its not sprayed on the lawn, I watched the guy spray it who came to the house. He sprayed all the tree trunks, low hanging tree branches and leaves, shrubs, plants, flowers, cedars etc.
I picked up a 2 litre jug of concentrated garlic juice a few years + ago from blue grass, 50$ a bottle.
It worked too well, sprayed in backyard in city and after that I noticed my garden and flowering plants were not doing very well after that..... mosquitos gone and so was everything else, not much pollination happened. Lady bugs gone too... only used for 1 season. I don't know... maybe it was over sprayed? Never really wanted to try again.
