1.Russian and European experiences reveal an infestation is usually fatal to colonies of European bees (Apis mellifera) within three to seven years.
2.Low levels of infestation are extremely difficult to detect.
3.It is a 7-10 year process to get chemicals registered, a process often costing millions of dollars.
4.Many of the 140 or so chemicals used worldwide for Varroa mite control are toxic to bees and beekeepers and their use risks contamination of honey and wax.
5.The Varroa mite develops resistance to chemicals in a short time. This is especially true when the chemicals are not used properly and/or dosage rates have not been adequately investigated.
