Aerial spraying for mosquitoes in western areas will be attempted on Friday, September 22, 2017  at sunset 

The planned coverage area of approximately 270,000 acres includes all communities west of Military Trail.

 Due to a large mosquito hatch from Hurricane Irma, the Palm Beach County Division of Mosquito Control has conducted several attempts to spray for mosquitoes by helicopter.  Unfortunately the past four attempts have been canceled due to wind speeds that exceeded legal limits for the operation. Should weather conditions prevent spraying, the airspray will occur the first evening weather conditions allow.  To find out if spraying operations were successfully completed, call our AirSpray Hotline for a recorded message at 561-642-8775.

                Aerial spraying is necessary to control the mosquito population that has increased since Hurricane Irma. To further help control mosquitoes, residents are asked to drain or minimize standing water on their properties.

If you are going outdoors after dark, be sure to use an insect repellent containing DEET and wear long pants and a long-sleeve shirt.


Mosquito Control staff are in the field monitoring and applying larvacide to areas of standing water left by Hurricane Irma.


Here are some important things to know and do that will help us in our fight against the bite!

• MOST IMPORTANTLY!!! Homeowners can:

    1. Empty all containers of standing water, including clogged gutters.
    2. Purchase small packets of mosquito larvacide from Home Depot, Lowes or other stores to apply to small areas of standing water that persist for at least a week to ten days.

• The first stage in the mosquito life cycle is as free-swimming larvae. 

• The larvae live in standing water that persists for at least a week to ten days and that does not have fishes to eat the larvae – so not open lakes, etc.

• Over the next week to ten days, we will be out in our trucks applying larvacide to these areas of standing water.

• For those mosquitoes that do emerge as flying, biting adults, we will get most of them by aerial spraying from a helicopter.

• Not all mosquitoes emerge at the same time, so we will time the helicopter spray for the main body of emergence. Therefore, there may be a few days of some hungry mosquitoes before the helicopter goes up.

• The helicopter covers the entire County generally west of Military Trail. Areas east of Military Trail are covered more effectively by use of spray trucks.

  • Night UV Truck Spray

Palm Beach County's warm tropical air and above average rain fall create the perfect environment for insects to multiply. ERM's Mosquito Control staff work hard to enhance the health and quality of life by reducing mosquito populations. Staff use chemical treatment, hormonal and bacterial larvaciding, and biological control methods. Working closely with other agencies like the Health Department, our staff act as first responders to mosquito-borne disease outbreaks as well as coordinate day to day interactions with residents on how to prevent mosquitoes from breeding in their backyard.

There are over 3,000 species of mosquito world-wide. They ALL depend on a source of water to complete their lifecycle.

 Rid the wigglers!

Remove standing water. (old tires, gutters, flat roofs, buckets, drums, other containers)

Cover open containers tightly with a lid or with 16-mesh screen.

Empty plastic wading pools weekly, store indoors when not in use.

Store boats covered or upside down.

Fill in tree holes and hollow stumps that hold water.

Treat bromeliads and other vegetation that hold water with products containing the bacteria Bacillus thuringiensis, var. israelensis.

Stock your ornamental water garden with mosquito-eating fish (e.g. minnows, Gambusia spp., goldfish, or guppies).

Repair screening on windows, doors, porches, and patios.
