Spectracide Terminate Termite Detection

I purchased three boxes (a total of 45 stakes). Too early to determine if they do the job. I installed these for peace of mind as a preventative measure. I’ve never had any termite issues in the past. I installed all 45 stakes. It was easy and simple to do. I used the little auger tool provided along with my battery powered hand drill. Works great. My only complaint is that out of the 45 stakes, 2 immediately malfunctioned when within 48 hours the red signal rod popped up. It definitely isn’t because of any termite or ant activity or because of excess moisture, etc. I pulled the stakes and they look as new and pristine as when they came out of the box. I called customer support and was told I’d have to remove a box full of stakes (15) of them and return the whole box in order to receive a replacement for the 2 malfunctioning stakes. It just wasn’t worth the effort to remove that many stakes. I would have thought they’d let me return just the 2. They would have easily concurred that it wasn’t and activity issue. I’ll continue to recommend this product as long as I don’t have more malfunctioning stakes.
