Mosquito Control for Gaithersburg's Lakes, Ponds, and Creeks
Gaithersburg has more standing water than almost any suburb in Montgomery County. The 9-acre Rio Washingtonian lake, Lake Helene and Inspiration Lake in Kentlands, Bohrer Park ponds, and stormwater basins across Lakelands, Downtown Crown, Diamond Farms, and Washingtonian Woods all produce mosquitoes from spring through fall. On top of that, Muddy Branch and Great Seneca Creek cut right through residential neighborhoods. Maryland's 44 inches of yearly rain keeps it all wet.
Better Termite & Pest Control has served Montgomery County families since 1968. Our research team removed 9 harsh chemicals common in the pest control industry. We replaced them with reduced-risk products like Essentria and EcoVia. These are products we use in our own backyards, and we bring that same standard to every Gaithersburg home we treat.
Every mosquito plan includes unlimited callbacks at no extra cost. If mosquitoes come back between visits, so do we. No contracts, no hidden fees, no phone trees. Call 703-683-2000 and talk directly with a licensed technician.

How Gaithersburg Mosquito Treatment Works
Every service starts with a property inspection. Your licensed technician maps out breeding sources and resting zones on your lot. In Gaithersburg, that means checking drainage areas near Muddy Branch, pond edges in Kentlands and Lakelands, shaded plants along property lines, and standing water in gutters, bird baths, and landscape features.
During treatment, we use a backpack mist blower to apply a targeted mix of adulticide for immediate knockdown and growth regulator to break the mosquito lifecycle. We focus on shrub lines, deck undersides, eave overhangs, and the thick foliage where mosquitoes rest during the day. We don't blanket-spray your whole yard. We hit the spots that actually hold mosquitoes.
Monthly visits run from April through October. Each treatment builds on the last. Our unlimited callback policy means we come back between visits if activity spikes after a heavy rain or humid stretch along the Muddy Branch or Seneca Creek corridors.
In2Care Traps: Mosquitoes Carry the Treatment for You
In2Care is a great fit for Gaithersburg. With lakes, ponds, and creeks woven through the city, spraying alone can't reach every breeding source. In2Care turns mosquitoes into the delivery system.
We place stations in shaded areas around your property. Egg-laying female mosquitoes are drawn to the water inside, where they contact gauze strips treated with larvicide and a slow-acting fungus. Those mosquitoes then carry the control agents to other water sources they visit. That includes spots along Muddy Branch's wooded edges, the Bohrer Park ponds, and stormwater basins in Lakelands and Crown that no technician could ever walk to.
Why In2Care Works Near Lakes and Streams
- Reaches hidden breeding sites in wetlands and creek corridors beyond your property line
- Targets both adult mosquitoes and developing larvae in a single system
- Works continuously between technician visits without additional spraying
- Pairs with barrier treatments for layered protection throughout the season
Mosquitoes breed in standing water throughout Gaithersburg from April through October
Mosquitoes often rest on screens and exterior walls waiting to enter your home
Monthly barrier treatments from April through October keep Gaithersburg backyards comfortable
Mosquitoes rest in shaded areas during the day and become active at dusk near Gaithersburg creeks and ponds
Perimeter treatments create a protective barrier around Gaithersburg homes
Tick Control for Gaithersburg's Stream Valley Properties
The same green corridors that drive Gaithersburg's mosquito problem also support heavy tick populations. Deer, field mice, and raccoons use the Muddy Branch and Great Seneca Creek valleys to travel between Seneca Creek State Park, Asbury Methodist Village's 17-acre wildlife preserve, and residential backyards. Properties in Washingtonian Woods, Quince Orchard Park, Emory Grove, and the neighborhoods around Malcolm King Park face some of the highest tick exposure in Montgomery County. Lyme disease is a real concern here.
Our tick program uses granular treatments in March and November to target population surges when young ticks carry the greatest risk. From April through October, we spray along the edge where your maintained lawn meets natural areas. This border is where most tick encounters with people and pets actually happen.
Gaithersburg Tick Control Approach
- Spring and fall granular treatments during peak tick activity windows
- Targeted foliar spray along lawn-to-woods transition zones where exposure is highest
- Damminix Tick Tubes that target ticks through the mouse-tick lifecycle
- All products vetted by our research team for reduced environmental impact
Why Gaithersburg Has Such Intense Mosquito Pressure
Three things combine to make Gaithersburg one of the worst mosquito areas in the DC metro. First, permanent lakes and ponds are built into the city. The Rio Washingtonian Center's 9-acre lake, Kentlands' Lake Helene and Inspiration Lake, Bohrer Park's two ponds, Christman Park pond, and Blohm Park pond are just the biggest ones. Add stormwater basins in nearly every planned community and you have breeding habitat on every block.
