Sometimes you would want to sterilize terrarium / isopodarium equipment (like cork bark pieces, or other tree bark, or other items) for various reasons. Perhaps you see too many mites, fruit-flies, or for other reasons. There are four methods that can help you towards that direction and effectively sterilize those items for you.
Boiling Water Method
- Preparation: Bring a pot of water to a rolling boil.
- Submersion: Carefully submerge the terrarium items in the boiling water for about 5-10 minutes. This heat will eliminate insects and their eggs.
- Cooling: After boiling, remove the items and allow them to cool completely on a clean surface.
- Drying: Place the items in a well-ventilated area to air dry completely.
Hydrogen Peroxide Method
- Mix Solution: Prepare a solution of 3% hydrogen peroxide and water in a spray bottle (50/50 mix).
- Application: Evenly spray the terrarium items, ensuring thorough coverage.
- Contact Time: Let the items sit for 10-15 minutes.
- Rinsing: Rinse the items under running water to remove any residual hydrogen peroxide and mild insects.
- Drying: Allow the items to dry in a well-ventilated area.
Vinegar Solution Method
- Mix Solution: Combine equal parts of white vinegar and water in a spray bottle.
- Application: Spray the items generously and ensure they are well saturated.
- Contact Time: Let the items sit for 30 minutes to effectively kill any insects.
- Rinsing: Rinse thoroughly under running water and allow the items to dry completely before use.
Freezing Method
If you have space in your freezer, and the items can fit there, that is another option. But, as a previous owner of house plants, and battling thrips (the black species that it’s impossible to eradicate) I have to let you know that – at least thrips – can hibernate for 1 – 2 weeks ( and possibly months?) and simply reappear again at room temperature. I don’t know if that is the case with other insects as well, but I assume it could be. So, I would only recommend this method as a last resort.
Important Considerations
⬥ Avoid High Temperatures: Do not use an oven or high-heat methods, as these can damage the structure of the items.
⬥ Check for Damage: Inspect the items before and after the process to ensure their integrity is maintained.
