What to look for
In summer heat, eggs become biting adults in about a week. Often the source is a neighbor's yard or a storm drain. Mosquitoes breed in standing water, even a bottle cap's worth.

- 2Adults resting under deck boards or in ivy.
- 3A sump pit or crawl space holding water.
- 4Egg rafts floating on stagnant water.
- 5Bites getting worse after each wet spell.

A treatment visit covers the shaded plants and beds where adults rest, along with any standing water that can't be drained.How mosquito treatment works in Frisco.
For Frisco homes, the season runs from about April through October, so a plan usually starts in spring and runs to the end of the season. Larvicide handles water you can't drain, like ponds or drains. Barrier spray covers shady shrubs and leaves. Treatment has two parts. First, find and remove the water where they breed. Then spray where the adults rest.

Avoiding bites.
- Clothing: long sleeves and pants help at dusk. - Fans: a patio fan keeps weak-flying mosquitoes away. - Screens: repair holes in window and door screens. - Timing: tiger mosquitoes bite by day; house mosquitoes at dusk. - Repellent: DEET, picaridin, IR3535 or oil of lemon eucalyptus.
Low-cost ways to cut mosquitoes.
- Mosquito fish: they eat larvae in ornamental ponds. - Pumps and fountains: moving water breeds far fewer mosquitoes. - Trimming: thin out dense shrubs and tall grass. - Lights: yellow bug lights attract fewer insects to the porch. - Mosquito dunks: Bti tablets kill larvae in rain barrels and ponds.
Mosquito or look-alike?
- Non-biting midges: swarm near water at dusk. Harmless, just annoying. - No-see-ums: tiny biting gnats near marshes. Screens need a finer mesh. - Mosquitoes: slim, long legs, and a needle-like mouth. - Crane flies: look like giant mosquitoes. They don’t bite.
When a bite needs a doctor.
About one in five get a fever, headache or body aches. Most people infected with West Nile virus never feel sick. Most bites just itch for a few days. Spreading swelling or an infected-looking bite needs a check too. See a doctor for high fever, stiff neck or confusion.
Protecting your pets.
Ask your vet about year-round heartworm prevention. Cats can too. Dogs get heartworm from mosquito bites. Keep pets inside while a yard spray dries. Change pet water bowls daily.
What a treatment visit looks like.
They dump or treat standing water. The tech walks the yard first. A visit usually takes 20 to 45 minutes. Most plans repeat every three to four weeks. Then they spray shady shrubs, where adults rest. Larvicide goes in water you can't drain.
Rain barrels and ponds.
- Ponds: fish and moving water keep larvae down. - Bird baths: change the water every few days. - Gutters: clear them so water drains away. - Tarps: shake out any that hold rainwater. - Pool covers: drain standing water after rain. - Barrels: cover openings with fine mesh.

What's your biggest concern about mosquitoes?
When to call for help
early in the season, before the first big wave. Ponds, drains and dense shrubs are hard to handle yourself. Call if bites still keep you indoors. Dumping water should come first.
What you can do yourself
A pro adds larvicide for water you can't drain. They also spray where adults rest, every few weeks. The biggest win is free: dump standing water every week. Use repellent and run a fan on the patio.

Questions people ask
What should I do before the pro arrives?
Tell them where you get bitten most. Move toys and pet bowls. Dump standing water.
Is mosquito spraying safe for pets, kids, and bees?
Ask them to avoid flowers. Keep kids and pets inside until it dries. Applied by the label, it's considered low risk once dry.
Can I get rid of mosquitoes permanently?
Removing water and spraying resting spots cuts them down a lot. They fly in from nearby. Not completely.
Will mosquito treatment kill bees and butterflies?
Spraying when bees rest helps too. Ask them to skip blooming plants. It can if spray hits flowers.
Can mosquito control help with West Nile risk?
It can lower it by cutting the number of biting mosquitoes. Repellent and dumping standing water still matter most.
How often does mosquito treatment need to be redone?
For Frisco homes, mosquito control works by removing standing water, treating the water that cannot be drained, and applying barrier treatments where adults rest. For Frisco homes, because they keep breeding through the season, an ongoing plan usually works best.
