Females Take Blood Meals
Males do not bite. Adult females take blood meals to develop eggs, then seek suitable egg-laying sites.

Control the Water, the Resting Sites, and the Next Generation
Mosquitoes can interrupt yards, entrances, work areas, and outdoor events. Effective control looks beyond biting adults to find aquatic development and resting sites.
GC Termite Control's primary treatment is a professionally serviced In2Care Mosquito Station program. Inspection may also support source reduction, preventive water treatment, targeted residual liquid, or fogging for short-term adult reduction.
Vegetation, irrigation, neighboring sources, weather, and access shape the recommendation. The goal is a practical, cost-conscious program with monitoring—not instant or permanent elimination.

Egg placement varies by species, but mosquito larvae and pupae develop in water before flying adults emerge.
Day-Biting Near Homes
Local invasive Aedes, often called ankle biters, can use very small indoor or outdoor containers and frequently bite during the day.
Often Active at Dusk or Night
Local Culex mosquitoes are important West Nile virus vectors and commonly become active from evening into the night.
Four-stage lifecycle
Stop Mosquitoes Before the Next Adults Emerge
Development and adult survival vary by species, temperature, water, and food. In warm conditions, container-breeding Aedes can move from egg to adult rapidly, which is why weekly water checks matter.
Egg
Some mosquitoes lay eggs on the water surface. Aedes commonly attach eggs to container walls above the waterline, where they can survive dry periods.
Larva
Larvae hatch when conditions are suitable and live in water, feeding and molting as they grow. These active “wigglers” can often be seen near the surface.
Pupa
Pupae also live in water. They do not feed, but the adult mosquito develops inside before emerging at the water surface.
Adult
After emerging and mating, females seek hosts and egg-laying sites. Rain or irrigation can restart development in overlooked containers.
Why scrubbing matters: Emptying a container removes water and larvae, but Aedes eggs can remain attached to the sides. Scrub the interior before refilling or storing it dry.

In2Care technology
How the In2Care Mosquito Station Works
The station uses the egg-laying behavior of container-breeding Aedes and Culex mosquitoes to reach small breeding sources that can be difficult to find directly.
The Female Enters
A professionally placed station uses water and an odor lure to attract an egg-laying female in a continuously shaded outdoor location.
Two Actives Transfer
She contacts treated gauze carrying the growth regulator pyriproxyfen and the insect-pathogenic fungus Beauveria bassiana strain GHA.
She Leaves the Station
The mosquito is not trapped. She can carry tiny amounts of pyriproxyfen to other container water as she divides eggs among breeding sites.
Adult Emergence Stops
Pyriproxyfen disrupts development so immature mosquitoes in the station and contaminated breeding water do not complete emergence as adults.
The Exposed Adult Dies
The fungal adulticide works slowly. The current EPA label states that contaminated Aedes and Culex adults die within nine days.
It is a dissemination station, not a trap.
Adults leave after contact, so dead mosquitoes generally are not found inside. Visible larvae can occur, but the growth regulator prevents their emergence as adults.

Supporting treatments
Three Tools for Different Mosquito Stages
Inspection determines whether these treatments belong beside an In2Care program. None substitutes for finding and correcting preventable standing water.
Targeted Residual Liquid Spray
A label-permitted residual may target shaded vegetation, leaf undersides, protected eaves, or areas beneath decks. Adults must land on the dried surface.
Product, surface, rain, species, and pressure affect performance. Applications avoid blooms, edible plants, water, toys, and prohibited sites.
Fogging or Space Spray
Fogging uses fine airborne droplets to contact active flying mosquitoes. It can provide rapid, temporary reduction when timing and weather are suitable.
It has little or no residual effect and does not control eggs, larvae, or pupae. It is not long-term prevention or an automatic misting system.
Preventive Water Treatment
When water cannot be dumped, drained, covered, or maintained, an EPA-registered larvicide may fit a label-permitted site. Formulation and reapplication depend on the label.
Bti controls feeding larvae, not adults. Growth regulators such as methoprene or pyriproxyfen prevent adult emergence.
