temporarily anesthetize honeybees

Asked August 14, 2019, 10:50 PM EDT

Is there a gaseous coolant that can stun / anesthetize bees without toxic effects on either bees or honey?

CO2, when depressurized, would be one non-toxic source with minimal green house gas emission that might stun bees without killing them??

Another item in question is "canned air duster" with : difluoroethane. What I have found so far is :

Any peer reviewed studies?

CO2 is commonly used to anesthetize insects in for various research purposes and also has been used on a limited basis for control in things like stored grain. Its limitation is that it is very slow acting. See Annu Rev Entomol. 2008;53:161-78 and Annu Rev Entomol. 1989;34:97-116.

Smokers are routinely used to make bees docile while working with colonies. You might want to read about that process to see if it meets your needs.

Difluoroethane seems to have good toxicological and environmental profiles, but I found little about its effects on insects.
