Colorado beetle

I found colorado beetle larvae on my potato plants.

I rototilled and used a ruth stout method with gras clipping for my potatoes.

Got 4 rows of 50 feet this way, i noticed about 100 larvae and one adult.

Also i got a lot of ladybugs, spiders and other insects, i hope the ladybugs will feast on eggs and first stage larvae.

I started by collecting with a small broom, i will repeat this daily as i see them.

Also i’m spraying fruit spray, in hopes of making the leaves stronger against sucking insects.

Anyone got experience dealing with this?

I know they got nematodes, but i read they only live for one season.

I dont like to be dependend on one time sollutions bought in a box.
