It’s springtime again, and with it comes flowers, nectar, and lots of honey… but mites also become an issue early on in the season. Once they reach a certain threshold, they can do irreplaceable damage to a bee hive; it’s important to keep their numbers down come spring, so that your bees can make it through next winter.
Mites are little red bugs that latch onto and feed on honeybees, and weaken their immune systems so that they die of other diseases. There is no way to keep mites away from your bees, although some bees have been bred for their “hygienic” behavior, taking turns picking them off each others backs. Regardless of the types of bees you have, its good practice to take some precautionary anti-mite measures:
1. Screened bottom boards: Even if your bees are hygienic, it won’t make any difference if the mites can reattach themselves to another bee after falling down to a normal wooden bottom board. By using a screen board, with an oil lined pan underneath, you can trap mites and have a rough idea of what kind of mite problem your facing.
2. Sprinkle some sugar on ‘em: Mites can’t hang on to bees when they are covered in powdered sugar. So you can take a sifter, some powdered sugar, and sprinkle it on the bees in the brood chambers (where mites are concentrated). Works great with the screened bottom boards.
3. Drone traps: Mites are apparently very attracted to the larger brood comb that is used to make drones, and lay their eggs inside them whenever they can. By setting up some empty drone comb (larger size cells) and letting the queen lay some drone eggs inside, you can then takeout the comb before the drones hatch (24 days after being laid) and freeze it, you will eliminate a large population of mites.
4. Formic acid: Taken from a defensive chemical naturally produced by some ants, this is made into patties you can place on the hives. Mites can’t handle the stuff, and it can be used as a last resort to handle really bad situations before the hive collapses. The bees don’t really like it that much either. This stuff only works in weather up to 85 degrees Fahrenheit, so its better suited to cooler climates.
5. Oxalic Acid: Mixing it with water and spraying it over your bees is very effective against mites (97% reduction claimed). But it’s also volitile (bad for bees) when used too much.
6. Lemon juice: 1 part fresh lemon juice to 1 part sugar syrup (water + sugar). This is a non-chemical solution to the spraying technique. It is thought that the sugar syrup causes the bees to behave hygienically, and the lemon juice acts as a buffer preventing the bees from just eating the syrup.
