Varroa mites, also known as bee mites, pose a significant threat to bees, causing large-scale bee deaths. Therefore, effective control of varroa mites is essential. Let's explore the methods to eliminate varroa mites in bees.
Methods to Eliminate Varroa Mites
1. Using Varroa Mite Fumigation Agent
Use a fumigation agent specifically designed to kill varroa mites. Follow these steps:
-
Timing: Choose evening time when bees have returned to the hive.
-
Application: Use 3-4 fumigation agents per standard hive. Place a sheet of paper at the bottom of the hive and seal the hive entrance.
-
Duration: Fumigate for about 20 minutes, then open the hive entrance and remove the ash.
-
Disposal: Collect the mites that fall onto the paper and burn them the next morning.
-
Frequency: Depending on the severity of infestation, fumigate 3-4 times, with a 3-day interval between treatments.
2. Spraying Insecticide for Mite Control
Spray insecticide to control varroa mites. Here are the steps:
-
Timing: Choose a windless morning or evening.
-
Preparation: Use a micro sprayer to apply a 1:150 insecticide solution or a 25% insecticide solution diluted 3000 times with water.
-
Method: Alternate between the two solutions for better results.
3. Manual Isolation for Mite Control
Isolate the brood frames to control mites. Follow these steps:
-
Isolation: Isolate the brood frames within the hive and move them to a supers box, providing empty frames for the queen to lay eggs.
-
Replacement: Replace the queen excluder with a mite excluder.
-
Duration: After approximately 24 days of isolation, the mites in the supers box will die due to lack of food and breeding grounds.
-
Effectiveness: This method can achieve an efficiency rate of over 90%.
4. Using Mite Treatment Strips
Use treatment strips to control mites. Follow these steps:
-
Installation: Fix fumigation treatment strips like Varroa Pop with thumbtacks between the second bee lane in the hive.
-
Dosage: Adjust the dosage based on the strength of the bee colony: 2 strips for strong colonies and 1 strip for weak colonies.
-
Duration: Each treatment lasts for 3 weeks.
-
Effectiveness: The strips provide long-lasting mite control, effectively killing emerging mites, with up to 100% effectiveness.
5. Other Methods
There are two primary types of varroa mites: large varroa mites and small varroa mites. Use the following methods:
-
Water-Based Insecticide: Kills large varroa mites.
-
Sublimed Sulfur: Kills small varroa mites.
-
Alternation: Alternate between these methods to prevent resistance.
These are the methods for eliminating varroa mites in bees. Varroa mites are cunning and can use bees' bodies to evade beekeepers. Therefore, it is crucial to use high-efficiency, non-polluting, and residue-free varroa mite control agents.
