We recently had an exterminator spray for preventative reasons in the house but the lighted bug traps keeps catching these bugs with antennae and a tail. What are they? Are they harmful to pets or humans? The exterminator said they aren’t fleas. I’ve noticed more of them are in the traps after it rains.

Springtails! Springtails (Collembola) are tiny insects that are extremely common. They are called springtails because of the tail-like appendage that is used to propel them into the air when disturbed. It looks like they jump like a flea, but fleas jump using their rear pair of legs. Springtails "jump" with their tail. They are not known to bite pets nor humans, so they are not a health concern. Weather conditions will drive them into homes, either too wet or too dry. Here is a link to an article about springtails: https://hortnews.extension.iastate.edu/2012/8-15/springtails.html
