Help please,
 
 I manage half a dozen colonies for honey' and fun, and some
friends called who are moving into a house which has an active honey bee
colony in the space between the roof and plasterboard making up the
  raised (cathedral) ceiling.  Its a small, four room house and the bees are
 using both gable end louvered vents for entrance, although they favor one.
 
 This colony has been entrenched for at least three years and many bees
 are clustering on the louvers. The brood nest is approximately 10-15
 feet from  the end of the house in a space hardly larger than the 2x6 inch
 studding.
 
 My friends need to remove or eradicate it.
 
 As there is no access except through the ceiling (the comb is
 approximately midway between the roofline and gutters) they feel they
 will spray the clustering bees on the louvered vents on several
 occasions with soapy water.  When those bees are sufficiently reduced they
 intend to close one vent and severely restrict the other.  They hope
 to find some kind of pesticide dust to place strategically so the
 bees may track it into their nest as they pass through the entrance.
 They are still pondering whether to just allow the wax moths to clean
 up.
 
 Can anyone advise me of a pesticide dust effective in this situation?
 *Instead,* maybe someone could advise me of a beekeeper near Wilmington,
 Delaware who would be willing to take on this task ?  Any
 thoughts would be appreciated.
