I have an outdoor patio that has a pretty high ceiling and is approximately 15' W X 20' L. I need someone who can spray a mix of water and boric acid (about a 3 to 1 mix) over the interior ceiling of patio to keep the carpenter bees from eating the thing. I have a tall platform latter that should work. Will want the few holes they've already drilled plugged. Prefer someone with experience doing this kind of thing or experienced handyman who can get the job done in timely manner. Shouldn't take more than half a day.
