So, I think it's about time for an update on whether or not spraying a sugar solution on a pasture will indeed grow more grass while also killing the ants in that pasture. My conclusion so far is that it won't control ants at all (I'm not convinced on the growing more grass part either). When I looked at the anthills in the area I sprayed, I didn't notice any reduction at all in the number of ants. Not one to give up unless the going gets too hard, I decided to see if a higher concentration of sugar might work, so I poured about 1 cup of sugar on a single anthill.
Checking back a couple of days later, I still saw a lot of ants going about their ant business (as active as they looked, ant business must be good, and the rat race is a cakewalk compared to the ant race).
So I went back to the ether of the online world and found something that suggested using Borax on ants in the house. I just happened to have a box of Borax (not sure what I had it for, I'll remember what it was for as soon as I pour the last of it on some ants) so I sprinkled it liberally on top of the sugar that I'd poured out on the anthill.
|Just throw some out there and mix it up a little with your foot|
My ant killing pessimism was pretty high at this point, but a day later it looked like only two lethargic ants had managed to drag themselves to work and the ant business that had been booming the previous day had busted overnight.
So my entirely unscientific conclusion is that "maybe" it is possible to kill ants with Borax, or a combination of sugar and Borax. Of course, now I have to figure out if Borax is any better or worse for cattle than if I just used ordinary ant-killer products in a pasture.
