The Ovi-Catch is a low-cost, easy-to-use, mosquito surveillance tool proven effective by the U.S. Centers for Disease Control and Prevention (CDC), the company says. The low-maintenance trap does not require electricity or pesticides. It’s designed to capture gravid female mosquitoes looking for a suitable site to lay eggs. Trapped mosquitoes lead to disrupted natural breeding cycles. They indicate the presence of natural, often hidden breeding sites, and allow testing for the presence of disease.
