it out. Main Street runs downhill toward the river and the B&O station, which dates to 1830 and is often called the oldest surviving railroad station in the country. The buildings along it are mostly granite, set right into the rock, with the Tiber and Hudson branches running behind and under them. If you own or rent in the historic district on Main Street, you already know these walls hold onto damp, and damp is what carpenter ants, camel crickets and mice look for first.

Water is part of the story here, and it deserves care. The floods of July 2016 and May 2018 tore through lower Main Street, and a lot of buildings and homes along the branches have been dried out, rebuilt or repaired since. Where wood stayed wet for a while, or a lower floor still runs a little humid, pests can follow. Our guide to old stone foundations walks through what to watch for in older basements, whether yours is on Main Street or a farmhouse foundation out toward Woodstock.

Up out of the valley it changes fast. Dunloggin has 1950s and '60s ranches and capes under big trees. Turf Valley wraps newer homes and townhouses around the golf courses between Route 40 and I-70. Columbia next door has its villages, lakes and paths. All of it sits close to woods, from Patapsco Valley State Park along the river to the stream valleys and parkland in between. That means deer, and deer bring ticks. The Howard County tick guide covers where they hide in a typical yard.

And every fall, the whole county gets stink bugs. Brown marmorated stink bugs head for warm siding in late September and October, and the sunny side of a house in Ellicott City is about as warm as it gets. The big new houses with lots of south-facing glass in Clarksville seem to get the worst of it, but the old Victorians across the river in Catonsville aren't far behind. A week or two after the first frost warning, the mice start looking for a way in, and that's a call we hear from every kind of house in the county.

Why Call Us

• One call instead of five. Skip the voicemail tag with a list of companies. Tell us once what's going on and we'll get you to someone who works your part of the county. The full list of pest services shows what people usually call about.
• We ask what kind of house. A granite building on Main Street and a 2010s townhouse near Route 100 don't get pests the same way. We ask, so the tech isn't walking in blind.
• Honest about who sets the price. We don't quote prices. The company doing the work gives you the number after hearing the details or seeing the place. How a call works.
• Howard County and the edge of Baltimore County. From the historic district out to Clarksville and over the river into Catonsville. See the towns and neighborhoods we cover.
