Marathon is a trade name for an imidicloprid.
I don’t think you can get Monitor. You don’t want it. It is highly toxic.
Back when I had a place to garden I lived in the same town as my dad. I would have him come over and do any bug killing. Then I didn’t have to worry about my kids getting into those poisons.
Yes, kids and pets, one reason I don't like my lawn treated. Had to last year. Overkill. Made it worse. Family. Next time I'll do it myself more sparingly and a couple treatments, if necessary.
Have to watch my grandson and neighbor kids though. And if it's too toxic, I don't want any part of it. I think someone came along one side of my house and killed everything with stuff that lasts ten years. Saw the telltale brown crisping on the leaves, then all died. Five years ago, some things try to come back and just too weak. Ticks me off; they would almost have had to come on my property to do it.
Another thing local kids have done for vandalism, but this wasn't that. Sometimes I get so discouraged trying to make my yard look nice on a budget I wonder what's the use, and I can't do as hard work as I was doing past years, winter took its toll on my back and knees.
