Abstract: An apparatus is disclosed for mosquitoes and other “biting” insects to lay eggs which become trapped before maturing into adults. The trap comprises a reservoir filled with water and divided into two chambers 24 & 26. One chamber 24 is open to the outside at the surface to allow an accessible breeding area. The other chamber 26 is enclosed. Immature mosquitoes fall or are flushed from the open chamber 24 to the enclosed chamber 26, guided along the way by the sloping bottoms of the chambers 20 & 14. A screen, small holes, or similarly restricted exit 40 between the enclosed chamber 26 and the outside chamber 24 allows excess water to escape while retaining most or all of the trapped mosquitoes.
