I created some bait hives and used a combo of lemongrass oil and propolis (dissolved in alcohol), and used a small spray bottle to apply it to the inside of a bait box.
The good news is that I caught a swarm (thanks, Phil, for the tutorial!).
The bad news is that the solution destroyed the spray container after a couple of weeks. The container was plastic and had previously had a dilute alcohol solution in it with no problems. The propolis was dissolved in 90% alcohol, so a bit more concentrated.
So my question is, for those using a similar approach, how do you store and dispense your bait?
Thanks,
