We also change over the small hive beetle traps we have set (pictured ABOVE) that grate on the top is big enough for the beetles to crawl into the little trough held below it - which is filled with Diatematous Earth, which kills them but not the bees.
We have those in the honey box (the top box) between the frames and another 'mouse' type in the brood box (which is the name for the box on the bottom which contains the larvaes, the Queen and the drones.
We also check to see when and if we need to do a honey harvest too.
Other beetle strategies include having our hives on gravel with weed mat under it (the beetles breed in soil) and also limeing the area around the hives - beetles don't like soil too alkaline (apparently).
But just like designing and maintaining a permaculture garden you need an integrated approach - not just one solution.
Seems to be working though, the number of beetles in our hives were reduced from the last time we checked them.
We're no experts in this, just willing to try different things and keep going with the things that seem to be working.
If you're thinking of getting bees, it pays to join your local beekeeping association and read as many good books as you can on how to care for them.
If this fine weather keeps up, we'll also be able to harvest honey soon too.
