If I could give this product 10 starts, I would. It really took care of the chipmunk problem in my front and back yard. It worked the first day I placed it. I was able to capture 17 chipmunks in 10 days.
I had a huge problem with chipmunks in my front and back yard. They dug everywhere and even after replacing the mulch with landscaping stones and thick weed mat, they continued to dig through them. I contracted a green pest control company which put baits all around the house, and after a year, the number of chipmunks just increased. Out of frustration I decided to try these traps. I was initially worried about the hassle of having to trap the chipmunks and not knowing what to do with them. However, after capturing and releasing the first one, it became an easy task.
For about 2/3 of price of a one treatment I was able to buy two cages. The trap captured both small and big chipmunks. On one occasion, though, an animal was devious and ate the bait without triggering the trap. I used peanut butter and topped it with an almond (the cherry on top :). Overall, an easy trap to set and use and highly effective. Well worth the money.
Thank you for this feedback!
