Carpenter Bee Eliminator Kit - The bees can do significant structural damage to wood as seen in photos, I had taken several 2 by 4`s and sawed length ways to see the damage the bees do to lumber and as seen in photos it is quite extensive. The kit you receive includes everything you need to make your own eliminator plus instructions , this is comparable to the solution that was selling on the internet for or more a tube , with this kit you have the ability to make several syringes full . This solution is very effective as you will see. You put a small amount in the hole as seen in photo. The reason this is a kit is due to the fact the EPA will not allow the sale of the premixed solution , but they do allow the sale of the ingredients.
