Formulated for professional use, Iguana Scram is a safe yet effective option for eliminating green iguana activity in around flower beds, swimming pools, shrubs and gardens. It's made with a blend of nontoxic, organic ingredients that drive iguanas away with a two-prong approach ... making their food source taste bad and giving the surrounding area a disagreeable smell. These environmental changes disrupt the animals' senses and drive them out of the application zone. Sprinkle or spread liberally to form an 18" barrier around the outside of landscaped areas or a 24" barrier around trees and shrubs. One application provides lasting protection regardless of the season; re-application may be required after periods of extremely heavy rain.
