Default Re: HELP!! Ants colonized my indoor bananas :nanertank:

Too much is not good, but a little with diatomaceous earth can be lightly dusted over the soil and should not harm the plant. Don't dump it because it does not take much. You can try Terro along the trails first which usually does the trick. I have had colonies in potted plants before and these tricks help control them.
