Mosquitoes breed in standing water and can ruin outdoor living. The good news: eliminating their breeding sites combined with targeted treatment can reduce mosquito populations by 90% in your yard.

Step-by-Step Elimination Guide

Eliminate standing water

Mosquitoes breed in any standing water — even bottle caps. Empty flower pots, birdbaths, gutters, tarps, and any container holding water. This is the most important step.

Treat water you can't eliminate

Add Mosquito Dunks to ponds, rain barrels, and other water features. BTI larvae control — kills larvae without harming fish, pets, or wildlife.

Apply permethrin yard spray

Spray Martin's Permethrin 10% on all vegetation — grass, shrubs, and low branches. Mosquitoes rest in shade during the day. Treat every 3–4 weeks.

Focus on entry points

Treat patios, under decks, along the fence line, and around the foundation. These are where mosquitoes congregate.

Use fans on patios

Mosquitoes are weak fliers. A box fan pointed outward on your patio reduces bites by 65% according to studies. Simple and effective.

Maintain gutters

Clogged gutters create standing water inches from your home. Clean them twice yearly and consider gutter guards.

Consider a misting system

For serious problems, automated mosquito misting systems can reduce populations by 80%+. Requires initial investment but highly effective.

Frequently Asked Questions

What diseases do mosquitoes carry?

In the US, the main concerns are West Nile Virus and, in some southern states, Eastern Equine Encephalitis. Globally, mosquitoes spread malaria, dengue, Zika, and more.

When are mosquitoes most active?

Dawn and dusk are peak times. On overcast days, they can be active all day. Most species in the US are least active in direct midday sun.

Does citronella actually work?

Citronella candles reduce bites by about 40% within a very limited range. They're a complement, not a solution. Effective yard treatment and eliminating breeding sites are far more impactful.

Is permethrin safe for pets?

Permethrin is safe for dogs but highly toxic to cats. Keep cats off treated areas until dry (about 30 minutes). Never apply permethrin directly to cats.
