There are so many new types of mouse traps out there! The old standby used to be a spring loaded wire hoop, but those have cheap stamped metal triggers which are difficult to set and I used to use them with a bit of anxiety as I really need my fingers. All of them. You can use sticks or pens to set them, but the best of them are always the most sensitive ones; which means the hardest to set; which means manual dexterity is needed to set them properly; i.e., fingers... so, a difficult choice. So when I browsed ZeeBooth recently and saw so many new types, I was happy to order a couple of each to try them all out. First of all, some of these newer types are vastly superior. I have the 'electric tunnel' one out right now, waiting for a victim... but it seems the ants have found the peanut butter bait first :( And there is the one with a large yellow plastic trigger plate (otherwise same as the old one) but that one, I've had many baits simply stolen; trigger is not sensitive enough. I finally figured out, that with that type you can bend the end of the holding bar that goes into the trigger plate SLIGHTLY downward, this changes the angle that the bar enters the trigger at, and makes it easier to release; a slight bend downward made it vastly more sensitive. (not a recommendation and do this at your OWN RISK) They work good but when you get it sensitive enough, even setting it down the height of one finger's width onto the ground will be enough to trigger it; kinda dicey. There is the type I call the 'chip clip' because it looks like an open jaw, a small black chip clip with a bit of peanut butter inside. Half the time, the mice eat the baits and leave, the trigger is not sensitive enough. The other half of the time the thing closes, but because they are not very powerful, the mice either dodge it or it catches just a small bit of them and they wriggle out. I've had only 1 success with these, of over half a dozen sets, and the animal was still alive and I had to dispatch it. This new type of trap, with 2 bars, has to travel only half the distance to close and has a completely new type of trigger design utilizing several parts arrayed in a cam system. The triggers are fantastically sensitive, yet you never have to touch the bar; and setting it is simple, you can simply put it into place first on the ground, then click the 2nd bar into place, so there is never any danger to your fingers. They appear to be the answer and although I can't use it indoors (pets) it will work fine in the garage. Indoors I use the electronic one. The mass produced triggers, though, seem to have some variance. Although very sensitive, they appear to be a little better in some than others. But these things are so cheap, you can buy a batch and just select the ones with better triggers. Edit/update: OK, I've gone through a couple sets now, and so far they have hit 3 times out of 3! Not a single miss yet. Each one that has been triggered has caught a mouse. No stolen baits yet, at all; pretty impressive! I have several types of traps set out, so after seeing what these can do, I have collected the other traps and dumped them... these Snap-E's will do just fine, thank you.
