Re: how far will 1 oz of lemon grass oil go when used in trapping swarms?
A very long way. You only want to dip the very tip of a q-tip in the oil and place in a small ziplock bag with a tiny hole punched in the bag. Then place the bag in the swarm box. This will last you for around 30 days. I also place a tiny drop on the outside near the entrance to the swarm box to help them locate it. Check it every 10 days or so to see if you have bees. When you check it, re-apply a tiny drop to the outside again if there isn't any moved in.
Placement is key also. Place the box as high as you can reach in a lone tree located AWAY from a tree line, but close and close proximity to water. This of course is if you are trying to capture away from your bee yard. In your bee yard, place several around to capture your own bees. Good luck!
