I'm a little confused. I thought Ortho home defence for lawn and landscape was used to make a barrier around the foundation of your house to keep the creepie crawlies, like ants, from coming inside.
But, reading the product label, it says you can spray it on your trees and plants and it will kill over 200 types of insects, including bees.
What are you trying to kill? Are you having an insect problem in your trees and plants? If so, I don't think I would use this stuff to do it. Your plants will probably recover. If you sprayed during the day when the sun was out, the leaves got burned. But I suspect this type of insecticide is just too strong to spray on everything in the yard.
I also wouldn't believe the claims that its no longer harmful as soon as it dries. I wouldn't let my dog or kids anywhere near my yard until it was washed thoroughly away.
