Good afternoon. Today I completed your one time service for carpenter bees. Upon arrival you showed me the eaves near back of the house. I observed evidence of carpenter bee activity and nesting between the eaves and side of the house. I applied a liquid treatment to all eaves where evidence was present. Please allow 10 to 14 days for our products to take effect. If after 3 weeks problem still exists. Please give the office a call for a second treatment. Thank you for choosing green pest solutions. Have a great day!
