Read the reviews on this trap, then went to Tractor Supply to look at it. It looked so flimsy that I almost didn't buy it. TSC told me if I didn't like it I could return it, so I bought. Other reviewers are correct; yes, the door "springs" are worthless. I found a couple of small springs in my pile of stuff that fit on the doors and kept them closed, but were not too strong to keep the 'munks from entering (see photo). Also, if you are using this trap with just earth or grass underneath, you need to put something under it to keep the critters from burrowing to get the bait. I just cut up the box it came in and used that. I baited it with mixed bird seed, scattering a little bit around the trap.( Chipmunks like lots of different things, but, they LOVE sunflower seed, so why use anything else?) Caught the first one within 15 minutes, emptied, added more seed, left it for a couple more hours and had 3 at once. My total so far is over 40 in about a week. With the additional springs on the doors, they cannot get out. With only the furnished "springs" they can get out, so you will need to be very diligent in emptying the trap if you don't modify it. I guess chipmunks are really stupid- even with one already in the trap, others will go in, I have had as many as 4 at once. Trap is definitely more durable than it looks, I caught a full size brown squirrel and it could not escape and did not damage the trap. Except for the lousy door "springs" I would have given this 5 Stars.

It just doesn’t work. They go in, grab seeds, lift the door and leave. I guess everyone else has dumb chipmunks but mine are smart. I’m hoping I’m able to return. It’s too much money for a trap that hasn’t caught a single chipmunk. I was hoping to avoid a kill trap but I’m out of options.
