    they will overwinter in the hive as long as the hive is alive.

    That sucks. Do they lay eggs during the winter?

    Just because the bees slow down, doesn't mean the mites or the beetles do.

    The way it seems to work is that the longer your winter, the fewer shb survive. The shorter your summer....the less opportunity they have to reproduce. Shb are a tropical pest. The further south you go the more serious they become. Just ask those FL beekeepers.
    I don't think they're likely to become a big problem in IN.

    We've had SHB'S for three years in my part of Connecticut. And they survived the deep cold of last winter.

    We used to joke about hive beetles... Not any more.

    Where? In your beehive? In the cluster? They won't.

    Out in the open, say on a hive cover, who knows.

    the beetles and mites slow down too. They are more or less in dormancy/survival mode like the bees. The hive beetles will stay on the exterior of the cluster where the bees run them too. When the beetles get too cold die.

    One of the main problems is the beetles can hide in slotted top bars, they can overwinter very well here because they are protected from the bees running them out.

    Not knowing any better I bought frames with top and bottom grove. I have Lexan as part of my inner cover and when I took the out cover off one of the hives today I saw 3 or 4 SHB running for cover. They came off the top bar. I guess come spring we will see how things are.

    Oddly enough some Northern states have issues with them. It seems to be a combination of clay soil and long hard winters that keep them in check around here. Places with sandy soil seem to have much more issues. Places where winter isn't so hard have more issues.

    Last winter was my first one beekeeping. The hive died out over the winter and when I pulled everything out to clean it up there were still a few live SHB in the comb.
    I eat my peas with honey. Iíve done it all my life. It makes the peas taste funny. But it keeps them on the knife!

    They say they winter in the hive.

    I just don't know which hives they winter in. Not mine. I don't see even one until June or July.

    Suspect they either migrate or there are brought in.

    Our winters are up and down, one week it could be in teens, a week later 70s. This may be hard on the beetle population; The one's that don't get back in the cluster will die.

    Cold is a relative term. The colder it is, the longer it is the more beetles will die. Unfortunately they all don't die. So they are like mites in that they can get through winter with the bees.

    Yes. The ground could freeze as deep as 60" in Northern Minnesota, or as little as none in Southern Florida... Here it is 40"...

    I would not call it luck. Mid-summer I had plenty of them. Some hives were over run. It started as one or two per hive, by the end of the summer some hives had a hundred or more. Once Sept came and brought the 40 deg nights the numbers have dropped drastically. Down to a few per frame. There has not been a freeze yet, the closes we got was low 40s.

    Where did they all go? South?
    Think they migrate? I heard they can travel 25 miles to a hive.

    Certainly not as big of a problem as it is in southern climes, but SHB is definitely alive and well in Indiana. Last winter was the coldest in at least 40 years, and this summer many Indiana beeks reported seeing more SHB than ever before. This was the first year I've seen enough to warrent placing beetle traps in my colonies, and SHB was a frequent topic in our local club meetings.

    Food for thought.

    http://www.clemson.edu/extension/bee...ettle_ipm.html
    When beekeepers open their colonies, beetles often escape confinement and freely roam the colony again. If the colony is showing signs of stress, the bees may not be able to recorral the beetles, which may lead to an increase in beetle reproduction. Therefore, beekeepers should not open their colonies unless necessary, such times as honey removal from the colony or feeding to prevent starvation. This is particularly true during times of the year when beetle populations tend to increase which begins as early as May in the southern US and may continue till early fall. New beekeepers should resist the temptation to over manipulate their colonies. The queen simply does not have to be checked on a daily basis. Leaving colonies open during inspections can also lead to stress from robber bees from nearby colonies, especially during times of dearth.

    Here's the meat of the article:

    Doís

    maintain healthy, strong colonies to promote high beetocomb ratio

    monitor colonies for beetle infestation levels

    trap beetles using one or more of the trapping devices presently marketed

    physically kill or remove beetles when inspecting a colony, but do not leave equipment exposed for long periods of time which may lead to robbing

    remove weak colonies from an apiary when infested with beetle larvae and treat the soil

    extract honey from supers within 2 days of hive removal

    maintain good sanitary conditions inside and outside the honey house

    treat soil with Gard Star, if beetle larvae are present in the hive

    use Check Mite + in the hive as a last resort


    Donítís

    do not place colonies in shady, damp locations

    do not overmanipulate colonies when beetles are present

    do not leave colonies exposed during extended hive inspections

    do not oversuper colonies when beetles are present

    do not hesitate to move colonies to a new location away from an old apiary which has a history of beetle problems

    do not use pesticides that are not registered for SHB control

    When small hive beetles (Aetina tumida or SHBs) invade a beehive, they carry yeast which then grows on the pollen. As the yeast grows and ferments, compounds that are similar to the honey bee alarm phermones are released and strongly attract other SHBs.

    When the beetles become too many, the honey bees then abandon the hive, and this means that your family of nurtured bees are left without a home and you are left without honey.
