The most effective means of reducing mosquitoes around the home is to eliminate their breeding habitats. Nine out of ten citizen inquiries received by Mosquito Control are made by citizens who are unknowingly raising their own mosquitoes! You, too, may be raising your own!
What you can do: CHECK YOUR YARD!
Empty, remove or cover any receptacle that would hold water - particularly old bottles, tin cans, junk and tires
Repair leaky pipes and outside faucets
Screen rain barrels and openings to water tanks and limit the amount of collected rain water to water plants
Cover or turn small boats upside down and keep all water pumped from the bilge
Change water in wading pools, bird baths, pet dishes and vases holding flowers or cuttings twice a week
Clean clogged roof gutters of all debris and drain flat roofs & all tarps
Fill holes in trees with sand or mortar, or drain or spray them as needed
Fix or replace screen on doors and windows
Stock ornamental ponds with mosquito larvae eating fish (call Mosquito Control to make fish delivery arrangements)

Mosquito Control determines where and when to adulticide (spray) based on the following guidelines:
Light traps must contain 25 or more adult mosquitoes/per night/trap
Citizen complaints must be received.
Landing rate counts must exceed 5 mosquitoes landing per minute.
These guidelines are set forth by the Florida Legislature in Florida Statute Chapter 388 and the Florida Administrative Code 5E-13. A light trap is a device that uses dry ice and a light source to attract adult mosquitoes. A fan draws the mosquitoes down into a collection bag. The collection bags are collected every day and the mosquitoes are counted and identified. A landing rate is the number of mosquitoes that land on an individual within a set amount of time (usually one minute).
The Gainesville city limits are divided into 16 adulticiding zones. Mosquito populations are monitored by CDC light traps and landing rate counts Monday through Thursday.
Mosquito Control will insure that the application of pesticides are made only when necessary by determining a need in accordance with specific criteria that demonstrate a potential for a mosquito-borne disease outbreak, or numbers of disease vector mosquitoes sufficient for disease transmission or defined levels of, or a quantifiable increase in numbers of pestiferous mosquitoes as defined by Section 388.011 (4) FS. To determine the need for applications of adulticides, at least two of the following criteria will be met and documented by records:
- When a large population of adult mosquitoes is demonstrated by either a quantifiable increase in, or a sustained elevated, mosquito population level as detected by standard surveillance methods;
- Where adult mosquito populations build to levels exceeding twenty-five (25) mosquitoes per trap night or 5 mosquitoes per trap hours during crepuscular periods;
- When service requests for mosquito control from the public have been confirmed by one or more recognized surveillance methods;
- When counts as determined by normal surveillance methods in the daytime exceed five (5) per minute.
A computerized Ultra-Low-Volume (ULV) sprayer is used to disperse a chemical that affects only adult mosquitoes. The computer measures the chemical and will shut off automatically if the truck is traveling too fast or too slowly or dispersing too much or too little chemical. Spraying is the least effective and most expensive method of mosquito control.
Mosquito Control uses several products with which to adulticide, but Aqua-Reslin and Duet are used for the majority of our routine adulticiding work. Click for more information on Aqua-Reslin and Duet.
Spraying hours are usually between 8:30 pm - 11:00 pm. You may call Mosquito Control at 352-393-8110 for recorded spraying schedule message. The message states in which zone(s) Mosquito Control will be spraying over the next few days.
