Let’s do a quick recap of how these devices work.  An electric rat trap consists of two separated metal plates connected to a power supply.  When a rodent steps onto the metal plates it completes an electrical circuit and the sudden power surge kills the rodent.  Instant electrocution via 7000 volts.
Victor® Electronic Rat Trap The Victor® Electronic Rat Trap is the ultimate in rodent control. It works by delivering a humane, high-voltage shock to kill rats that enter the chamber. This powerful device is capable of killing up to 50 rats per set of fully charged batteries (4 “C” included for each trap), making it a great value when you’re dealing with a sizable infestation. It’s also easy to use! To get started, simply apply a high protein bait in the provided bait cup, place the trap in a location with high rodent activity and turn it on.
There are several alternatives to using mouse glue traps. Snap traps work by triggering a mechanism designed to break the mouse’s neck. Though they pose the risk of causing physical injury when tampered with by children and pets, they are inexpensive, can be reused in most cases and quickly trap and kill mice without inhumane drawn-out suffering. If safety is an issue with regard to children or pets, you can even purchase covered snap traps.
Once a rodent triggers the pedal, the rat trap immediately springs closed to eliminate the pest on contact. The rat trap can then be easily disposed of for quick and clean removal. These traps require no chemicals or poisons, so they are safe to use around food, water, children and pets when used as directed. Victor® Easy Set® Rat Traps are perfect for use anywhere in the home. These rat traps should be placed where rodents travel, such as along walls at 2 to 3 foot intervals.
Glue traps never work to keep rodents away in the long run, and their use will actually backfire. This is because when animals are killed or otherwise removed, the resultant spike in the food supply causes accelerated breeding among survivors and newcomers—and this means increased populations. The only surefire way to keep mice and other animals out of your house is to make it less inviting to them.
Is there any way I can get mice out of my room without telling my family? I’m 14 and my room was messy. It might not be my fault but I’ve seen two mice and I’m afraid my family will get mad if I tell them.
DRG suggested using a different bait, one he wouldn’t easily remove. I modified the trigger to make the V-shaped metal tab stick up at a 45º angle. I then formed a ball of cheese around the trigger and reset the trap.
For the final review: If you are killing rats these may work as Ralph was about the size of a large rat. You may want to anchor them to the ground though, and for that I’ll take off one star. If going for larger game, you may want to put a GPS tracking device on these if you wish to get the traps back. As for killing chipmunks, I’d give these traps 1 star as I had a horrible experience and have decided to make a peace treaty with my chipmunk friends instead.
Outstanding product. We had a rat that could set off snap raps and never get caught, escape from glue traps, and was apparently immune to poison. Finally got him with this, thank you Victor!!! We also caught mice in it, not sure why other people say it doesn’t work on them.

Rodents are creatures of habit—they like to take the same path to and from their nests. So your best bet for catching them is to intercept them as they travel back and forth. Target areas near refrigerators, in pantries, along baseboards, or in attic spaces.
Rats are smart and they are inherently cautious.  Kill as many as you can at once before they get wise to your plans.  If the rats figure out how to avoid the traps then you will need to switch to poisons.
