I have thousands of grasshoppers (like a plague). They eat the leaves on almost everything - don’t like tomatoes. Any new plants - cukes, beets, carrots, sunflowers, etc coming out of the ground they devour! Have sprayed some with “Sevin”, but don’t like to use chemicals, and so far that doesn’t seem like it does much good, But than again I probably aren’t using enough - I have a large garden. They like the leaves on the raspberries and horseradish too. Any suggestions would be much appreciated. Thank you!
