Here are the top 3 best mouse traps and how they work.
The Snap Trap
Despite the controversy over killing mice, this is probably the most popular mouse trap out there since it's easy to use and cheap to buy. Another reason why it's so popular is that it kills mice quick so that they don't feel pain, most of the time. When disposing of the mice you should use gloves and clean the area as soon as possible. Vector mouse traps are easy and can be purchased from Amazon.
Kness SNAP-E Mouse
Kness Snap-E Mouse traps are for those who are tired of getting their fingers snapped by the traditional snap trap. It's a little more expensive than the snap trap but it's re-usable which in the long run saves you money. They also made the strike bar a little longer for those bigger mice. I'd personally prefer these traps over the wooden ones mainly because they are re-usable however the downside is that you will have to remove the mouse from the trap.
Agri Zap RZUIR1 Rat Zapper Ultra
This is what you call the top of the line mouse trap. It's mainly used in factories with mice problems. However it can be used for mice invested homes or garages. How the Rat Zapper Ultra works is by luring mice into the trap and then emits an electric shock to instantly kill them. At a round $50 this product is on the pricey end but it does the job well and is re-usable for a long time. There is a chamber that you can detach so that you can easily dispose of the mice once you've caught them. Keep in mind that this mouse trap can hold up to 30 mice, just make sure you clean them out regularly.
