Abstract

The present invention provides a humidity tolerant CO 2 generator that operates in combination with an arthropod trap. The CO 2 generator comprises a means for controllably adding solid pellets to an aqueous acid solution, and optionally includes a sound-based counting system for counting the number of pellets dispensed from a feeder reservoir and into a reaction chamber. The invention also provides a method of using the same.

First claim

What is claimed is:

1. A device for generating carbon dioxide as an attractant for biting arthropods in combination with a trap, comprising:
(a.) a reaction chamber charged with an aqueous acid solution when in use;
(b.) a trap for biting arthropods;
(c.) a gas outlet from the reaction chamber connecting between the reaction chamber and the trap for biting arthropods;
(d.) a feeder reservoir containing a plurality of pellets when in use, said pellets comprising a bicarbonate salt;
(e.) means for controllably adding the pellets from the feeder reservoir to the reaction chamber; whereby carbon dioxide is generated in the reaction chamber, passed through the outlet and into the trap for biting arthropods;
(f.) a sound bar;
(g.) a microphone sensor; and
(h.) means for counting the pellets added to the reaction chamber when in use.

2. The device of claim 1 , further comprising:
(i.) a resonant sound board connected to the sound bar; and
(j.) a sound absorbing material surrounding the microphone sensor and the resonant sound board;
wherein, the resonant sound board is physically attached to the sound bar and transfers sound from the sound bar to the microphone sensor; and, wherein the sound absorbing material reduces external noise reaching the microphone sensor.
