18. Sampling colony adults sugar shake Alcohol wash (window washer fluid) Keep below 2-5% -- 5mites/100 bees

19. ManagementsManagements

20. Feeding, Moisture Control and Ventilation Moisture will kill bees …NOT cold! Locate hive out of the wind, in sun, protected. Use screened bottom boards, top ventilation. Feed bees to insure enough food stores Use screen tops with moisture collector. Burlap Straw Old Towels Etc.

21. ControlControl

24. Do you like/use Screen Bottom Boards? 95% of BIP survey respondents say THEY DO USE THEM

25. BUT SCREEN BOTTOM BOARDS apparently DO NOT REDUCE LOSSES Nationally no advantage (4 consecutive survey years: 2010-11, 2011-12, 2012-13, and 2013-14). However in northern states a 12.4% reduction of loss was recorded in last survey year (2013-2014).

26. Drone brood removal

27. Drone Brood removal 11% fewer overwintering colony losses detected in one of four survey years (2012-13). However in northern states a 10 % - 33% reduction in loss was recorded in operations that used this technique in 3 of 4 survey years (2011-12, 2012-13, 2013 -14)

28. yes

31. Do you use essential oils? Apiguard ApiLife Var

32. If you do use an essential oil -- APIGUARD - 26-31% fewer overwintering colony losses with use (4 consecutive survey years: 2010-11, 2011-12, 2012-13, 2013-14) APILIFE VAR 24.5-40% fewer overwintering colony losses with use (4 consecutive survey years: 2010-2011, 2011-12, 2012-13 and 2013-14) Essential oils in HONEY BEE HEALTHY & other supplements are not adequately control mites

33. Alternative material used Honey-B-Healthy

34. Do Acids control mites? Formic (MAQS) Hop Beta OXALIC

35. Acids for varroa control Formic ACID (MAQS) - 16-31% fewer overwintering colony losses with use (4 consecutive survey years 2010-2011: 2011-12; 2012-13; 2013-14) OXALIC ACID - 37- 41% fewer overwintering colony losses with use (2 consecutive survey years 2012-13, 2013-14) HOPGUARD II - 10% fewer overwintering colony losses with use in one survey year (2013-14) Smart chemicals need some smarts to use

36. Do you use/have you used a miticide? Smart chemical for Dumb beekeeper APIVAR (Amitraz) - 35-47% fewer overwintering colony losses with use (3 consecutive survey years; 2011-2012, 2012-13 and 2013-14)
