One evening when I walked down to the lower back yard to see how our watermelons, cantaloupes, honeydews, pumpkins and bird nest gourds were doing, I was shocked and a little miffed that all but the pumpkin and gourds were nothing but stems...DARN THOSE GROUND HOGS!!! I came across this and thought that perhaps this would work...and too, I thought that I read in the instructions provided that it would deter rabbits, ground hogs and other rodents...well, no. I ended up purchasing a Havaheart trap and have trapped and released 3 ground hogs, 1 skunk (he was a little guy and cute!) and 1 oppossum and now my mellon patch is thriving...and those plants that were nibbled to just the stems...they've bounced back! So this little contraption is being placed in the garden closer to house...hopefully, it will deter what ever is eating the squash!
