When I bought this I was slightly skeptical, but was willing to try anything. We weren't infested with mice, and had up to this point never even seen a house mouse. But we started to notice one little guy running the length of our hallway at night while we were relaxing on the couch. He was a cutie, but I knew we had to take care of the problem before our one little cutie turned into dozens.I bought this trap due to the great reviews and because I couldn't stand the thought of waking up one morning to find a little dead mouse. We are gentle people, what can I say! Well, the trap got here yesterday, we put it in the hallway up against the wall where we see him run every night, and this morning when I got up there he was! As I write, he is in the trap, unharmed, and we didn't even bait it. I am now going to let him go far away from here, lest he find his way back to this little house with two little boys who inadvertently leave him crumbs everywhere!This trap is amazing. I am going to put it out again tonight just in case we DO have more furries than we realized, but I am almost positive that he is it. This has been so easy, so painless, and really just amazing. I HIGHLY recommend this product!
