I actually mix a little dawn dish soap with mine to help it stick better, put the dawn in last...SB you can get a nice sprayer that actually hooks up to your lawn mower battery for around a 100 bucks ..That's what I got ..I think its a 50 gallon tank and I put it in my lawn trailor and hook up to the battery , its much easier.I don't trust any of this stuff around my family or dogs..I'll just keep doing what I am doing..Interesting info though.
