Use CINNAMON!
I am SO SORRY that you are no afraid of insecticides, as if you aren't getting poisoned, also. I was exposed to household stuff, and now I have weird, unexplainable pain. Sometimes it feels like a needle is being pushed into the end of my toe. Sometimes it an unexpected stab of sharpest pain into my leg/hip joint while just walking along, I almost fall sometimes the pain is so sudden and great.
After World War Two, the chemical companies didn't know what to do with their huge stocks of nerve gas, the 'other side' had a lot, also. Some bright guy said, let's add a weakener and sell it for bug spray!
Read the lable, that should scare you.
(off soapbox now)
CINNAMON, what you eat, gets rid of ants. Sprinkle thickly on the surface of the soil, or any surface. Within an hour or so, they will be gone.
Cheers,
Melissa
