How to get rid of mites on ants? - briefly
Apply a registered acaricide (e.g., propoxur) to the affected colony, following label dosage, and isolate the nest to block further spread. Keep humidity low and remove debris regularly to discourage mite reproduction.
How to get rid of mites on ants? - in detail
Mite infestations on ant colonies can be controlled through a combination of environmental management, chemical treatment, and biological control.
Reducing humidity and temperature within the nest limits mite reproduction. Maintain nest moisture below 60 % relative humidity and keep ambient temperature between 20 °C and 25 °C. Adequate ventilation, periodic removal of excess moisture, and avoidance of water‑logged substrates are essential.
Chemical options include acaricides formulated for arthropod pests. Apply a diluted solution of a pyrethroid‑based product (e.g., permethrin 0.5 %) directly to the nest surface, ensuring thorough coverage without harming the ants. Follow manufacturer dosage guidelines and observe a 24‑hour withdrawal period before any experimental observation.
Biological agents provide sustainable suppression. Introduce predatory mites such as Stratiolaelaps scimitus, which prey on pest mites without affecting the ant workers. Release a population density of approximately 10 predators per cm² of nest area and monitor predation rates weekly.
A practical protocol:
- Inspect the colony weekly for mite presence using a stereomicroscope.
- Adjust nest humidity and temperature as described.
- Apply acaricide spray once every 10 days, rotating with an alternative active ingredient to prevent resistance.
- Introduce predatory mites after the first chemical application, allowing a 48‑hour interval.
- Record colony health indicators (worker mortality, brood development) to evaluate treatment efficacy.
Regular sanitation of the surrounding environment, removal of debris, and isolation of infected colonies further reduce reinfestation risk. Combining these measures yields a comprehensive strategy for eliminating mite burdens from ant colonies.
