I'm seeing these small, tiny black insects in my basement that look like fleas but aren't. They jump a little bit but there are thousands. I know with fleas you don't see as many. I'm pretty sure these are related to the rainfall we've been having as they only seem to come out when it rains a lot. I think the water is driving them inside. What could they be?
There are many perimeter pests that will invade most any home from the outside and several are small. What you're describing sounds like it could be springtails but I can't be 100% sure without having a specimen to identify. I suggest you review our online SPRINGTAIL CONTROL article to see if this sounds like what you're seeing.
One thing you can do right away that will help would be to install some INSECT MONITORS in any room where you're seeing these guys. Once some are trapped, you can send a board to us so we can learn exactly what you've got and advise you further from that point.
Lastly, you can give our office a call at 1-800-877-7290. One of our tech reps should be able to ask some questions to help narrow down the list and maybe get an idea which it might be. At that point they'll recommend some treatment options.