Label-directed service: Sites, weather limits, drift protection, re-entry directions, and precautions vary by product. GC Termite Control follows the selected label rather than applying one treatment everywhere.
Breeding-source field guide
Mosquitoes Do Not Need a Pond
Invasive Aedes can use about one-quarter inch of water. Small containers close to people can be more important than a large, visible body of water.
Plants & Indoor Water
Inspect plant pots and saucers, bromeliads, vases, lucky bamboo, pet bowls, birdbaths, and even a forgotten cup indoors.
Toys, Trash & Decorations
Buckets, toys, open trash or recycling lids, yard decorations, watering cans, and clutter can collect irrigation or rainwater.
Tires, Tarps & Equipment
Tires, folded tarps, wheelbarrows, boats, outdoor furniture, irrigation boxes, and pool covers can conceal shallow standing water.
Rain Barrels & Drainage
Unscreened rain barrels, clogged gutters, downspouts, yard drains, sump areas, puddles, and low soil can retain water long enough for development.
Pools, Ponds & Fountains
Green pools, neglected spas, ornamental ponds, fountains, and poorly maintained circulation systems can become productive breeding sites.
Tree Holes & Landscape Water
Tree holes, dense plant centers, irrigation puddles, leaking fixtures, and other protected depressions can refill repeatedly.
Breeding sites—not nests
Mosquitoes do not build colonies around structures. Immature stages develop in water while adults rest elsewhere, so inspection maps both zones.
Adult resting map
Where Adult Mosquitoes Shelter Between Flights
Adult resting areas help determine where targeted residual treatment may be useful. They are not necessarily the places where larvae are developing.
Dense Shrubs & Groundcover
Thick vegetation, tall grass, and protected groundcover hold shade and humidity close to the property.
Leaf Undersides
Trees and bushes provide protected surfaces where adults can rest away from direct sun and drying wind.
Eaves, Decks & Porches
Undersides of structures, shaded edges, and protected corners can shelter adults close to entrances and seating.
Sheds & Garages
Open or frequently accessed utility spaces can combine shade, stored materials, and nearby human activity.
Patio Furniture
Furniture undersides, covers, and shaded recesses can provide resting surfaces near areas where people spend time.
Moist, Protected Edges
Leaking irrigation, drains, fence lines, and vegetation beside buildings can create sheltered, humid routes.
Inspection directs treatment: Liquid adulticide is not applied automatically. Species, activity, label, blooms, weather, water, occupants, and non-target exposure guide the decision.
Weekly source reduction
Tip, Toss, Scrub, Cover, or Treat
A weekly property check can interrupt development before adults emerge. Combine water management with professional treatment instead of relying on spray alone.
- 01Empty and scrub. Dump container water every week and scrub the sides to remove attached Aedes eggs.
- 02Turn over or discard. Store toys, buckets, tires, wheelbarrows, and containers upside down or remove what is no longer needed.
- 03Cover stored water. Secure rain barrels and water containers with tight lids or mosquito-proof mesh.
- 04Clear drainage. Clean gutters and drains, repair irrigation leaks, and correct low areas that repeatedly hold water.
- 05Maintain water features. Keep pools, spas, ponds, and fountains properly circulated, filtered, sanitized, and free of debris.
- 06Check indoors. Refresh and scrub vases, pet water, plant saucers, and other containers that can support indoor breeding.
- 07Manage vegetation. Thin excessive growth and remove debris that creates humid adult resting areas while protecting healthy landscaping.
- 08Treat only when needed. Use a label-approved larvicide for water that cannot be removed, covered, or properly maintained.
Think beyond the property line: Mosquitoes can arrive from nearby yards, drains, green pools, and shared landscaping. Neighbor participation or County reporting may be needed.
Biological water management
Mosquitofish Have a Limited, Site-Specific Role
Mosquitofish, Gambusia affinis, consume mosquito larvae and may help in suitable permanent artificial water. They are an informational option available through San Diego County, not a substitute for inspection or a treatment that belongs in every container.
