I don't think in this application a laser would be practical. To kill a mouse you're going to need a really big laser, that would give you 3rd degree burns if you were exposed. I'm not sure you can buy those things if you're not the military and power consumption might be horrendous too.

Shawn Woods on YouTube has a passion for mouse traps. The most effective one is a bucket with a plank, he can catch about 20 mice a night with just one bucket.
