This is my first year with varroa but I am going to try to avoid using Bayvarol. I realise that this may result in my losing hives due to inexperience but I must start from where I am. I have one apiary at present with varroa to my knowledge but the infestation appears to be very light. By using different treatments I am hoping that the claims made for IPM are borne out in practice. A friend of mine has used Ipereat last year and this year, and reported good mite kills. This is an Italian product and there is a supply on its way to me. A Fogger is on its way to me to use FGMO and by all accounts this is showing good results. In the last couple of days I had an e mail from a New Zealand beekeeper who also has a Fogger on its way to him and we will be comparing results. Perhaps others may wish to share their experiences with us using IPM. Ireland and New Zealand on opposite sides of the globe both have varroa only for a relatively short time. I have made a simple sugar sprayer from a plastic mineral water bottle to add another string to the IPM bow. And thanks to the BEE-L archives for the assistance with this and also to those kind beekeepers who wrote to me with more help. At this stage I could not have less experience in using IPM but I am going to do my best with it. I can only hope that I will gain experience in using these IPM treatments faster than the mites can exploit my initial lack of experience. I realise that the problem of reinfestation will stalk my initial efforts, until the mite is fairly evenly distributed and until feral colonies and those maintained by non compliant beekeepers are eliminated by the mite. But Danish, Dutch and German beekeepers seem to be handling varroa without chemicals. So why cannot I? Only time will tell. Sincerely Tom Barrett Dublin Ireland