Find County mosquitofish guidance →County guidance may allow mosquitofish in artificial ponds, fountains, unmaintained green pools, or animal troughs that can support them.
Do not place them in birdbaths or small containers, and never release them into streams, lakes, natural ponds, or other waterways.
Bite and entry reduction
Protect People While the Control Program Works
Repair Screens and Openings
Repair window and sliding-door screens, install practical door sweeps, and keep unscreened openings closed. These steps reduce indoor exposure but do not control the outdoor population.
Plan for Day and Night Biters
Wear light-colored long sleeves and pants when practical. Patio air movement can also make a seating area less favorable, but it does not remove breeding sources.
Choose an EPA-Registered Repellent
Select a repellent for the person and activity, then follow its label. Because invasive Aedes bite by day, protection should not focus only on dawn and dusk.
GC Termite Control manages mosquito activity but does not diagnose or treat illness. Contact a healthcare provider about concerning symptoms. Report green pools, unusually high neighborhood activity, or public-health concerns through San Diego County Fight the Bite.
Professional process
A Five-Step Mosquito Management Program
The selected tools should respond to the mosquito stages and property conditions actually found—not a fixed treatment package.
Inspect Activity
Review bite timing, appearance, vegetation, water, access, and species clues around the home or business.
Map the Property
Separate aquatic breeding sources from shaded adult resting areas and note sources beyond direct control.
Correct the Water
Remove, scrub, cover, maintain, or directly treat water according to its use and the selected product label.
Deploy the Program
Install In2Care stations and add residual, fogging, or direct larval treatment only when findings warrant it.
Service and Adjust
Maintain stations, monitor evidence, reassess water and vegetation, and adapt recommendations as conditions change.
Rain, heat, irrigation, plant growth, new water, and neighboring sources can change activity after service. Continued source reduction and monitoring remain important.
San Diego health context
Vector Capability Is Not the Same as Local Infection
Not every mosquito species spreads disease, and the presence of a capable vector does not mean that an individual mosquito is infected. Current public-health information matters more than a generic disease list.
West Nile Virus and Culex
West Nile is California's most common serious mosquito-borne disease. Local Culex can acquire it from infected birds and transmit it to people or animals. Risk changes by season and location.
Dengue, Zika, Chikungunya & Yellow Fever
Aedes aegypti and Aedes albopictus can transmit these viruses under the right conditions, but they are not all commonly transmitted in San Diego. Most local dengue cases have been travel-associated, although local acquisition has occurred.
Mosquito control reduces nuisance activity and addresses vector habitat; it does not guarantee disease prevention. Review current information from California Department of Public Health and San Diego County.
Common questions
Mosquito Control FAQ
How does the In2Care Mosquito Station work?
An egg-laying Aedes or Culex female contacts treated gauze, leaves the station, and can transfer pyriproxyfen to other small breeding sources. The growth regulator stops immature development, while Beauveria bassiana slowly kills the exposed adult.
Why does an In2Care station contain water or visible larvae?
Water and an odor lure attract egg-laying females. The station is designed so larvae may be visible before pyriproxyfen prevents them from emerging as adults. Do not open, empty, move, or alter a professionally placed station.
How often are In2Care stations serviced?
The current product label, target species, weather, station activity, and property conditions determine service and water checks. Hot or dry conditions can require additional attention, so one universal interval is not promised.
What is the difference between residual spraying and fogging?
Residual liquid treatment remains on permitted surfaces where resting mosquitoes may land. Fogging uses airborne droplets to contact active flying adults and normally provides short-term knockdown with little or no residual activity.
How much water is enough for mosquitoes to breed?
Invasive Aedes can use approximately one-quarter inch of water. Plant saucers, toy pockets, caps, folds in tarps, drains, and indoor containers can matter even when no pool or pond is nearby.
What should I do with a green pool, pond, or water that cannot be emptied?
Correct circulation, filtration, sanitation, or drainage where possible. A label-approved larvicide or County-guided mosquitofish may fit certain artificial water bodies, but the proper option depends on the site's purpose, size, wildlife, and applicable directions.
