Backyard mosquito control targets vegetation that is a daytime resting site for adult mosquitoes. The objective is to create a lethal insecticide residue on leaf surfaces.
A backpack fogger typically is used to direct a droplet plume to vegetation. Where those droplets go after they leave the nozzle is important, because they may go where they were not intended. Two more fogging tips:
⦁ Residential property lines often have trees and shrubs that serve as “green fences.” They are a standard treatment site. The high (125 to 150 mph) air speed of some backpack foggers can push droplets through vegetation into adjacent property. Some green fences are denser than others, but all the droplets in a plume will not stay within them. Know the distance the droplets will travel from your fogger, and don’t get too close to target vegetation.
⦁ High air speed can affect the residue on targeted leaves. When air carrying the droplets causes the leaves to flutter, droplet deposition and residue decreases. The critical air velocity for flutter is 11 mph; above that there is extreme movement. Over 11 mph, and the insecticide residue will be reduced. Know your machine’s air velocity, and again, don’t get too close to the target vegetation.
