Comment on How would you seal this gap under central boiler hydronic baseboard heaters that only get warm, not hot.

  Put down diatomaceous earth or a light dusting of boric acid powder into the crack. Problem solved forever.

    +1 for boric acid. Stuff is a miracle powder.

  Okay then I would fill the gap behind the wall with spray foam first then finish with caulking

    DO NOT PUT SPRAY FOAM ON YOUR BASEBOARD RADIATORS MAN!!! They need service occasionally and you are setting yourself up for an absolute nightmare if you get a leak!!!

      Who said on??? I said in the crack behind the wall. That is why spray foam has a long tube for application. If someone has to go into the wall for service spray foam isn’t going to be a problem.

        You’re absolutely begging for moisture problems if you put spray foam in there. It should be open exactly like it is, albeit cut closer to the way. That really won’t stop bugs anyway, you’re much better off treating the perimeter and plugging exterior access holes.
