How can I get rid of black ants on my brick patio and cement patio?

I like the ease of a commercial ant trap— both indoors and outdoors. The Terro brand that I have had great sucess with -is recommended quite highly you can check out the reviews and Q&A here— to see if it would meet your needs. I recently set them up a few weeks ago and —problem is once again —solved.

Once you get these traps in place the ant problem is distant memory. They are very effortless, effective and cost-effective. They do not smell badly like an ant aerosol spray does.

I sometimes also use Terro outdoor versions— outside around the foundation perimeter as the ants can be seen under rocks and in my seasonal flowering planters, the do like shade and moisture.

I found this hometalk post very interesting. So interesting that I save it to my bookmarks on my computer. Although I hope I don't need it.

You can try pouring boiling water over them, or try a mixture of vinegar and water, plus hosing down the area as well as you can.

Hi Sir: Make a mix of 1/2 baking soda and 1/2 powdered sugar. Mix well and put around the spots they are in your garden, or inside your home, it's harmless to people and pets. You can put it in a bottle, like a pill bottle or something like that. Cut a hole on the edge of the cap, and lay the bottle on it's side so the ants can come in and get the mix. This way, it stays dry if it should rain. They will take it back to the nest and it should kill them. I'd keep it out there all season if you can. The mix makes a gas and the ants can't pass gas, so it kills them. Anything else that eats it will just taste the baking soda and say "Yuck" and walk off. It won't hurt anything that can pass gas, so it's completely safe. It helps to know what type of ant you are trying to get rid of, too.
