No, you are not imagining that constant chirping noise. Cricket are actually INVADING Fresno.
According to this video, these crickets are looking for cool dry places to chill out in this insane heat, and that is why you are finding them in your house, or maybe even in your workplace. Is there a solution? Sorry guys, there's not real way to stop this cricketpocalypse, but you can minimize access to your house by say placing a towel under your door, or making sure there are no ways for them to get in through windows.
But for real guys, these critters are just trying to live like we are. So spare so kindness and just shoo them away, avoid killing them :)
