Who is Responsible for Mosquito Control?

The best way to eliminate mosquitoes is to eliminate their breeding sites. Residents, businesses, homeowner's associations (HOAs) and municipalities are all responsible for eliminating and preventing mosquito breeding on the property they own, occupy or maintain. 

• Report a mosquito issue at a Gilbert park or facility online through Gilbert 311 or by calling (480) 503-6400 (Monday through Thursday, 7 AM-6PM).
  
  
• Residential areas in Gilbert are NOT included under the town’s mosquito fogging program. If you suspect mosquitos are breeding in an area not maintained by Gilbert, please contact the owner of the property, or Maricopa County Vector Control Hotline at (602) 506-6616.

Read our tips below to see how you can help prevent mosquitoes in your home and neighborhood.

Gilbert Mosquito Control Program

Gilbert's mosquito control program oversees the treatment and elimination of mosquito breeding areas only at its municipal parks, facilities, groundwater recharge and wildlife habitats, and town-operated retention basin areas.

Report a mosquito issue in a public park or facility here. 

Gilbert provides fogging and larvicide treatment applications in these areas only twice per week, from April 1st through October 31st annually. The fogging operations take place during night time hours by certified technicians using a product that is safe around humans and animals.

On those evenings that wind or rain prohibits fogging at the town’s designated treatment areas, the contractor will retry the next evening. If the weather is prohibitive again on that night, the contractor will resume on the next normally scheduled evening.

• The Town of Gilbert is striving to improve the effectiveness of our fogging. To reduce the potential for chemical resistance in mosquitos, Gilbert’s contractor will alternate fogging between EPA approved Zenivex and Kontrol 4-4 or Perm-X UL 4-4.

The following areas are fogged and treated with larvicide: 

• Cosmo Park
• Crossroads Park
• Desert Sky Park
• Discovery Park
• Freestone Park
• Gilbert Regional Park
• Hetchler Soccer Park (Gilbert Youth Soccer Complex)
• Madera Park (Park Improvement District)
• McQueen Park
• Neely Recharge Facility
• Nichols Park
• Riparian Preserve at Water Ranch Recharge Facility
• Spring Meadows (Park Improvement District)
• South Recharge Facility
• Val Vista Park (Park Improvement District)
• Vaughn Retention Basin

Prevent Mosquito Breeding

You can help fight mosquitoes by eliminating their breeding grounds:

• Empty standing water from containers after each rain event
• Adjust your sprinkler timers to allow enough time for grass to dry out before watering again
• Check and eliminate places that accumulate water after irrigating your yard
• Keep fountains operating or drain the water
• Keep swimming pools treated and circulating
• Repair leaky pipes and outside faucets and sprinklers
• Check air conditioning drain hoses to ensure water is not pooling
• Replace your outdoor lights with yellow "bug lights"
• Fill in low spots and level areas within retention basins
• Last, repair and properly maintain dry wells that exist on your property

Chapter III, Regulation 2, of the Maricopa County Health Code states:

"No person shall cause, maintain, or within his control, permit any accumulation of water in which mosquitoes breed or are likely to breed. The owner, occupant, or person in control of any place where mosquitoes are breeding, or which constitutes a breeding place for mosquitoes shall take all necessary and proper steps to eliminate the mosquito breeding and to prevent its recurrence . . ."

What can you do to prevent mosquito bites?

• Use a mosquito repellent according to manufacturer's directions
• Cover up with long sleeved shirts and pants

Are Mosquito Problems Linked to Dry Wells?

A dry well that is not functioning properly can lead to improper drainage and the flooding of the area surrounding the dry well. Gilbert regularly maintains our dry wells.
