Who This Is For
This guide is for homeowners who want to reclaim their backyard, families with children who play outside, pet owners concerned about heartworm, and restaurant owners whose outdoor dining suffers from mosquito presence. If you've tried citronella candles and bug sprays with limited success, professional mosquito control offers a reliable solution.
The Problem
Mosquitoes breed in any standing water—from birdbaths to clogged gutters to bottle caps. A single female can lay hundreds of eggs, and under warm conditions, they can become biting adults in just over a week. The peak season runs from late spring through early fall, but in the Deep South, mosquitoes are active year-round. The CDC reports that West Nile virus is now endemic in the continental US, with thousands of cases reported annually. Beyond disease, mosquitoes cause itchy welts and can make outdoor spaces unusable.
Warning Signs
- •Frequent mosquito bites, especially at dawn and dusk
- •Seeing adult mosquitoes resting on walls, under leaves, or in shaded areas
- •Larvae (wrigglers) swimming in standing water like birdbaths, ponds, or rain barrels
- •High-pitched buzzing sounds near ears at night
- •Presence of mosquito eggs—dark, tiny rafts on water surfaces
- •Neighbors reporting similar problems (mosquitoes don't respect property lines)
- •Increased mosquito activity after rain or irrigation
Risks of Waiting
- ⚠Disease transmission: West Nile virus, Eastern equine encephalitis, and dog heartworm
- ⚠Escalating population: One generation can multiply into thousands in weeks
- ⚠Reduced property value: Persistent mosquitoes make yards unusable
- ⚠Legal liability: Restaurant owners may face health code violations or customer complaints
- ⚠Chemical resistance: Delaying treatment can lead to mosquitoes developing resistance to common pesticides

Treatment Options
Barrier Spray Treatment
$70-$150A technician applies a liquid insecticide to vegetation, bushes, and shaded areas where mosquitoes rest. The treatment kills adult mosquitoes on contact and leaves a residual that lasts 3-4 weeks.
Larvicide Treatment
$50-$200Granules or briquettes placed in standing water (ponds, ditches, rain barrels) kill mosquito larvae before they become biting adults. This is a long-term prevention method.
Seasonal Mosquito Plan
$400-$1,200A series of barrier sprays and larvicide treatments scheduled throughout the active season (typically 4-6 treatments). Includes inspection and monitoring.
Mosquito Inspection: What Professionals Look For
A professional mosquito inspection begins outside, examining the entire property for breeding sites. Technicians check gutters, downspouts, low spots in the yard, tree holes, and any container that can hold water. They look for larvae—small, wriggling insects that are visible in clear water. Adult mosquitoes rest in cool, shaded areas like under decking, inside bushes, and on the underside of leaves. A thorough inspection maps these areas to create a targeted treatment plan. Moisture meters and flashlights help find hidden sources. Professionals also assess neighboring properties—if a neighbor has a pond or neglected pool, that can be a source. In some cases, mosquito traps are set to identify species and population density. This data guides the choice of treatment: larvicides for breeding sites, barrier sprays for adult resting areas. Inspection isn't a one-time event. Many companies offer seasonal plans that include periodic re-inspections to catch new breeding sites after rain or landscaping changes. Mosquito Control includes free re-inspections with its service guarantee.
Understanding Mosquito Life Cycles for Better Control
Mosquitoes have four life stages: egg, larva, pupa, and adult. Eggs are laid on or near water and can survive dry conditions for months. Once submerged, they hatch into larvae (wrigglers) within days. Larvae feed on organic matter and molt four times before becoming pupae. Pupae are non-feeding but active; they transform into adults in 2-3 days. The entire cycle can be as short as 7-10 days in warm weather. This rapid cycle is why weekly water removal is critical. Any standing water left for more than a week can produce a new generation. Professionals focus on breaking the cycle at multiple stages: larvicides kill larvae, barrier sprays kill adults, and source reduction removes eggs. Timing treatments to coincide with peak emergence (dawn and dusk) increases effectiveness. Female mosquitoes live up to several weeks and can lay multiple batches of eggs. In northern states, they overwinter as eggs or adults; in the South, breeding continues year-round. Understanding local species helps tailor treatment—for example, Aedes mosquitoes (vector for dengue, Zika) are aggressive daytime biters, while Culex (West Nile vector) feed at dusk.
Are Mosquito Treatments Safe for My Family and Pets?
Professional mosquito treatments use EPA-registered insecticides that are safe when applied according to label directions. Products like pyrethroids (e.g., lambda-cyhalothrin) break down rapidly in sunlight and have low toxicity to mammals. Technicians avoid blooming plants to protect bees, and they apply only to targeted surfaces—not open water where fish or amphibians live. For families with pets, most treatments are safe after the spray has dried (usually 30 minutes to 1 hour). However, cats are sensitive to permethrin; professionals avoid using it near cat areas. Always inform your technician about pets and any beehives on your property. Mosquito Control uses pet-friendly products and offers written warranty terms that vary by provider. Larvicides like Bacillus thuringiensis israelensis (Bti) are bacteria that specifically target mosquito larvae and are harmless to people, pets, and beneficial insects. They are even approved for use in organic farming. For maximum safety, request a treatment plan that prioritizes larvicides and source reduction over broad-spectrum adulticides.

What's your biggest frustration with mosquitoes?
When to Call a Professional
If you have persistent mosquito problems despite removing standing water and using repellents, it's time to call a professional. Also call if you or your family members have experienced mosquito-borne illness symptoms, or if you're planning a major outdoor event. A professional inspection can identify hidden breeding sites and recommend a targeted treatment plan. Mosquito Control offers inspection terms that vary by provider—call 1-888-546-7983 to schedule.
DIY vs Professional
DIY methods like mosquito dunks, sprays, and traps can help reduce populations but rarely eliminate them. The reason: mosquitoes can travel up to a mile from their breeding site, and they breed in places you may not think to check (like corrugated downspout extensions). Professional treatments use EPA-registered products and application techniques that provide longer-lasting control. For most homeowners, a combination of DIY prevention and professional treatment offers the best results.
Local Context
Mosquito control needs vary widely across the US. In the Northeast and Midwest, the season runs from May through September, with peak activity in July and August. West Nile virus is the main concern. Homeowners in these regions often opt for seasonal barrier spray plans. In the Southeast and Gulf Coast, mosquitoes are active year-round, with multiple species including Aedes aegypti (yellow fever mosquito) and Culex quinquefasciatus. Here, larvicide treatments are essential due to frequent rain and high humidity. The Pacific Northwest has fewer mosquito species but sees heavy populations in marshy areas. In the Southwest, mosquitoes breed in irrigation runoff and urban water features; valley fever is an additional concern for outdoor workers. Restaurant owners in any region should consider weekly barrier sprays during peak season to protect outdoor diners.
Prevention Tips
- ✓Empty standing water weekly: flower pots, birdbaths, gutters, toys, and tarps
- ✓Keep grass mowed and shrubs trimmed to reduce resting areas
- ✓Use larvicide dunks in ponds or rain barrels that cannot be emptied
- ✓Install or repair window and door screens (mesh size 18x16 or finer)
- ✓Run fans on patios and decks—mosquitoes are weak fliers
- ✓Treat outdoor clothing and gear with permethrin (safe for adults, not cats)
- ✓Encourage natural predators: bats, purple martins, dragonflies, and goldfish
