    Default A New Way to Kill SHB

    I lost a large cutout to SHB . Again.
    I pulled a couple of frames this AM and the **** things were in the comb. I decided to try a new approach to getting rid of them and stuck the comb in a large plastic bag. I took a Propane torch and filled the bag with Propane gas and sealed the bag. About two hours later the beetles were still crawling around just as happy as they could be.
    Since Propane is a little hazardous to handle I thought, Why not try carbon monoxide? So I took the bag and started up the van. I pushed all the air out of the bag and stuck it over the tailpipe and filled it up, sealed it and thought "Die you suckers".
    It did not work the away I thought it would. BUT IT DID WORK.
    Almost immediately the larva came out of the cavities of the comb and started crawling around and the beetles went bananas also. Where I thought there would be 30 or 40 beetle at the most, there were over a 100 and the larva were five times that. What a mess.
    Four hours later the beetles started to die. That is not a misprint , 4 hours in 100% carbon monoxide. At six hours the beetles were dead and the larva were starting to die. At eight + hours the last of the larva quit moving.
    WHAT I DON'T KNOW is the effect on uncapped brood. Capped brood and honey could be brushed off and then would be ready to return to the hive so the bees could clean them up.
    If you have beetles (and everybody does) a large, strong hive can control the beetles but if you only have one colony and it swarms of the queen gets old, the beetles will overrun the hive is a couple of days. So you could take every other frame out of a box, brush off all the bees and put it in a plastic bag (Hefty bags seal tighter than ziplock ones)and gas the whole frame overnight. The next day take out the remaining frames and replace the clean ones.
    The carbon monoxide dissipates as soon as you open the bag so nothing goes into the hive. There is no pesticide involved and the bees will clean up any debris that you don't knock off the comb.
    It's also cheap. It just takes time for the sucker to die. They are very hard to kill.
    If someone tries it, please post the results.
    regards

    An interesting idea but unfortunatley the exhaust fumes from a vehicle are not 100% carbon monoxide although it is a component. According to wikipedia the exhaust ranges from Nitorous Oxide, Ozone, Carbon Monoxide, Carbon Dioxide, Particulate Matter and various volatile organic compounds. Remembering my High School chemistry it woud be primarily the volatile organic compounds I would worry about these are from alcohols, to benzene, to many other toxic compounds. If you had a source of pure Carbon Monoxide it might be good to battle SHB but I wouldn't want the other stuff in my wax. Good luck with it.

    what about sealing em up with some dry ice? as it "melts" it would release all of the CO2 and that should kill em all and the CO2 wouldnt hurt the wax. Ohh CO2 = carbon dioxide

    Seems the co2 would do the job too. might take longer, but if they can't breath...

    I think some gas is a great idea as long as you don't kill yourself.
    I would think capped brood and uncapped brood would also be effected.
    They are capped but the caps are O2 permiable or the larva would die.

    Car exhaust seems like a bad idea but CO2 seems like it could work.
    Then bee keepers could be blamed for all the global warming.

    If you want an easy out-of-the-box idea, here is mine: Place each frame in an unused box (or the whole hive with no bottom) and put the box in the middle of ashphalt. I would put a couple of unused boxes below it also. This would allow two things to happen. 1: The emerging bees would just be growing and they stay on the frame. The SHB have to drop to the ashphalt and since they need to make it into the ground instead of hot ashphalt..... They die.... In one month, all you SHB should be gone....

    Just thinking way out of the box..... Way out....

    Good luck, Phil

    Since SHB have now become a problem for me also, here is my plan: (note: All of my hives are on 2 -4x4", 12' long horizontal post held off the ground 18" by 6x6" post 3' in the ground) I have applied Round Up (at night) under and around all my hives (its doing a great job). I have saved bags from cattle mineral. These bags are a very sturdy plastic, fiber bag. I will be cutting them so they make a flat rectangle and placing them on the scorched earth below the hives. I will place creek rock and mineral salt (cattle mineral) on the bags. The SHB larva will drop on to them and since they can't make contact with the earth they crawl around and get stopped by the salt......

    Just my idea. I have no idea if this will work.
