First of all just for the record there is no insecticide on the market that kills the eggs. Provent a mite is an insecticide with a very long residual effect that will kill the mite larvaes as they hatch within a 30 day period before another application is required .However unlike reptile relief it is not safe for direct application on the snake. That is why people recomend both for a quick and successful erradication. So don't be misled there is an insecticide that kills eggs. That is not how it works.
