Sugar dusted my four foot TBH last Thursday and was not able to drop the bottom board until today. I had the board coated with petroleum jelly to trap anything that fell.
This hive does not like the sugar dust treatment!! I had to back off four times as they covered my veil where I could not see.
All I found was a bunch of pollen and these three worms, maggots or larvae. Can anyone tell me what they are?
Thanks, Robert

SHB larva are smaller, and don't tend to be in small numbers. If there's one, there's usually a hundred.

Wax moth, you can sometimes find a lone larva.

Any treatment that I can do, or let the bees handle it?
This hive is pretty crowded and they are defensive. Only one of the larvae was alive, the rest were dead.
Thanks, Robert

wax worm larva. if the hive is strong and packed there is not much more you can do, it is not unusual to find a stray larva or two in a hive where a wax moth sneaked in and got a few eggs laid before she was escorted out. If your hives were low on numbers that they could not cover comb (foundation does not count since the larva will not attack it to much of an extent) you can install an entrance reducer. Once you find SHB larva in a hive it is a down hill slide for the most part.

a few is likely not much to worry about. with wax worms large numbers or trash being hauled out the front door is another matter. I would guess the three wax worms (the black one is approaching death) were dislodge from between box layers in that small and often uneven gap between top bar and bottom bars. active bees will seal them in there and any shuffling of frames or box layer will dislodge them.

ps... my mistake you said you had a tbh.

Wax moth and small hive beetle larva are the same size until the wax moth matures.
"Comparison of beetle and wax moth larvae
You can differentiate the hive beetle from wax moth
larvae by examining their legs. Both species have
three sets of legs just behind the head, but small hive
beetle larvae lack the series of paired prolegs that run
the length of the wax moth larva’s body." from

Figure 3 is a good large image of SHB larva

tecumseh:
not exactly correct. there are various form of wax moth (the lesser and greater being two prime examples) each produces a larvae of different size. diet will also effect the size enough that often time the greater wax moth can be mistaken for the lesser wax moth.

Size is relative to development. Not everything comes out full grown. There is a point where both, or all three, could be the same size.

I think you will find that a 3/8 in. long immature SHB larva is 1/2 the diameter of a 3/8 in. long immature wax moth larva. That, plus the difference in adult size, is why I say the wax moth larva is larger.

Whatever it is, there are no more. I just opened the hive and checked and everything looks good. The bees have closed off one hole to a one bee only size and have the other one closed down to about half.
I did find one SHB that met it's maker and that was all that I saw.
The bees are covering the comb where the larvae were found on the bottom board, but I saw nothing out of the ordinary.
I will keep checking when weather permits.
Thanks, Robert

you want bees that will take care of these problems themselves. if??? a hive has sufficient population when you do have serious wax worm or shb problems you will see debris being tossed out the front door. the wax worm works real fast and the shb a bit slower to totally overtake a hive.

Please take a look at the pictures in the links I posted. American Bee Journal, August 2011, page 770, also has the comparison image filling the frame. The difference in diameter is minimal (and can be nonexistent based on nutrition)between wax moth and small hive beetle larva of the same length.

I'm wondering if they did not take care of these themselves. I found them on the bottom board under a screen on this TBH. It is possible that the bees threw them down there??
As I said in the first post, all of them were dead except for the one in the second picture and it was crawling when I found it.
I thought the SHB laid the eggs in the comb. If that is the case, the bees may have removed them and dropped them down there??
All of the wax moth larve that I have seen, were laid in the frames of the hive body of a lang hive. They were in a type of cocoon.
I looked at the hive today and saw nothing out of the ordinary, so maybe the bees are taking care of it.

tecumseh:
technically I think you are speaking of the pupae stage of the wax moth. it is the larvae stage where they do the most damage.

tecumseh:
maybe yes and maybe no. sometime under any screen debris could accumulate and the wax moth larvae could have developed in the location below the screen.
