Product Overview

The Trapper® T-Rex Rat Trap  is a state-of-the-art mechanical trap that offers superior rat capture. Patented interlocking teeth make rat escape virtually impossible. With T-Rex you'll get the perfect combination of trigger sensitivity and trap velocity – speed and responsiveness that ensure a successful and deadly capture. Easy to set and safer to use than traditional snap traps, the T-Rex can be placed directly in a Protecta Rat Bait Station, or tied to pipes or beams that rats may use as highways. A bait cup in the center of the trigger pedal makes it easy to add baits including Bell's new Provoke Rat Attractant.

Manufacturers recommendation: Do NOT use peanut butter in traps as the oil in peanut butter can damage the trap.

    T Rex Rat Trap - Could be improved

    By John on 04/20/2010

    I bought a 12 pack of this trap. The good thing is that they are very easy to set and to release. There are two serious problems. 1 - As others have mentioned, the striking force is much less than a normal old fashioned trap.  I have already had one case of a rat suffering, not dead, even though he was trapped by the head. 2 - The quality is not acceptable. After one use two traps broke. One broke its plastic catch and one broke at the plastic hinge area.

    Sturdy and easy to use

    By Joseph on 11/16/2006

    I like the  Trapper T-Rex Rat Trap very much, it is sturdy and easy to set. Do not use the bait cup included because the rat will just steal it without touching anything. You need to smear some peanut butter on the trigger. Also, the way this trigger is designed, you can adjust it for sensitivity. Basically the way it is the trigger needs to be pushed down almost a quarter inch before it is set off if you just set it and forget it, like this I doubt you will ever catch anything. But if you hold onto the grip and at the same time push the trigger down almost level to the top of the bait dish, just slightly above it where the edge of sensitivity is, I believe you will have better luck with it. Do this after you smeared a thin coat of peanut butter on the trigger and then set it to the edge of sensitivity.

    Easy to use

    By Ken on 11/20/2005

    My Trapper T-Rex trap virtually decapitated a giant wood rat. They are easy to use. Easy to set. Do not get your fingers in this one. I recommend using fishing line to secure the trap to something. If a rat gets a paw stuck in it he will drag it away and you will have to track it down. At $7 each, I don't like hunting my T-Rex. But the rats like them even less.

    Trapper T-Rex Rat Trap

    By Chris on 04/18/2009

    Verified Purchase

    This is by far the best trap I have used. I get the occasional rats from nearby fields and have used the wood traps with limited success in consecutive days. It took one night with the T-Rex Rat Trap. Highly recommended.

    Easy to use and effective

    By Mark on 04/15/2007

    Easy to use and effective. The Trapper T-Rex traps are easier and safer to handle than the conventional spring trap. And they fit (and work) in smaller areas. Peanut butter works great. Like the others, I've learned to secure them in place.

Best way to rid attic in our house of rats?

I don't want to use poison and have rotting rat carcasses in my attic.

The best way to get rid of the rats that are already in your attic is to trap them with rat snap traps, rat glue boards and/or live catch rat traps. We do not recommend using poison baits indoors because after the rats eat the bait they may go into an inaccessible area to die causing a terrible odor and possibly even a secondary insect infestation (it is a myth that there is a poison bait that will cause the rats to dry out and not smell or to leave the house in search of water). It is important that you place the traps directly in the rats travel path and bait them with an attractive bait such as nuts, dog kibble, canned tuna or peanut butter. Be patient, it could take several days or even a couple of weeks before the rats are comfortable enough with the traps to approach them and be captured. After you have eliminated your current infestation you must take the time to exclude rodents from entering your home in the future. Please take a few moments to read our article: How to Rodent Proof Your Home

Can the Trapper T-Rex Rat Trap be used more than once?

Yes, the Trapper T-Rex Rat Trap can be used over and over again.  In fact, once you catch a rat on this trap it will be even more effective because it will have the scent pheromone of a rat which is very curious to other rodents.

Will a rat visit the trap again once it is sprung?
Yes. Often times the pheromone left behind by rodents that have already visited the trap will help draw other rodents to it. Be sure to add fresh bait to help lure the rodents in. If you have a rat that has managed to set off the trap but did not get caught (very rare with the Trapper T-Rex Rat Trap) you may want to disguise the trap a bit to avoid a rat that is trap shy. You can simply place the trap inside of a shoebox with holes cut on either end to allow the rat to enter. This will look different to the rat and the rat will usually not avoid the trap inside.

Smart rats: Can I adjust the sensitivity of a T-Tex Rat Trap trigger?

Last weekend, I placed six pairs of T-Rex traps, baited with Provoke, back-to-back on rat runways in my crawlspace, along with a dozen rat glue traps. Net result: 0 kills/captures, but the bait's been cleaned out twice. These rats are exhibiting a real nuanced touch, and a healthy appetite. Any advice?


The sensitivity cannot be adjusted, but if they are taking the bait and not tripping the Trapper T-Rex Rat Trap then usually this means you are putting too much bait in the bait cup.  You should place only 1 small drop in the bottom of the bait cup so the rodents really have to "get into the cup" and usually this will result in a set trigger.  You can also try a tiny dab of something a little stickier that may result in better results depending on the behavior of the rodents.

Is the rat dead inside the Trapper T-Rex Rat Trap? Is he maimed? How do you dispose of it?
Rats caught in the Trapper T-Rex Rat Trap are usually killed pretty quickly. How you dispose of the rat will vary from region to region, but in most cases you will simply squeeze the trap to release the dead rat directly into a plastic bag, seal the bag and toss in an outdoor trash can.
