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!!!
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 wall. That really won’t stop bugs anyway, you’re much better off treating the perimeter and plugging exterior access holes.
My aim is to reduce pests
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.
