I've been using the advantage insect killer from Home Depot with great results, I've seen it kills red bugs too so thats a bonus for preventative Q/T treatments.
I had AEFW in my 400 gallon and BEAT them :clap2: the rotten little acro killing abominations- It required removing every stick from my tank and doing weekly dips but its been 3 months since I have put everything back into the display and I haven't seen a single bite mark or worm. I baste them every so often to see if I see one fly off- knock on wood all has been good so far.
I was lucky for years before I got them, now I Q/T for 4 weeks minimum while dipping weekly and everything gets cut off of what ever it came in on, colony or not.
I loathe those rotten little..........
Edit...the one thing I don't like about advantage is the mixed solution is milky and ai cant see the AEFW come off as I can when I used coralRx, but its cheap and safe
