Usually when people think about catching rats, they think of the gold standard, the wooden Victor snap trap. They are the least expensive trap normally, and they do kill rats. The newer Victor traps have a large yellow trigger pad which is easier to set than the old all metal traps and can be adjusted for sensitivity.
One of the key strategies in trapping rats is to set out a large number of traps at once. You can visit https://www.allstaranimaltrapping.com/rat-trapping-and-removal/ to know more about animal trapping services.
The wooden snap trap is perfect for this due to it's low cost. There are newer versions of the snap trap such as the Tomcat which are made of plastic. They are easier to set than the wooden traps and more convenient when removing dead rats.
But their cost is noticeably higher than the wooden trap. If price is not an issue, they can be a good way to go especially if setting out just a few traps for just a few rats.
Then there are the rat zappers. This is luxury rat trapping. They are super easy to set. Drop some bait inside and flip a switch. When it comes to removing dead rodents, the zapper has no peer.
You just upend the trap over a container and voila, the rat slides out. No muss, no fuss and a lot less gross. But, the big drawback is the price. They can run from the mid thirty dollar range to the sixty dollar range. That could buy an awful lot of wooden traps. There is no denying their effectiveness and ease of use though.
