Abstract
The present application discloses a system for trapping flying insects, a first chemical lure such as lactic acid, a salt of lactic acid, or combinations thereof, and a second chemical lure comprising a source of ammonia. The lures may be employed in particular geometric shapes contained in specifically designed housing to ensure an effective release rate over extended periods of time.

A device comprising a trap chamber for collecting insects, an inlet communicating with the trap chamber, and an airflow generator constructed to draw air into the trap chamber via the inlet so that insects proximate to the inlet are drawn in the trap chamber;
- and the lure according to claim 1.
A device effective for attracting flying insects comprising a lure according to claim 64 and a carbon dioxide generator capable of generating a gas stream having an elevated level of carbon dioxide at a temperature between ambient and about 140° F.
A device effective for attracting flying insects indoors comprising the lure according to claim 53.
A method for attracting flying insects comprising contacting a source of lactic acid and a source of ammonia with a flow of gas comprising an elevated level of carbon dioxide at a temperature of at least about ambient temperature whereby carbon dioxide, lactic acid and ammonia in amounts effective to attract flying insects towards said sources is caused to flow outwardly from said sources for an extended period and the extended period is at least about one week.
A method for attracting flying insects to a device for capturing flying insects, the method comprising:
- generating a flowing gas stream wherein the gas stream flows outwardly from the device;
- flowing the gas stream in contact with at least one chemical attractant lure for attracting flying insects,
- wherein at least one chemical attractant lure comprises a source of lactic acid and a source of ammonia, whereby at least lactic acid and ammonia are released into the flowing gas stream, and
- at least intermittently continuing the generation of the flowing gas steam for a period of at least about one week, whereby the concentrations of lactic acid and ammonia remain effective to attract flying insects thereto for at least said period.
