Treatment options and typical costs
Property Inspection for Breeding Sites
$0–$150 (often bundled with a first treatment)
Around your Birmingham home, the inspector also checks where adults rest: dense shrubs, ivy, under the deck and along shady fences. Knowing where adults hide shows where barrier spray matters.
- 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 Birmingham 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
Most programs use a pyrethroid spray from a backpack mister. It fades over three to four weeks. Repeat visits keep the coverage up through the season.
- 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 Birmingham 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

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?

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; with about 54 inches of rain a year in Birmingham, bowls and plant saucers refill themselves. Keep animals inside until a yard treatment dries. Heartworm reaches dogs through mosquito bites, and cats can get it as well; Birmingham's season runs roughly May into December, so year-round prevention is the usual advice.
