Small holes in geranium leaves

Asked September 29, 2018, 4:37 PM EDT

I would like to over winter my geraniums which are in pots but noticed small holes in the leaves. I have had these before when I brought geraniums in and later found small worms which I had to pick off. How can I eliminate this problem before bringing them inside and what are they?

Please look up images of Geranium Budworms and see if this is what you have removed from your plants. I suspect that this is what has been eating your geraniums. They are apparently pretty resistant to insecticides, so the recommendation for over wintering plants indoors is to remove the soil they're in and repot with fresh soil.
