CDC Light Trap: This trap is designed to target adult mosquitoes in search of a host to feed on. It consists of a hanging trap and net. The CDC light trap uses a light and a source of CO2 to attract mosquitoes.
CDC Gravid Trap: Gravid traps are used to collect female mosquitoes that are seeking a water source to lay eggs. The mosquitoes collected in these traps carry the highest risk of being infected with a mosquito borne disease. The trap is a tube with a fan and collection net that sits over a pan of water.
BG Sentinel Trap: This trap is used for Asian tiger (Aedes albopictus) mosquito surveillance. It sits on the ground and uses CO2 and a specially formulated lure to attract mosquitoes looking for a host to feed on.
Source Reduction: The most important and most effective method of mosquito control is source reduction! This means eliminating the water that mosquitoes need to complete their life cycle. If we can reduce the amount of stagnant water, we can reduce the number of mosquito larva that can hatch into adults. Source reduction can be accomplished by turning over containers that hold water, i.e. buckets, flower pots, tarps, toys, pools, tires, and other man made containers. Source reduction is accomplished on a larger scale through maintenance of tidal ditches to remove stoppages that could cause water to pool.
Larvaciding: Water sources that can’t be eliminated can be treated with chemicals that prevent the growth of mosquito larvae. Vector Control uses chemicals that specifically target mosquitoes and minimize harm to other aquatic organisms. Residents of the City of Norfolk can also purchase products that they can use to treat standing water on their property to prevent mosquitoes. Large bodies of water contain natural predators that prevent mosquitoes.
Adulticiding: Ultra-low-volume (ULV) truck mounted sprayers are dispatched to control the adult mosquito population. ULV spraying is conducted based on our surveillance techniques to ensure we are targeting the areas that need adult control. The chemicals are dispensed at a rate that is safe for the environment and citizens but still effective in killing mosquitoes. Vector Control provides a hotline with information on where ULV truck spraying will be taking place in the city of Norfolk at: 757-683-2914.
