Too soon to tell.
Technician (Adam) was very cordial and very professional. Appeared to be quite knowledgeable and thorough.
But, here we are one day later and we have vacuumed up as many live bees/wasps today as we did before the treatment. My tenant ended up sleeping downstairs last night because there were so many bees/wasps in his 2nd floor room.
Let's give it a few more days.
