I over hear:
“I caught some illegal Mexicans honeymooning in my garden! And I took a little knife and squished their heads!”
What?! Ok, ok, I’m listening now I want to see this. Show me the Mexicans in your garden.
I am brought to the green bean plants and am shown the leaves being defoliated
The bean plants do look pretty bad but what about the Mexicans honeymooning?
sure enough under the leaves there they are, Mexican Bean Beetles.
And yellow patches of eggs on the under side of the leaves.
Then I saw for my self the head squishing. And egg squishing.
Moral of the story, growing beans without pesticides means some for you and some for the bugs.
