What is an appropriate treatment for carpenter bees ?
Is the treatment available for residential use or is a professional application required l The bees are damaging wooden fencing and decking?
Answer
In the evening after the bees are home while wearing rubber gloves,mask and goggles (very important) squirt in the hole with Seven or a bee insecticide. Some will flow out but this is why you are wearing gloves. Then immediately stick some brillo pad or similar in the hole, then seal the hole with a type of caulk. Keep an eye out for additional holes and treat them immediately. The larvae are hatching soon! Thanks for contacting PHS. ep
