Abstract
The present invention provides a humidity tolerant CO2 generator that operates in combination with an arthropod trap. The CO2 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.
Claims2
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.
