I installed this system several years ago. Lots of work every few months to get down on your knees and check every station. Be prepared when you check them with lots of replacement supplies bait station, wood refills and lids that sometimes break. The only reason I didn't give four stars is that I have replaced three Trelona bait units at one station for the last nine months, but the bait stations are filled with termites eating away every time. You would think after three of the poison cartridges they would be dead?
I purchase the Advance Termite Bait system about two months ago and when I checked I found light termite activity in three of the traps so I ordered the Trelona. Unfortunately the next time I looked in the traps they were full of ants who were after the termites. I ordered the ant bait and put that in and the ants are gone so now I'm waiting for the termites to return. I'm gratified that I was seeing termite activity in the traps and am hoping that it will all work out in the end. I will update in another few months.
