Yes & no Ron, you may not see many beetles at all, if any. It maybe only one or two beetles that got a chance to lay some eggs, most likely in drone brood. Or it might be in an area where a lot of drones congregate, baring in mind that drones do no defending. The first time I saw chunks of damaged comb that bees were able to overwhelm on the same day in 2 hives, it was in drone comb on both occasions.
If I find a slime-out, I’ll change the frames as you suggest, however I’ll also change the box, bottom board & lid, because in a slime-out there will be larvae crawling about everywhere. All that slime they produce is a bee repellent, which can cause a colony to eventually abscond if the bees are not able to overwhelm it.
That’s good news that there is less than yesterday.
PS Ron, while waking up & thinking more about it, it just occurred to me that if you were to have a severe slime-out, you would start to see bearding outside the hive before the bees eventually abscond. Therefore while you’re not seeing any bearding, the bees must be successfully rectifying whatever is going on inside the hive.
It was bearding that prompted a Flow hive owner to call me out. He thought I was going to take a split to prevent swarming, when in fact his hive was slimed out a few days after a harvest & the bees were getting ready to abscond.
