How would you remove gypsy moth caterpillar dropping stains from concrete? The concrete is not painted.

I've never tried to clean them before. My first thought is to use a power washer. I would think that would do it. If that is not an option, maybe a 10% bleach solution might clean it.

Hi Tim,

After I posted my question, I used KRUD KUTTER to pretreat the concrete and then power washed it. Not even that worked. I then read your response days later and thanks so much. I used bleach full strength and it worked. (I used the fresh linen scent though as the regular is over powering).

Great! I'm glad that it worked and I'll remember that if anyone ever asks me again.
