Mosquito Dunks Mosquito Killer Mosquito Dunks Mosquito Killer is a highly effective biological mosquito control solution designed to eliminate mosquito larvae before they become biting adult mosquitoes. These floating mosquito dunks provide long-lasting treatment for standing water areas such as ponds, birdbaths, rain barrels, gutters, flower pots, livestock troughs, drainage areas, and ornamental water gardens. Each dunk contains a naturally occurring biological larvicide that targets mosquito larvae while remaining safe for people, pets, fish, birds, wildlife, and beneficial insects when used as directed. The active ingredient works by stopping mosquito larvae from developing into adult mosquitoes, helping reduce mosquito populations around homes, farms, recreational areas, and commercial properties. Mosquito Dunks are widely trusted for residential and professional mosquito management programs because they provide continuous control for up to 30 days with minimal maintenance. Simply place the dunk in standing water and allow it to slowly release the biological control agent over time. Key Benefits Feature Benefit Biological Mosquito Control Targets mosquito larvae before they mature into adults Long-Lasting Formula Provides up to 30 days of continuous control Easy-to-Use Dunk Design Simply place in standing water areas Safe Around Wildlife Suitable for use around fish, birds, pets, and wildlife when used properly No Spraying Required Controls mosquitoes directly at the breeding source Effective in Multiple Water Sources Ideal for ponds, birdbaths, gutters, rain barrels, and more Helps Reduce Biting Mosquitoes Interrupts the mosquito life cycle early Environmentally Conscious Solution Uses a biological larvicide instead of broad-spectrum insecticides How Mosquito Dunks Work Mosquito Dunks contain Bacillus thuringiensis israelensis (Bti), a naturally occurring biological bacterium that specifically targets mosquito larvae in standing water. Once mosquito larvae consume the treated water, the biological control agent disrupts their digestive system, preventing them from maturing into adult mosquitoes. Because the active ingredient only affects certain flying insect larvae, it does not harm fish, amphibians, pets, birds, or most beneficial insects when applied according to label directions. Ideal Application Areas Recommended Use Areas Bird baths Rain barrels Decorative ponds Roof gutters Tree holes Water gardens Livestock watering troughs Drainage ditches Flower pots and planters Stagnant standing water areas Product Advantages Advantage Description Preventative Mosquito Control Stops infestations before adult mosquitoes emerge Convenient Slow-Release Action Continues working over an extended period Minimal Maintenance Easy monthly treatment for mosquito breeding sites Broad Area Protection Helps reduce mosquito populations around homes and outdoor spaces Non-Oily Formula Does not create surface film or strong odors Usage Information Place the dunk directly into standing water where mosquitoes breed. One dunk can typically treat up to 100 square feet of surface water. Replace every 30 days for continuous mosquito larvae control.
