Treatment options and typical costs
Property Inspection for Breeding Sites
$0–$150 (often bundled with a first treatment)
Most mosquitoes biting you in Loveland were born within a few hundred feet of your door, so the inspection maps every container, drain, and puddle on the lot. That map becomes the treatment plan.
- Time
- 30–60 minutes
- Best for
- Every yard; finds where mosquitoes actually breed
Source Reduction and Larviciding
$75–$150 per visit
This visit often doubles as homeowner coaching, since most breeding sites on a Loveland lot can be eliminated by hand. A pro points them out so they stay gone.
- Time
- 45–90 minutes
- Best for
- Yards with standing water, clogged gutters, ponds, or drains
Barrier (Residual) Yard Treatment
$75–$200 per visit; $350–$900 per season
Crews should skip blooming plants and vegetable beds when spraying a Loveland property to protect bees and food crops. A careful applicator treats resting cover, not the whole yard.
- Time
- 20–45 minutes per visit, repeated every 3–4 weeks
- Best for
- Shaded yards with shrubs, ivy, and dense landscaping
Misting Systems and In2Care-Style Stations
misting $2,000–$4,500 installed plus refills; stations $200–$500 per season
Stations suit small Loveland lots, townhome yards, and properties where the owner would rather not have spray. They work slowly, so pair them with source reduction.
- Time
- Misting: half a day. Stations: under an hour.
- Best for
- Specific yards: heavy outdoor use or spray-averse owners

First, find and remove the water where they breed. Then spray where the adults rest. Across Loveland, the season runs from about May through September, 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.

A year of mosquitoes in Loveland.
- Winter: fix drainage and store containers upside down. - Spring: dump water and clean gutters before May. - Summer: peak season in Loveland, especially July and August. - Fall: activity fades with cooler nights.
The weekly water walk.
- Tree holes: fill them with sand. - Gutters: clear leaves so water drains. - Saucers and pots: empty them or add sand. - Toys and buckets: store them upside down. - Tarps and covers: pull them tight so water runs off. - Birdbaths: change the water twice a week. - Pet bowls: refresh daily. - AC drip lines and downspouts: make sure water drains away.
Avoiding bites.
- Timing: tiger mosquitoes bite by day; house mosquitoes at dusk. - Repellent: DEET, picaridin, IR3535 or oil of lemon eucalyptus. - 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.
Low-cost ways to cut mosquitoes.
- Lights: yellow bug lights attract fewer insects to the porch. - Mosquito dunks: Bti tablets kill larvae in rain barrels and ponds. - 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.
Mosquito or look-alike?
- Mosquitoes: slim, long legs, and a needle-like mouth. - Crane flies: look like giant mosquitoes. They don’t bite. - Non-biting midges: swarm near water at dusk. Harmless, just annoying. - No-see-ums: tiny biting gnats near marshes. Screens need a finer mesh.
When a bite needs a doctor.
Most people infected with West Nile virus never feel sick. About one in five get a fever, headache or body aches. See a doctor for high fever, stiff neck or confusion. Spreading swelling or an infected-looking bite needs a check too. Most bites just itch for a few days.
Protecting your pets.
Talk to your vet about year-round prevention. Refresh pet water bowls daily; in dry Loveland a bowl or an irrigation puddle is often the only standing water on the block. Keep animals inside until a yard treatment dries. Heartworm reaches dogs through mosquito bites, and cats can get it as well; in Loveland the main exposure runs July through September.
What a treatment visit looks like.
The tech walks the yard first. They dump or treat standing water. Larvicide goes in water you can't drain. Then they spray shady shrubs, where adults rest. Most plans repeat every three to four weeks. A visit usually takes 20 to 45 minutes.
Rain barrels and ponds.
- Pool covers: drain standing water after rain. - Barrels: cover openings with fine mesh. - 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.
Questions to ask before you sign.
- When can kids and pets go back outside? - What product will you spray? - How often will you come? - Do you treat standing water too? - What happens if bites come back between visits? - How do you protect bees and flowers?
