Pest Control/carpenter bees


My red cedar soffits are being drilled by carpenter bees. The 3rd
floor in very high so difficult work.  Last year I filled in 100 holes
with matched color plastic filler but now there are many bees
driling again. The soffits are coated with Penefin stain.  I have
found permethrin dust to blow into each hole.  I would like to find
a trap to hang from the high soffits to catch the beesbefore they
drill.  Any advice would bee appreciated.  Thanks.


Unfortunately I don't think traps will be effective in this case, see for some additional info and control options. Traps work best if there are only a few bees and even then they have to be placed very carefully. Surface coatings of paint and stain are still the best defence.
