Found one Colorado Potato Beetle when moving a board in the garden. The adults overwinter in the soil, emerge and lay eggs on mostly potatoes but have several hosts. This one adult can lay several hundred eggs and must be suppressed or a potato field is quickly devastated, literally in a few days. I grow less than 100 plants and over the season pick by hand around 2000 eggs and larvae when found on the vegetation. This year I am planting my potatoes late assuming the beetle will have looked elsewhere for a host by the time I plant. Every commercial potato field is heavily sprayed to survive.

I hope you stomped on it and set the carcass on fire!

There was a few years back a biological CPB killer product but for what ever reason they pulled it.

I consider the beetle to be my worst bug. I have only about 100 or less plants and can just destroy all by picking. So far I have voided spraying. I have seen pictures from Minnesota, where they were ankle deep just after spraying and digging the early crop. The bugs migrated to neighbors looking for food.
