Thank you for your feedback on your purchase of Ortho Home Defense Mosquito Kill & Prevent Refills. Adult mosquitos that enter the station and are contaminated with the actives will die within 9 days. Because the female mosquito flies away after laying eggs, dead adult mosquitos will not be found in the station. While contaminated adult mosquitos will die within 9 days, this product primarily targets larvae. The larvae may be alive in the station but will die before they mature to adults. To confirm that a station is working you can look for larvae in the water of the station. Larvae in the station may be alive but will die before they mature to adults. A notable reduction in the mosquito population should be seen in 2-3 weeks.

Hi RalphG, we are sorry for any confusion, you will not find dead mosquitoes in your Ortho Home Defense Mosquito Kill & Prevent. Once mosquitos enter the station, they lay their eggs and become contaminated with the dual-action formula. They then exit the station, continuing their natural breeding behavior, and spread the control formula to other breeding sites they visit. Larvae within the station and at the other contaminated breeding sites are killed. If you have any additional questions please do not hesitate to reach out we can be contacted at 888-324-0755.
