  • Patent number: 10420345
    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.
