I currently have six hives. They range from deep singles to double deeps with double mediums on top. Two hives have much more shb's than the others. My good hives i only see one or two. the bad effected hives, i kill at least ten per hive. Besides size, all the boxes are strong and full of bees. Why are some hives affected and the others aren't? Btw, they are in the same place and all are partially shaded.thanks
1.. The more shade, the more SHB.
2.. The more empty space in the hive, the more SHB.
3.. The more small areas for them to hide, the more SHB.
IMHO ten shb are not shb...... If I worried about ten shb I would be standing there all day with a hive tool :-D And where are the ten sequestered in the top when you open the hive? That is where you want them.
You don't see many in a strong hive, the weaker the hive the more problems you will see. If they have to much room in the hive shb's can get away easier also. I am like you, I don't want to see ten in a hive either. So far this year in going though my five hives I have only seen 2 or 3 shb's total. Mine are really strong colonies this year. Good luck

Nothing to find ten sequester in the top of the hive in these parts......corralled in the corners by the bees.
When I first got my bees, established hives, they were full of SHB's, they were also full of bees. I have managed to be the number of shb's down, and the bees seem to help keep them out. I also moved the hives to a new location last summer. But I had the shb's numbers down pretty good before moving them. I had 1 have last year that had 6 to 10 shb's the rest were 0 to 3. Maybe just lucky this year. It's nice to not see any or many.

I'm in Central Arkansas and have several hives.
Small hive beetles are just starting to be a problem here.
I've had 2 weaker hives that looked good on Sunday and Wednesday afternoon they were hundreds of small hive beetle larva that had completely destroyed on foundation.
I've got the bees in a new hive but this year they're hitting fast and hard.
I talked to several beekeepers to tell them to look out for the small hive beetles.
4 called back the next day and said some of their hives are all but dead now, infested with beetle larva.
I'm using Beetle Barns with pieces of Check Mite Strips.
They can be in particular devastating to a split or a hive that has thrown a late season swarm.
Capt,
The biggest problem is that your bees have not developed the genetics to control the SHBs. Just like when the wax moths were introduced to the US in the late 1800s. The best thing to do is to add SBB with oil trays and STB to your hives until your bees develop the right genetics. You will find with the STBs that if you lift the lids every day you can kill a lot of beetles that are trapped up there. Be sure to put 1/8 " slots in the sides above the window screen for them to smell the hive and to get in it. With as many hives as you have, if they all had them, you will devastate the local SHB population quick.
With the Screen Top Boards you can open one about an hour before dusk and stand there and kill about a hundred or more in an hour. They land almost non stop and you crush them with your finger.

All due respect.... seriously?? If were only that simple?
As has already been said your bees must not be accustom to dealing with SHBs. The best thing I have found is SBB with oil trays. Don't know how many hives you have or what kind of bottom board but the oil trays are worth the effort to make and install if the beetles are bad. I just use hydrated lime in most of mine now but if a hive gets to having a problem with the beetles I will put veggie oil in the tray and keep the colony crowded with bees.

You may not realize this the active ingredient of checkmite+ strips (Coumaphos) has been linked to killing sperm inside mated Queens which will show up as a shotgun pattern or a drone layer. I did hear this from Jeff Pettis of the USDA bee lab Beltsville Maryland about 3 years or so. I do hope this is not your experience.
BEE HAPPY Jim 134 :)

That has been my and a relatively close beeks experience. We were killing thousands of beetles in our hives with the oil trays and STB and then their numbers seriously declined. Last year we both stopped using oil in the traps with no problems.
After I brought the hives home from the farm this spring, I they swarmed my hives with more beetles than I have seen for a while. After 3 weeks with the oil back on, they are back to low levels again. I am leaving the trays empty (dry) now as I clean them.

