Mosquito Barrier is a very strong liquid garlic made from very potent garlic cloves. The juice does not harm humans or pets or plants, but to mosquitoes it can be deadly. Mosquito Barrier, unlike harmful chemicals, doesnt kill bees or butterflies and is completely safe for children, fish, birds, dogs, cats and other pets. Even in the heaviest of infestations the gallon size is almost always enough for the entire year for most homes - including areas where the mosquito is the state bird. Features: It kills the adult mosquitoes on contact. The garlic coated plants keep mosquitoes out of the area. It suffocates any mosquito larvae in standing water, such as puddles. Each quart covers 1.25 acres which is usually enough for a couple applications on smaller properties. This Bundle Also Includes: Chapin 20020 Sure Spray Sprayer 2 Gallon.
