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
