Simply spray the formula on the lizard itself. As Lizards are fast moving cold-blooded animals, it takes a few hours for the formula to take effect on the lizards. An alternative way is to monitor the movements of the lizards and spray the Lizard Exterminator at the affected areas.
Lizard Exterminator acts as a repellent and lizards will naturally avoid the sprayed areas. But if the lizards happen to crawl past these areas, they will die within a few hours.
