Fight back against mosquitoes with the Ortho Home Defense Mosquito Kill & Prevent mosquito station. This innovative device creates an ideal breeding site to attract adult mosquitoes and prevents the development of mosquito larvae into adults. Adult mosquitoes die within nine days after spreading the formula to other breeding sites. Backed by scientific research and available to mosquito professionals, this technology is now available at a DIY price. The active ingredients are contained and targeted, not broadcast into the air. Don't settle for short-term relief from mosquito repellents - this device controls mosquito populations over time for a long-term solution to mosquitoes. You don't need flames, sprays, or batteries, and this station is easy to set up and maintain. To use, simply fill the station with water and place the outdoor mosquito killer in your yard. Attach the refill band to the floater, finish assembling the station, and you're ready to start your mosquito prevention and control. DIY homeowners should replenish water as needed and replace the refill band every month for lasting protection. See label for complete directions. This station controls mosquitoes in an area up to 4,300 sq. ft. and includes 2 refill bands for 2 months of protection. (This product controls Aedes and Culex mosquito species.)
