I am sure I have squash beetle on my rhubarb, rainbow chard and raspberries. Is this possible?
Am currently picking them off and stamping on them! Is there a better way to deal with the infestation (and it IS!)

Coreidae is a large family of predominantly sap-sucking insects. You can take the insect to your County Extension Office if you want a specific id of the pest.
Spray the nymphs directly with a ready-to-use insecticidal soap. Spray both sides of the leaves and the stems to ensure you kill all the nymphs feeding on the plants. Repeat every three or four days until you see no more nymphs.