Second, the Muddy Branch and Great Seneca Creek flow right through residential areas. Muddy Branch starts inside Gaithersburg and runs southwest through stream valley parks to the Potomac. These corridors hold wetlands and slow-moving water that produce mosquitoes well beyond the reach of any yard treatment.
Third, Maryland's humid climate delivers about 44 inches of rain per year. The wettest months line up with peak mosquito season from May through July. Summer highs in the mid-80s with humidity above 70% push the active season well into October. The Asian tiger mosquito is the most aggressive species here. It bites all day long in the shaded, compact lots of Kentlands, Lakelands, Downtown Crown, and Washingtonian Woods. The common house mosquito takes over at dusk, breeding in clogged gutters and retention ponds across the 20877, 20878, and 20879 ZIP codes.
The ongoing Lakeforest Mall demolition and redevelopment is also shifting drainage patterns and pushing wildlife into eastern Gaithersburg neighborhoods. That can temporarily make mosquito breeding worse in areas like Montgomery Village, Flower Hill, and Shady Grove Village.
Seasonal Mosquito Treatment Calendar for Gaithersburg
March: We apply early-season larvicide and granular tick treatments before temperatures hit 50°F and mosquito numbers start climbing. Homes near the Rio lake, Kentlands ponds, or Bohrer Park get the most value from this early start.
April through October: Monthly barrier sprays target foliage, building edges, deck undersides, and shaded resting areas. Each visit builds on the last. During the wettest summer months, we may suggest every-3-week visits for properties along Muddy Branch Creek, near the Washingtonian Woods pond, or next to Seneca Creek State Park.
November: Final granular tick treatment and winterization tips. Reducing overwintering populations now means fewer mosquitoes the following spring.
What Happens After Each Visit
After every visit, we email you a report with what we did, which products we used, and tips for your property. Our unlimited callback policy means we come back between visits if mosquitoes pick up. You never pay extra to get the results you signed up for.
Bundle Mosquito Control with Year-Round Home Protection
Most Gaithersburg homeowners deal with more than just mosquitoes. The same creek corridors and green spaces that feed mosquito populations also bring ticks, ants, spiders, and rodents looking for shelter in your foundation, garage, and walls. Townhome communities in Kentlands, Downtown Crown, and Lakelands face extra pressure from shared walls and common trash areas that give pests easy paths between units.
Our SeasonGuard+ program bundles mosquito control, tick prevention, Sentricon termite monitoring, and general pest control into one monthly plan starting at $95/month. You get 9 visits per year timed around seasonal pest activity, one bill, and unlimited callbacks for every covered pest.
What SeasonGuard+ Includes
- Monthly mosquito barrier sprays from April through October
- Spring and fall granular tick treatments plus Damminix Tick Tubes
- Sentricon termite baiting system with annual inspection
- Coverage for 35 common local pests including ants, spiders, crickets, and mice
- Unlimited callbacks for any covered pest between scheduled visits
What Gaithersburg Area Homeowners Are Saying
1,100+ 5 Star Reviews on Google "We had a bad cockroach problem - we knew it was bad because of all the baby cockroaches we spotted. It took a while but Better Termite ultimately solved it and our house is cockroach free. I signed up for a plan, but ultimately when I got laid off I had to cancel it. Fortunately their customer service, Cindy in particular, was quick to help out and made it pain free"
"I love Darren over at Better Termite. He is always so attentive and kind, and really goes, IMO, out of his way to do a fantastic job. And I am so happy that I had NO MOSQUITOES this summer in my backyard in spite of the fact that there is a drainage area right behind my house, and that is 100% because of Better Termites services."
"I've had nothing but great experiences for 3 years now. Their consistent, reliable service really stands out for me, and everyone is always kind and easy to talk to. I also like that they're a local, family-run business. Kamaal, who I'm gonna call my customer consultant, is fantastic—he really listens to my concerns and works with me to come up with the best plan for whatever pest issues I'm dealing with."
"Better Termite has been keeping our house bug free for years with regular perimeter treatments. As a small, family owned business, they are able to personalize their approach based on your needs. It's clear that they prioritize customer service and communication. We recently had a swarm of a stinging insect take shelter under our ground-level deck, and they researched, bought necessary equipment, and came up with the best way to treat it."
"We have used Better Termite since 1996 and we're very pleased with the results. The techs and the staff are flexible and prompt with appointments. Their price is reasonable. In 2023 we started using their pest control service for bugs and mice. Again we have been happy with the results of their service."
