How effective are they in controlling other bothersome insects?
The Pyrethrins act as contact poisonings, immediately affecting the nervous system of the insect. Therefore, they effectively control yards that have large populations of not only mosquitoes, but also other pesky bugs, primarily by killing them. In trace amounts, the chemical will also act as a repellant, helping to keep mosquitoes from entering the targeted areas. Finally, it has been proven, in laboratory testing, that trace amounts of the pyrethrum can also block the female mosquitoes desire to bite, seeking blood protein prior to reproduction..
