Is my farm a mosquito-breeding site?
Several habitats found on farms can support the production of mosquitoes. Larvae can develop in watering troughs, small ponds, and irrigation ditches, rain barrels, manure lagoons, ruts where farm equipment frequently travels and other areas where water is allowed to accumulate. Even hoof prints can accumulate water and provide a breeding habitat. The close proximity of livestock, nuisance animals (such as birds) and other animals to mosquito breeding habitats increases the risk for the transmission of animal and human disease.
How can I prevent mosquitoes from breeding?
There are many ways to eliminate mosquito-breeding areas on farms. This might include improving drainage in areas that are irrigated, or filling in ruts where farming equipment frequently travels with stones.
Make sure you thoroughly clean watering troughs regularly. Remove or frequently empty any containers that accumulate water, including discarded tires. Aerate small ponds and stock them with fish (Check with the Nebraska Game and Parks Commission to determine which species of fish would be best.)
In situations where eliminating mosquito-breeding areas is not a practical alternative, larvicide is the most effective control technique. Several larvicides are well suited for farms, including Bacillus sphaericus. B. thuringiensis israelensis (B.t.i.), Temephos, growth regulators, oils and mono-molecular films.
A private citizen (farmer or city resident) is able to purchase and apply an general use pesticide product for their private use. That includes any general use larvicide.
Applicators making general or restricted use pesticide applications to control disease vectors (mosquitoes) for political subdivisions must be licensed. A private individual making applications for their personal use falls outside of that interpretation.
An applicator can help you to determine which product would best suit your situation, and what type of control activities should be conducted.
