How effective is adulticiding at reducing the number of adult mosquitoes?
The effectiveness of adulticiding depends on a number of variables that include: which kinds of mosquitoes are present; what chemicals are used; when and how often they are applied; current weather conditions; and the density of homes and streets in a community. It is generally considered an effective means of temporarily reducing adult mosquito populations and has been used in the U.S. and other countries for many years for nuisance reasons and more importantly, as a means of reducing and preventing mosquito-borne disease. The other activities listed above – elimination of breeding sites, education and outreach, and larviciding -precede consideration of adulticide spraying.
