Re: Varroa Mites predator?
> they are normally the reason people have low varroa drop as they eat them .
The link cited does indeed say that earwigs eat varroa:
Most beehives have a slide-in base, mesh floor and varroa floor. If the hive does not have this system, a sheet of white paper can be covered all over with Vaseline or milking balm and pushed under the colony to serve as a sampling tray during the monitoring period. The mites that drop off then adhere to the sampling tray. It is important to note whether there are any ants or earwigs present, since these insects eat varroa mites and can falsify the mite count obtained.
Pardon me for being skeptical, but I went looking for confirmation from other sources, and found virtually no other sources that suggest that earwigs are varroa predators. Can anyone supply any other references?
Randy Oliver does mention ants carrying varroa away from a "sticky board":
Cover the sheet with a sticky substance, so any live mites can’t crawl away—petroleum jelly, Crisco®, or proprietary insect trap resin. Pam® and shelf paper are not sticky enough. You can tell that your stickum is strong enough if the mites stay stuck in rows where they dropped from between the frames (although ants may carry mites away!).
