I would consider adding some examples of routine "damage" that may be expected. Something like..
"I understand it may be necessary to remove sheetrock, shingles, trim, and other parts of the home in order to fully remove all the bees and foundation and other bee related matter. These holes may be in the living area, the exterior, or the roof, depending on where the bees have colonized. I also understand once the removal is complete, I will have to repair any of these access holes at my own cost."
Also you may want to consider adding..
"I understand some people may be moderately to severely allergic to bee stings. The reactions can vary from mild discomfort to a serious life threatening medical condition. More severe reactions include generalized swelling and itching, faintness, sweating, a pounding headache, stomach cramps or vomiting, a feeling of impending doom, a tight chest or choking sensation with swelling of the throat and in extreme cases anaphylactic shock with death resulting. I understand it is my responsibility to inform all surrounding neighbors so they can take the necessary precautions to protect their family, pets and livestock"
Remember, people are used to having a disclaimer filled with mumbo jumbo. Aslo, you can consider that this is a reminder of exactly how valuable your services are.
BTW, I got the symptoms after a quick google got me here
