I’m looking for economical spray for aphids, beetles and cockroaches. The aphids ate all the new growth on my pear and muscadines and the cockroaches were sucking on my raspberries so I need something I can spray on fruit.
For aphids you can power wash them off with the garden hose. That will kill them. Do it a couple days in a row. If you want to stay organic check Captan Jacks Dead Bug Brew. Or you can use Eight a synthetic. On raspberries though bees visit raspberries. It will kill them. Read label to make sure products kill what you want. I know both kill beetles and roaches are beetles.
