Gasoline is illegal to use as a pesticide, do I use it no, have I used it, yes I sprayed a little on three hills, I did not pour it then I put a piece of plastic over the hill . The fumes went down and the ants were killed. This was next to my pond and no fish died. Was there a leaching of the gas into the soil, gas vapors yes, raw gas no, the gas evaporates.
Now I would like to explain what happens on the lake south of my place when they have a Bass Masters Tournament. About a hundred boats 200+ HP are leaking raw gas, exhausting oil and fumes into the water. I get a surprise afterwards, theres no dead fish. This is one thing that bothers me, I personally think they need a HP limit on fresh water lakes. They are not going to do that because its fun. I may be wrong so I will keep my mouth shut about that.
Texas has lots of these tournaments because they have some of the best bass fishing in the country. I don't understand that, the lakes have salt, oil, and chemicals in the water, put some of it on the grass and sometimes it will die.
They have fire ants too, and lots of wide open spaces.
Believe me there will be very few Quail left after about four years. Armadillos will take down a few hills for the larva, that's not the answer. Chemicals, Bait or granules is not going to do it. It has not made a dent in them in the past with very powerful, hazardous stuff, even to us so they say . It would kill birds I guess because they have feathers and we don't, bird people would know.
Here's what I think, some animal or insect has got to do it for us, we can only have some control over the fire ants, not all of your neighbors are going to try.
Well I am tired of beating this dead horse. Gnewt
