Hi guys,
What's the best thing to use to kill fire ants in large planters?
I put Over 'n Out on my lawn AND in most of the planters, but still the
ants are in some of them. Did I not use enough? (It's one of the
granular 9-month fire ant killers.) I have a jug of Diazinon and prefer
not to use it, but if that's the best option, I will.

TIA,
Cindy
