Adulticides (Fogging Treatments)

This products targets adult mosquitoes in the evening hours when they are most active and pose the highest risk of biting and disease transmission.

Permasease 4-4

• Use: Applied using truck-mounted ULV (ultra-low volume) foggers to disperse a fine mist that controls flying adult mosquitoes over a wide area.
• Effectiveness: Permethrin is a synthetic pyrethroid that quickly knocks down mosquitoes on contact, while PBO enhances its effectiveness by inhibiting the mosquito's ability to break down the insecticide.
• Safety: Used at extremely low volumes that minimize exposure to people, pets, and wildlife. Permethrin breaks down quickly in sunlight and is approved for use in residential areas.
