When it rains hard, does it kill the fleas that are outside?
If you read our FLEA CONTROL ARTICLE, you’ll learn some key yet often times unknown facts about fleas. One of the big ones is that in general, fleas don’t “hang” out in the open like the grass in a yard. What’s most likely out there would be eggs, larvae and pupae. And this would only be true of larvae and pupae if the conditions are right for them to survive past the “egg” stage. As our article explains, these guys need a lot of water, humidity and food to live past the larval stage. Now if they do survive this stage, they’ll then pupate and when ready to hatch, they’ll only do so when a meal is close by so they can jump on it and feed. The key here is that they’ll only hatch out to an adult when food is close by and not because they’re ready to hatch.
