Wasp Nest in Wall

[Derek Morrison]

Wife was painting and poked a hole thru sheetrock with her finger into a hornets nest in the wall. We had it treated from the exterior a couple months ago and it seems to be inactive, nothing stung her or flew out. All the pest control companies I've called (Central MA) said they don't open sheetrock. Anyone have any contacts they can recommend for this? I don't wanna do it myself in case the nest is still active

Quote from @Jonathan Bock:

Most landlords are reckless and they would do some probing for fun and to save $.  It really is a dangerous business.  

 I'm absolutely horrified of bees/wasps and would gladly pay someone to get rid of it even when it's an old dead nest. I just freeze even seeing that gray paper
