I had read an old post that said to use what we call human repellant (urine) on them I had the 3 GS save it in the guest bathroom..they thought that was a hoot but prefered to take care of it on the ant areas. My husband saves and said it save quiet a few flushes every day, lol. We had some ants that came in when it got hot. They would be agt the water faucet outside and all along the side of the house, going up into some plants and making the ground very hard by the house. One time of pouring the human repellant from the faucet and down the house, and off the went to the fence line, lol. OK I know I will be asked so.....collection is in a milk jug with cap and it is tossed each time into the trash. June

OMG. Pee?
Lime and fertilizer will do not help your situation. More likely to do harm. Personally, I would invest in a few boric acid laced ant baits and be done with the problem. You can purchase these liquid baits at any big box, or hardware, or home improvement store. The worker ants (which are all those that you see) swarm the sugary bait, and take every bit of it back to the nest. It is shared with larvae and the queen....resulting in 100% casualty of the nest. Email me if you want name brands.

But, if you reeeallly really WANT to pee all over your yard and deck, GO for it! lolololololol

Had a similar problem last year and tried the new raid sticks you put in the garden or in the lawn. Got about 12, they come in a package of 6 I think. Problem gone in less than a week and haven't had a problem this year.
