This spring, woodpeckers (or a woodpecker) had dug two 4-inch holes into the side of my house. Almost daily, I was jumping to my feet trying to scare them (him) away. When purchasing the two Attack Spider Woodpecker Deterrents, I also purchased two foil octopuses from an online competitor (which I also installed with your useful Screw-up tool since the 15 foot ladder didn’t go up high enough). My first impression was that the competing product would do a better job. I found in practice, however, that although I installed the foil octopuses with very little of the available string, they constantly beat against the house in even mild winds (and although they DID no damage, their tapping was more constant and irritating than the woodpeckers I was hoping to get rid of – moreover, my adobe walls ripped them to shreds in just a few days). While the Attack Spider seemed to be too inconspicuous to work (compared to the other product that only ripped itself to shreds), I’ve only had one initial woodpecker visit since installing the product. The only thing offered by the local Home Depot was a plastic owl (which the salesman acknowledged would likely do nothing) and the only bird to give it any notice was the hawk fearing an invasion into his territory that attacked me as soon as I walked into the back yard with it (like to give me a stroke – LOL). It would be a great service to others if your Attack Spider could replace the plastic owls at hardware stores. My home had previously been attacked by woodpeckers almost daily for months and nothing I did seemed to make any difference. Today, I can again enjoy their presence in my yard without them getting into my house – and they help keep my yard free of bugs! Thank you,
