The most effective way to control mosquitoes is to stop them from breeding, because a mosquito never travels far from where it hatched. They lay eggs in standing water, and it takes only a bottle cap of it. Dump or drain every bit of standing water you can, drop a larvicide into the water you cannot drain (like drains and low spots), and treat dense shady foliage where adults rest. Do this weekly and you will cut the population far more than fogging ever will.
What you'll need
- A stiff yard brush
- Work gloves
- A rake for leaf litter
- An outdoor oscillating fan for patios
Recommended parts & supplies
- Mosquito dunks (larvicide) — float one in ponds, rain barrels, and low spots that hold water
- Mosquito bits (quick-kill larvicide) — sprinkle in drains, bromeliads, and standing water
- Yard mosquito spray (hose-end) — treat shady shrubs and fence lines where adults rest
- Outdoor patio fan — a steady breeze keeps weak-flying mosquitoes off the patio

Step by step
- 1
Walk the yard and dump every bit of standing water
After a Houston rain, mosquitoes breed in anything that holds water. Walk the whole yard and empty flowerpot saucers, buckets, toys, tarps, trash-can lids, wheelbarrows, and pet bowls. Even a discarded cup matters. Store containers upside down so they cannot refill.
- 2
Clear gutters and check for hidden water
Clogged gutters hold water for days and are a top breeding site people miss. Clear them, then check other stealthy spots: corrugated drain pipe, the base of downspouts, low ruts in the lawn, plant bromeliads that cup water, and the saucer under the AC condensate line.
- 3
Refresh the water you keep
Birdbaths, fountains, and pet bowls are fine as long as the water moves or changes often. Scrub and refill birdbaths at least twice a week to break the mosquito life cycle, and add a small pump or bubbler to fountains so the surface stays disturbed.

Drop larvicide in water you cannot drain
For water you cannot eliminate — rain barrels, ponds, French drains, low spots that stay wet — use a Bti larvicide. Float a mosquito dunk in standing water, or sprinkle mosquito bits into drains and damp low areas. Bti kills the larvae but is safe around people, pets, birds, and fish.
- 5
Treat where adult mosquitoes rest
Adult mosquitoes spend the day resting in cool, shady, humid foliage. Use a hose-end yard spray on the underside of shrub leaves, dense groundcover, tall grass, and along shaded fence lines — not the open lawn. Trim back overgrown vegetation so there is less place for them to hide.

Protect your patio and repeat weekly
On the patio, set up an oscillating fan — mosquitoes are weak fliers and a steady breeze keeps them off you. Then make the water walk a weekly habit, especially after rain. Consistency is everything: skip a couple of weeks in a Houston summer and a new generation is already hatching.
When to call a pro
Call a professional mosquito service if your yard stays swarming despite weekly source reduction, if you have standing water you truly cannot address (a neighbor's lot, a drainage easement, a large pond), or if you want reliable relief for an event or a small child who reacts badly to bites. Pros apply longer-lasting barrier treatments to resting areas and can install an automated misting system. It is also worth a call after a flood, when Houston mosquito populations explode and the disease risk (West Nile, and imported cases) rises — a licensed applicator can knock the population down faster than DIY alone.
