Hi Sarah, I’m so sorry to hear about your colony - it’s an ugly sight when wax moths take over! Jeff makes a good point, although I’ve experienced something like what I think you’re describing - please do post pics if you can…anyway, during an end of season inspection I discovered that one of my large & previously strong colonies consisted only of about a hundred workers, desperately trying to remove webs and chase adult wax moths and larvae away, with almost no stores left. It was an awful sight.
My solution was to take the hive away a few feet and put a dish of honey in its place. I gently shook, disentangled and guided all the bees I could over the dish, and they all fell on it eagerly because they were nearly starved. I moved the honey dish right next to the other hive that was on the stand with the infested one, so the now well-fed workers might have a chance to beg their way into it. Thanks to @Dee for that tip
I killed all the moths I could and put the frames into a big bucket of bleach solution to kill the larvae. After that they went into the freezer overnight for good measure, and whatever was less than 50% webbed I cut out and rendered.
The next day, the honey was gone, and so were the bees - I assume that any bees with enough lifespan left in them managed to integrate with the neighboring colony.
Since neither their queen nor any newer brood or eggs were to be found, I figure she must have kicked off in the two and a half weeks or so since my last inspection. That gave the moths the upper hand even though there were still good numbers and activity to my casual eye. The only way I might have had a clue and possibly been able to intervene sooner would have been to heft the hive and realize the weight was dropping. I could have then cleaned up & merged more bees, or bought a mated queen to put with what would’ve been a decent nuc-sized colony or maybe single brood box-worth. It was pretty late in the season, so letting them make a new queen with a frame from another hive would’ve been risky for them and for the other hive.
So, if you have a decent number of bees left WITH a queen, you could clean up and condense the hive. I don’t know where in the world Towradgi is, so I can’t say if you’re at a good point in your season for a population rebound? Or requeening?
Anyway, please let us know more & if you have more questions…