Maybe I misunderstood. I interpreted devastate the local population as in your the area surrounding your hives not just your hives your yard. Sure killing in your hive however the method helps that hive. But plenty to replace them at least here. Maybe because of rotting peaches and melons in the area?
SC,
One of the great things about the SBB is that it not only kills the beetles but it is also killing their larvae when they are ready to pupate, they try to drop out of the hive to get into the ground and land in the oil. It stops the entire life cycle. The other in hive traps do not. We do not have a lot of fruit on the ground here. As their name suggests, their preferred breeding site is your hives. With every hive in an area drawing them in, and they do, and almost every SHB and their off spring ending up in the oil, it really devastates the population with a lot of hives.
When I started, within a months time, every oil tray would be solid black with dead SHBs (thousands of SHB). Right now I have several of the trays that have had oil in them for almost a month and the worst one might have a hundred beetles in it. As I clean them out they will go back in dry. Then I just check them every few days and kill the beetles and larvae in the tray and dump out the pollen and trash because the larvae can develop in it.
Last year we (the beeks in this area) did not use oil because their numbers were so low. Maybe that is why they were heavy when I brought them back into town this year.
Jim
I realize their preferred place we think. is the hive. So what do they do if they have no hives to support them. They do what every other creature does, they adapt. Don't let it fool you. they love rotten fruit. Especially in the melon family. Although I am sure they will choose the pollen and honey first :(
Is the shb's first choice melon patches or bee hives? Naturally, in hives used to pollinate melon fields the beetles will show up in the hives first...the melons have not ripened and no rotting ones are in the field yet.
But, I wonder if in the wild whether the shb first fed off of fruits or honey bee products from a bee tree. We call them "small hive beetles" probably because we are beekeepers and first encountered them in our bee hives. What about the melon growers? Did they first attack hives and then went to fruits as a secondary food source...or is it the opposite?
Seems I read that the first beetles arrived in North America via a freighter with a load of fruit...not with bees.
Ed
The first SHB were collected in Charleston Sc in 1996. And yes Charleston id a Port City. I imagine they came in on a ship and I doubt it had beehives on it, but I don't know. I could see bee hive coming in on the West Coast but never heard of it in Charleston.
I am sure the farmers pay them no mind as they feast on rotting fruit. On the other hand we nickname them Small Hive Beetle as they affect us totally different. They like a bee hive but I don't know if prefer is the right word. Basically I think shb are just opportunistic and the hive happens to be there. I can not see the range of the shb being as wide as it is if they don't feast on other sources. Just not enough beekeeping in my area to support an ongoing growing population. Of course most of this is just MHO :-D
I read somewhere that in harvested melon fields where the bad fruit is left to rot that there will be small clouds of beetles flying there.
The problem may be that the rotting fruit only lasts so long before it's gone, then the beetles seek other food. Beehives are year-long sources of food for the beetles so naturally they home in on the hives. :-x
It has been interesting this year, I'm almost scared to mention it...very low beetle counts. I'm wondering if the icestorm had something to do with lowering their numbers down here.... :? :)
Ed
I have no doubt that they reproduce in the rotting fruit.
One problem I see is that they cannot survive in most temperate climates with out hives to keep them warm in the winter. If the ground freezes, they do not survive. That is why we here in the south have the worst problem with them. I do not know of any other place other than the hive that they can survive freezing weather.
Jim
Ed,
Not many around here this year either. 2nd year beek and 2nd year oil traps.

The only thing I can attribute our low beetle numbers to is the cold and icey conditions we had this past winter. BUT...even with the layer of ice we had in the winter storm I'm sure the ground only froze an inch or so below that sheet of ice (if it froze at all). :? Maybe they weren't overwintering in the ground as deep as I was thinking they would. What would overwinter in the ground?....adult or pupa or...???
Ed
Winter time in Alabama you're going to make me laugh. :lau: :lau: :lau:
Seriously adult SHB can and do survive in hives in northern Vermont where
the frost go in the ground about the first 6 feet or so not bad where
I live in southwestern New Hampshire frost on it goes about 4 feet.
Thank you for putting a :) on my face ;)
BEE HAPPY Jim 134 :)

Hopefully we will figure how to freeze them out.... but it won't happen :(

Ed,
The SHB larvae go into the ground to pupate not the adults. From what I have read, they like wet moist soil not dry sandy soil. If we are lucky, they do not go very deep so that they freeze in the winter.
Jim
But Jim, would they pupate during the winter in the ground or would the adults simply stay clustered with the bees? You know, being as we live in a fairly mild climate (compared to folks like Jim134 ;) ) we may get the benefit of the beetles raising young year round and when the freezes hit maybe catch them off guard and freeze their little beetle butts off!!!! Maybe hitting a brood cycle for them....we can hope!!!! :evil:

As has been stated, 10 SHB in a strong hive is no reason for alarm. It's good that you are concerned however. SHB are always looking for an opportunity to overcome a colony. Colony strength and full sun are your best defences. I use bottom oil traps under my hives. They make me feel like I'm actually helping to combat this pest. When I first installed them I was shocked by the shear number of beetles they killed. Other members are able to keep bees without bottom trays just fine. They are time consuming to build and a hassle to maintain. I may migrate away from them as my colony numbers increase but I'll always keep them as an effective tool.

Ed the adults definitely stay in the hives during the winter, at least in my hives. :'(
Jim
Hmm, maybe three or four Beetle Jail Jrs baited with some cider vinegar and a little banana peeling mashed up and added it to it and these placed in the outer regions of the anticipated cluster area in late fall? Maybe lure the beetles into a good smelling and safe ;) hiding place?
