Like most others, I wouldn't bother with any ants outside, unless they are close to the house or a sitting area or something.
....
- About twice a year, I'll spray all of the known prior entry points as well as doorways, window sills and the house border with Ortho Home Defense. ....
I should comment on "Ortho Home Defense" in the "Superior Products" thread. First, I really hate using pesticides around the house, don't like the smell, possible reactions, and feeling like I need to be so careful with them, but I do what I need to do.
So one day, I'm looking for something for ants in the house. I had used those granules in the past, and there are warnings and it is hard to spread it w/o breathing in some of the dust. Gross!
Then I see the "Ortho Home Defense", and the label warnings are really mild. The label says things like "For pet areas, spray the area, keep the pet away until the surface dries". That's it!
I go home and read up on the active ingredient, it attaches itself to receptors in insects, mammals do not have these receptors, so it seems to have no effect on us.
The official MSDS sheets read like you could probably drink the stuff, and the worst problem would be choking on it.
So I buy it, and
it sprays like water. No smell, not sticky, nothing. But the ants are dead and gone within hours. This stuff really works and appears to be as safe as you can get. And it lasts a long time if not washed away. I sprayed the inside of the garbage can heavily last spring, and all summer long there were no maggots in the can (maggots just gross me out!). Re-apply if you wash the can out.
Yep, this stuff is great. The gallon I bought must be three years old now, maybe older? It goes a long way.
I have not used the Terro traps, I see they get really good reviews on Amazon as w ell, and might be more appropriate in some areas.
