Is is necessary to use comb to catch swarms or can one just use foundation. My guess is the queen will want to start laying quickly so comb would be needed. Then on the other hand...swarms don't always find comb when they swarm in nature.
I set up a 10 frame box with some frames and lemongrass oil to see if I could catch a swarm. Though not hopeful I hope to learn from this test at least.
