Ridding ants in potted plants
Every summer most of my plants go outside.
The last 3-4 yrs, the ant population has increased, ten times higher than ever. Outdoors.
The last few months, I found ants inside indoor pots. Disgusting!
I checked for Scale and other bugs, but didn't see any. So, it's not like Scale is attracting ants..I'm 100% positive, they're crawling in soil when outside.
I was thinking of dumping all old soil, cleaning pots, then adding fresh soil, but once they go outside, the ants will find their way bacl in pots.
What can I do or add so ants stay away? I considered watering (soil) with Rubbing Alcohol and vinegar, but unsure if this concoction will kill roots.
Once plants are outdoors, is there anything I can use that will deter ants.
It's really gotten out of hand; I'm at a loss. What about ant baits? Indoor/outdoor types?
Will rain destroy the baits, even though they can be used outside?
