Killing thrips with alcohol...?

I have two autos growing in my greenhouse and they both have thrips. Can I kill them with alcohol or would that do damage to the plants? Thanks in advance!

You can, but there's a dilution factor (which I don't know). If not properly diluted it will harm the plants.

OK thanks - I use it full strength when I see pests on my orchids but those are very different from cannabis. According to what I just looked up on google a mixture of 1 part alcohol (70%) to 2 parts water should work. I'll probably dilute the alcohol even more - I can always try a stronger mixture if that doesn't work.
