Why Are Mosquitoes So Bad in Aubrey?
Mosquitoes are so bad in Aubrey because the area has a long warm season, heavy spring and fall rains and still water nearly everywhere. Horse country means stock tanks, water troughs and low pasture spots that hold water for weeks. Add the creeks and wetland edges around Lake Ray Roberts and Lewisville Lake, and mosquitoes never run short of places to breed.

Why Mosquitoes Are Worse Some Years
Weather decides how bad a mosquito year gets. Mosquitoes lay eggs in still water, and the eggs need rain to hatch and warmth to grow fast. A hot summer with regular storms keeps producing new generations. A drought that ends with a burst of rain can be just as bad, because water collects in every ditch, tire and bucket at once.
Mild winters add to it. Around DFW, a rainy stretch that stays at 60°F or above can hatch mosquito eggs in the middle of winter. A warm, wet spell in January can give mosquitoes an early start, so the spring buildup begins before most people think about them.
The kind of mosquito matters too. Denton County Public Health's mosquito facts note that West Nile virus spreads mainly through Culex mosquitoes, which do most of their biting from dusk into the night. The county adds that Culex usually travel 1 to 2 miles to feed, so a pasture pond down the road can supply the mosquitoes on your patio.
What Makes Aubrey Different
People have long called Aubrey horse country, thanks to sandy soil that drew ranchers to the area. That means more stock tanks, troughs, buckets and low spots that hold water than a typical suburb. Each one can raise mosquitoes for weeks if no one changes the water.
Growth adds more. New neighborhoods around Aubrey come with drainage swales, retention ponds and fresh grading, and construction leaves ruts and puddles that stay wet after a storm. The creeks that feed the two big lakes nearby add their own shallow, weedy edges. Open lake water breeds few mosquitoes, but the calm, grassy margins do.
West Nile Activity Around Aubrey
Denton County traps and tests mosquitoes for West Nile virus each season, and it ground-fogs areas when traps come back positive. The county's 2025 fogging maps show two rounds southwest of Aubrey in October, on October 8 and October 17. That's a reminder that West Nile risk in Denton County can run well into fall.
Most people infected with West Nile have no symptoms, but some get very sick. Denton County advises calling a doctor right away for high fever, severe headache, confusion or a stiff neck.
Where Mosquitoes Breed Around an Aubrey Property
Rural and edge-of-town lots have breeding spots that city yards don't. This table lists the common ones around Aubrey and how to deal with each.
| Breeding spot | Why mosquitoes use it | What to do |
|---|---|---|
| Horse and livestock troughs | Still water that sits for days | Dump and scrub small troughs weekly, or keep the water moving |
| Stock tanks and small ponds | Shallow, weedy edges | Keep the edges trimmed and stock mosquito-eating fish |
| Low spots in pastures | Rainwater that stands after storms | Fill or regrade spots that stay wet |
| Tarps on hay, boats and equipment | Folds that trap rainwater | Pull tarps tight or tip them after rain |
| Tires, buckets and feed tubs | Small pockets of warm, dirty water | Drill drain holes, store them upside down or under cover |
| Drainage swales and culverts | Debris that slows the water | Clear leaves and trash so water keeps flowing |
What Helps on a Property This Size
Removing water does the most, but on a few acres you won't reach every source. Mosquitoes also fly in from neighboring properties, so no treatment can wipe them out completely. The honest goal is to cut their numbers down where your family spends time.
Our mosquito control in Aubrey combines yard treatments with MosquitoCon larvicide stations, which we refill every month to stop larvae in water you can't see. The same monthly plan runs across our offices as mosquito treatment for DFW yards.
Aubrey Mosquito FAQ
Why are mosquitoes worse at night?
Culex mosquitoes, the main West Nile carriers in Denton County, bite from dusk through the night. Other species, like the Asian tiger mosquito, bite during the day, so some yards have both shifts.
Do lakes make mosquitoes worse?
Big open lakes breed few mosquitoes, because wind, waves and fish keep the water moving and the larvae eaten. The shallow, grassy edges and the creeks and ponds around the lakes are where the trouble starts.
When does mosquito season end in Aubrey?
There's no fixed end date. Activity drops after the first hard freezes, but any warm, rainy week in winter can bring mosquitoes back for a while.
If mosquitoes are keeping you off the porch this year, price a monthly mosquito plan online or by phone, and we'll set up the stations before the next rain.
