The bait: Sentricon HD uses Hexaflumuron which is a chitin inhibitor which dries out the outer layer of a termite. Trelona Advanced uses Novaluron which is a chitin inhibitor as well. These baits are like kissing cousins, working the same way to effectively kill termite colonies.
The Station: This is the component that holds, protects, and secures the bait. After installing & monitoring the Sentricon HD system personally in the past, I have found protective caps broken or missing on 2 out of 3 homes, and occasionally the bait missing completely from the station, so this is a very serious drawback to this system and unacceptable. Take into account the Sentricon HD bait stations are only checked once per year by the pest control operator and the risk of bait being exposed freely for a very long period of time go up significantly. If homeowners have small children or pets, this can be a serious risk due to the ease (bait has loop handle to easily grab) at which this bait can be completely removed by a pet or small child. This bait also looks exactly like a rawhide chew for dogs!
