Mechanical Control of Pests
Mechanical controls are useful against pests; they don’t result in resistant pests. Here are some mechanical controls: Screened bottom boards reduce Varroa mite populations. Hive stands raised above the ground help to reduce Nosema and resist mammal pests. Providing adequate internal ventilation of hives reduces chalkbrood and Nosema. Use Small Hive Beetle traps. Use entrance reducers in cold weather to restrict mice. Also, use them any time you are feeding bees to prevent robbing and fighting at the hive entrance. Burn hive equipment and bees in the case of American foul brood. Terramycin only suppresses the vegetative, rod-producing stage of this bacterial disease. It masks the disease and does not kill the reproductive spores. Repeated use of Terramycin leads to resistant strains of AFB. Experienced trapper Bill Peterson is employing mechanical controls to remove an infestation of beavers flooding large areas of Peace Farm.
