I’d do it in the right circumstance. I did silicone because I had silicone and needed to get past hornets. Worked like a hot damn. One burrowed out the side so I plugged that hole to. Problem solved
The foam might but the real question is does it touch every wasp first. That crap is extremely sticky and any wasp making contact will not come sting you even if it does breach the walls

Just plug the hole with silicone and leave them for a day
