Understanding Mosquito Biology
Effective mosquito control requires understanding their lifecycle. Mosquitoes have four life stages: egg, larva, pupa, and adult. The first three stages occur in water - making water management the most effective control strategy.
In the Boise area, mosquito season runs from late April through October, with peak activity in June through August. Female mosquitoes (only females bite) need blood meals to produce eggs and can lay 100-300 eggs at a time.
A single female can complete this cycle multiple times during her 2-4 week lifespan, meaning one breeding site in your yard can produce thousands of mosquitoes throughout the season.
Eliminate Standing Water: The #1 Priority
Do a "water walk" around your property weekly. After rain is the best time - you will see exactly where water collects.
Mosquitoes can breed in water as shallow as 1/4 inch. A thorough weekly inspection of your property to eliminate standing water is the single most effective mosquito control measure.
- Plant saucers and pot trays - Empty after rain or watering. Use saucers that drain or add sand to hold moisture without pooling.
- Bird baths - Change water at least twice weekly. Consider adding a small fountain - mosquitoes prefer still water.
- Pet water bowls - Refresh daily. Bring inside or dump at night.
- Children's toys and equipment - Buckets, wagons, playhouses - anything that holds water. Store upside down or covered.
- Tarps and covers - Pool covers, grill covers, and equipment tarps that collect water. Drain after rain.
Often-Overlooked Breeding Sites
These commonly missed water sources can produce thousands of mosquitoes:
- Clogged gutters - Debris-filled gutters hold water for weeks. Clean twice yearly and after storms.
- Corrugated drain pipes - Flexible downspout extensions trap water in ridges.
- Tire swings - Drill drainage holes in the bottom.
- Tree holes and stumps - Fill with sand or mortar.
- Garbage cans and recycling bins - Drill drainage holes in bottoms of outdoor bins.
- Wheelbarrows and garden carts - Store upside down or under cover.
- Boat covers and canoes - Drain water regularly.
Reduce Adult Mosquito Resting Areas
Adult mosquitoes rest during the day in cool, shaded areas with high humidity. Reducing these refuges makes your yard less hospitable.
- Keep grass short - Mow regularly; tall grass provides mosquito shelter.
- Trim shrubs and bushes - Especially lower branches that create dark, humid zones.
- Remove leaf litter - Decaying leaves hold moisture and shelter mosquitoes.
- Clean up yard debris - Piles of branches, grass clippings, and garden waste harbor mosquitoes.
- Increase sun exposure - Prune trees to reduce deep shade. Mosquitoes avoid hot, sunny areas.
Protect Yourself While Outdoors
While working on source reduction, use these strategies to avoid bites:
- Use fans on patios and decks - Mosquitoes are weak fliers. A simple box fan provides significant protection.
- Wear light-colored clothing - Mosquitoes are attracted to dark colors.
- Apply EPA-registered repellents - DEET, picaridin, IR3535, and oil of lemon eucalyptus are proven effective.
- Avoid peak activity times - Dawn and dusk are when most mosquitoes feed.
- Install screens - Ensure all patio/porch screens are intact and properly fitted.
Methods That Do Not Work (Despite Claims)
Be skeptical of products making bold mosquito-eliminating claims. If it sounds too good to be true, it probably is.
Some popular mosquito control products have little scientific support:
- Ultrasonic repellent devices - Studies consistently show no effectiveness against mosquitoes.
- Bug zappers - Kill mostly beneficial insects; studies show they do not reduce mosquito biting rates.
- Citronella plants - The plant itself provides minimal protection.
- Vitamin B supplements - No scientific evidence supports this common claim.
- Banana or garlic consumption - Myths not supported by research.
