Pests
Two things to watch out for:
Parasites that feed on bees
Bacteria and Viral Infections
Parasites
Varroa Mite
A Tick, oval shapes, 8 legs, visible to the naked eye, very tiny
Lives inside the bees body
Weakens the bee and transmits viruses which will weaken a colony and eventually kill it if left untreated
Grows rapidly through reproduction
Tracheal Mite
Can't see with then naked eye
Lives outside the bees body
Breeds on the inside of the bees
Enters the bee through the prothoracic spiracle
Bees infested with TrachealMites will crawl around in the grass, unable to fly because they cannot get enough oxygen
Treated with Menthol Pellets
Both are treatable
Deformed Wing Virus: The Wings don't develop and a bee that will never forage
Chemical Treatment
A pistan or checkmite strips used initially, but are no longer favored treatments
A piguard or Api Life Var (Thymol) or MAQs (formic acid) more widely and (more wisely) used
Recently legalized in the US, Oxalic acid, applied as dribble or vaporized
Other treatments include Apivar, HopGuard
Non Chemical Treatment
Drone Brood Removal
Green Plastic Frames with Large Cells
As soon as brood gets capped, you remove and place in your freezer
Can also get bees wax in the size of drone cells and cut to any size you want and place into your own frame
Can also uncap instead of freeze, this way you can inspect your pupa and you can see how bad the infestations are
Keep track and do it again and see it the % is decreasing, staying the same or decreasing to know how bad your infestation is.
Splits
Anytime you are not raising brood, mite population isn't increasing.
Take 1 hive and make 2 or 3 hives from that one hive by splitting them.
Which ever box doesn't have a Queen that is a chance for a Verroa not to reproduce and die.
This also cuts down your bee population as well
Queen Restricting
Restricting the queen to a smaller colony or restricting her all together
Cage the queen and go brood-less
Take the Queen and put her on an empty cell, put her under a frame, then remove and freeze that frame
You will loose honey production and you will loose colony growth
Genetics
Let the bees take care of it
They groom each other or do splits on their own
Hygienic behavior, they will clean out their own effected brood cells.
