Adulticiding

What is Adulticiding? Adulticiding is controlling mosquitoes in their adult stage.

Adulticides are products that rapidly reduce adult mosquito populations. This can become necessary when larval control measures are insufficient or not feasible. Adulticiding may be initiated when there is evidence of significant populations of mosquitoes in a region, or if there is evidence of mosquito-borne disease transmission in our County.

Spraying the adult flying stage of the mosquito is done when surveillance methods (traps, landing rate counts, inspections) verify that mosquito populations have reached a level to justify the spraying of aerosolized products to control adult mosquito populations. This is usually done by night-time truck spraying.

What you need to know about night-time truck spraying

Adulticide spraying occurs when mosquitoes are most active and when pollinating insects are not active, at night (30 minutes after dusk). Trucks fitted with special spray equipment can be used to treat areas with larvicides or adulticides to kill mosquito larvae or adult mosquitoes. This process is called truck spraying. Truck spraying is used to:

  • Control & reduce the number of mosquitoes that can spread viruses, reducing chances of getting sick.
  • Control and reduce the number of nuisance mosquitoes that bother people but do not spread viruses.
  • Treat entire neighborhoods in a short period of time compared to some other methods.

Mosquito control districts or local government departments track both nuisance mosquitoes and mosquitoes that can spread viruses. Spraying larvicides and adulticides from a truck is one way to kill mosquito larvae or adult mosquitoes in an area. This is especially important when people in a community are getting sick from mosquito bites.

Truck spraying is safe

  • When applied according to label instructions, EPA-registered insecticides do not pose a risk to human health or the environment.
  • If people prefer to stay inside when spraying takes place they can, but it is not necessary.
  • When truck spraying is done correctly, it does not cause asthma attacks.
  • Truck spraying poses minimal risk to pets, animals, and the environment.

There is a possibility that spraying larvicides, like Bti, or adulticides can cause eye irritation if a person is outside when spraying takes place.
