Dunks have not been working for me at all. Over 3 months of these little annoying fucks. I've killed spider mites and aphids. Can't get rid of gnats.
I will try gnatrol in addition to dunks.
Gnatrol contains the same bacteria as dunks, just more concentrated, thus preferable.
Dunks/Bits are not live bacteria or viable spores. It's fine in the reservoir unless you drip feed, then use a stocking or such.
They work quite well on a large number of flies, post up a picture in the Infirmary if you need a positive ID.
Hi Lola, if you're still watching this thread, thanks for the post!
I fought FG's for over two years in my houseplants and tried gnatrol, azatrol, DE, skeeter dunks, thuricide, neem oil, sand/gravel caps, pyrethrums and NOTHING worked.
The yellow sticky traps always held dozens of the 'lil fukkerz.
Then I saw this vid by a LDS prepper who claimed 2 tsp. of Dawn Ultra dishwash liquid in 32 oz sprayer filled with water could take out 2" stink bugs on contact.
This recipe actually worked for me and I have been FG free for 5 months.
I sprayed the whole plant until it drips heavily and drench the top of the medium just as heavily.
I'll spray it with plain water after a few minutes to wash it off.
I used this method along with a 2 hour soak w/Dawn to completely submerge the pot of outdoor plants that I want to bring indoors.
This has worked so well for me that I have to share.
This eliminates not only FG's but mites, aphids, etc. BUT it takes out beneficials too.
