Hi neighbors,<div><br></div><div>Many of my 10+ houseplants are infested with pesky fungus gnats. Does anyone have any left over Gnatrol or Knock-out Gnats (or any other biological insecticide containing Bacillus thuringiensis--BTi)? I thought I&#39;d check with all my fellow gardeners before shelling out $25 for an enormous amount of the stuff! If I end up buying it, I&#39;m happy to share with anyone else who has overwatered their poor plants.</div>
<div><br></div><div>Thanks,</div><div>Laura</div>
