Treatment options and typical costs
Property Inspection for Breeding Sites
$0–$150 (often bundled with a first treatment)
Most mosquitoes biting you in Suffolk 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
Larvicide works on the stage that cannot fly away, which is why crews in Suffolk treat it as the foundation of any plan. Adult spraying is the follow-up, not the fix.
- Time
- 45–90 minutes
- Best for
- Yards with standing water, clogged gutters, ponds, or drains
Monitoring and Seasonal Plans
$50–$150 per follow-up visit; $350–$900 per season bundled
Ask your pro what happens if bites come back between visits. Many plans include a re-spray within a set window. Ask first.
- Time
- 15–30 minutes per check; season runs spring through first frost
- Best for
- Anyone who wants the yard usable all summer
Barrier (Residual) Yard Treatment
$75–$200 per visit; $350–$900 per season
A barrier treatment coats the undersides of leaves, shrubs, and shaded surfaces where adult mosquitoes rest during the day around your Suffolk home. Adults that land there pick up a lethal dose.
- Time
- 20–45 minutes per visit, repeated every 3–4 weeks
- Best for
- Shaded yards with shrubs, ivy, and dense landscaping
Prices are typical published ranges. Ask what’s included before you compare quotes.

A year of mosquitoes in Suffolk.
- Spring: dump water and clean gutters before May. - Summer: peak season in Suffolk, especially July and August. - Fall: activity fades with cooler nights. - Winter: fix drainage and store containers upside down.
The weekly water walk.
- Tree holes: fill them with sand. - AC drip lines and downspouts: make sure water drains away. - Pet bowls: refresh daily. - Birdbaths: change the water twice a week. - Tarps and covers: pull them tight so water runs off. - Toys and buckets: store them upside down. - Saucers and pots: empty them or add sand. - Gutters: clear leaves so water drains.
Avoiding bites.
- Timing: tiger mosquitoes bite by day; house mosquitoes at dusk. - Screens: repair holes in window and door screens. - Fans: a patio fan keeps weak-flying mosquitoes away. - Clothing: long sleeves and pants help at dusk. - Repellent: DEET, picaridin, IR3535 or oil of lemon eucalyptus.
Low-cost ways to cut mosquitoes.
- Lights: yellow bug lights attract fewer insects to the porch. - Trimming: thin out dense shrubs and tall grass. - Pumps and fountains: moving water breeds far fewer mosquitoes. - Mosquito fish: they eat larvae in ornamental ponds. - Mosquito dunks: Bti tablets kill larvae in rain barrels and ponds.
Mosquito or look-alike?
- Mosquitoes: slim, long legs, and a needle-like mouth. - No-see-ums: tiny biting gnats near marshes. Screens need a finer mesh. - Non-biting midges: swarm near water at dusk. Harmless, just annoying. - Crane flies: look like giant mosquitoes. They don’t bite.
When a bite needs a doctor.
Most bites just itch for a few days. 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.
Protecting your pets.
Heartworm reaches dogs through mosquito bites, and cats can get it as well; Suffolk's June–October season is long enough that most vets advise year-round prevention. Talk to your vet about year-round prevention. Refresh pet water bowls daily; with about 49 inches of rain a year in Suffolk, bowls and plant saucers refill themselves. Keep animals inside until a yard treatment dries.
What a treatment visit looks like.
A visit usually takes 20 to 45 minutes. 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.
Rain barrels and ponds.
- Pool covers: drain standing water after rain. - Tarps: shake out any that hold rainwater. - Gutters: clear them so water drains away. - Bird baths: change the water every few days. - Ponds: fish and moving water keep larvae down. - Barrels: cover openings with fine mesh.
Questions to ask before you sign.
- When can kids and pets go back outside? - How do you protect bees and flowers? - What happens if bites come back between visits? - Do you treat standing water too? - How often will you come? - What product will you spray?
