A competing system that is quite popular in my area does not have a very good reputation. Despite manufacturer’s claims to the contrary they are apparently prone to clogging within one or two applications of pesticide. That is anecdotal evidence however, I do not have 1st hand knowledge of the apparent issues. See http://www.pestdefense.com/taexx.asp

I’m surprized it is not more common, it is applied where it is needed most, plus it is safer and cleaner.
