centipede or millipede infestation
I recently had my landscape mulched, and I'm being invaded by some kind of pede that is about 1.3 inches long and impervious to some common bug sprays. They're also getting into the house.

This sounds like millipedes. We are getting a lot of questions about them due to our wet weather. They are not harmful or poisonous. Here is our website on management inside and outdoors. Focus on cultural control https://extension.umd.edu/hgic/topics/millipedes
