One of the best products I have found for keeping ants out of my flower pots (and my house) is diatomaceous earth (DE). Just sprinkle a tiny bit around the base of your pots or on the ants' "runs". It won't hurt your plants if you also want to spread a little on the topsoil.
I like DE because it is organic and it is safe. It contains nothing more than the powdered skeletal remains of tiny algae-like plants called diatoms (and maybe some water). DE is considered a mineral-based pesticide. It is made of up magnesium, silicon, calcium, sodium, iron, and several trace minerals. You can find it at garden centers, feed stores, and some health food stores, or order it online. DE is usually sold in 1-2 lb bags and has the look and feel of ground up chalk. I'm not exactly clear whether ants ingest it, or just perish as a result of coming into contact with it, but either way, it dries them up within about 30 minutes of exposure.
Another organic method I've read about is scattering worm casings 1 inch thick across the topsoil of potted plants. Apparently, fire ants (and whiteflies) in particular don't care for this. I have not tried this method personally, but I like the sound of it. You are feeding your plants, while keeping troublesome bugs at bay. If you try it, let me know how it works. You can order worm casings online, get them from worm composters, or find them where organic garden products are sold.

I have a large pot outside with several kinds of plants in it, I just discovered it is full of small black ants. When I moved the pot, the ant "holes" were all under where the pot has been sitting for quiet awhile. Does anyone know how to get rid of these little devils without killing my plants or having to dump the entire pot? Thanks, any help would be appreciated.

Sprinkle in a little cinnamon.
I have had good luck with cinnamon. Just sprinkle it on top of the soil and they should leave.
first I lifted up my plant and was grossed out. I've been spraying with HOT SHOT ant spray, so I soaked the ground with ivory and water then dawn with water and finally cinnamon.
I wouldn't use cinnamon on the soil. I tried that and it killed my plant.
I researched and then made my own insecticidal soap with Dr Bronner's peppermint soap bar. For a 2 gallon potted plant, I cut the bar in half and soaked it outside in a gallon pail of clean water overnite then placed it in the sun for rest of next day. Then I just poured it into my potted plant. Next day I watered it again. Poof they're gone. Plant is happy. Hope it's safe for bees or butterflies getting nectar from the plant though...
I have an ant nest in my rose bush. The bush is planted in a tub. How do a get rid of the ants?
You can use ant bait or spearmint spray.
I am of the anti chemical side so I will tell you what works for me and it is very inexpensive as I can sometimes get it from the dollar store... cinnamon. Plain old pantry cinnamon. Sprinkle it in the dirt. They don't like it and it disrupts their scent paths. You will have to reapply it when it rains and it may take a few treatments.
Good luck! Hope a natural method works for you! It is safe for the plant, pets and kiddos.
I found that Cinnamon powder or Baby powder is a deterrent for ants. Just sprinkle it in the dirt of your planter and they will soon leave !!
so it's tough that it's so near the flower bush because you don't want to upset the plant
but the best way to get rid of an ant's nest I've found is to boil water with orange peels in it, and then douse the nest with it. Instant annihilation, and zero chemicals! If it's impossible due to proximity of rose bush, then probably just something with an insecticide
How do I get rid of ants in the soil of my outside plants on my patio?

I place my plants in a large saucer or tub containing about an inch of soapy water, then flood the potting soil with a soapy-water solution (a little Dawn dishsoap in water). The soapy water will kill the ants, which can't get away because of the water in the saucer/tub. When the ants climb up the pot or up the plant, I spray the soapy water on them. But don't do this in sunlight because it can burn the plants. After the ants are dead, I spray clean water on the plants to remove the soapy water. I've never had a plant die, and I put all my plants out in early spring, each year. Sometimes, I'll water my plants with soapy water just to make sure they don't contain any ants before bringing them in. It's a cheap solution to an aggrevating problem.
