    Default can i just fill these holes with foam?

    our 20 foot patio has a metal roof.
    where it joins the house are a row of 3" by 3" "holes".

    the wasps love to build nests there.

    You can use bondo to fill the holes. Wasps can chew the foam.

    I think filling holes with foam can be a very bad step.Foam tend to disintegrate very early.So you should search for a better option.

    foam disintegrates when exposed to sunlight but it still takes years. The bondo will shield it from the light/
