Last I read, it was fungus gnats, or at least flying bugs.

Ants are different critters.
More than just a nuisance, they "ranch" aphids.
Graze them on our sap so dey can lick dere li'l behinds fo' honeydew.
The nerve!

The good news is;
Ants are easy to thwart.

Here's what I do.

I flower inside, and outside, in 5 gallon DWC buckets.:thumbsup:
About 2/3 way up da bucket, I wrap wide, blue, masking tape.
Then I smear the tape with "Tanglefoot".
Stops all kine malicious buggahs.
'cept da flies.
When a bucket is not in service, I up-end 'em and set ladies in pots of coco on them, like li'l bug-free tables.

Stops crawlies before they evah reach da bottom of da pots.

Safe and sure!

That's my 2 cents on crawlies.

The skinny on gnats will cost ya a nickle, minimum.
Aloha,
Weeze
