G'day,

How long would I have to keep flea eggs and larvae (without the cat) in a freezer to be sure they are dead?

Thank you.
Christina

I can't find any specific info about the length of time at the moment so I'd suggest till they're frozen solid.

Some species of fleas do not mind the cold (although not freezing!) so much - see http://onlinelibrary.wiley.com/doi/10.1 … 374.x/epdf

There are a number of comments about fleas on-line that quote “C.felis has extended its range from into northern temperate climates despite its inability to survive exposures to temperature below 30.2 F (-1 C) for more than five days in any life stage”. The article where this statement is taken can be downloaded from: http://www.researchgate.net/publication … a_Problems

The original reference is: Silverman J, Rust MK. Some abiotic factors affecting the survival of the cat flea, Ctenocephalides felis (Siphonaptera: Pulicidae). Environ. Entomol. 12: 490-495, 1983.
