Re: Coconut Husks & Gnats
I’m not sure if this applies for gnats specifically but I’ve heard of freezing the substrate as a preventative for bugs that might be hanging out in substrate but I’d think you’d want to freeze it for more than 24 hours to be safe. I’m not sure if this genuinely works, but it doesn’t hurt to try.
Another way is to bake the substrate. This is probably a better option than to freeze. Just make sure you soak the substrate a while before you bake it. I’m not sure what the recommended temp and time to use is but hopefully someone will be able to answer that for you.
I don’t know much about gnats but I know they can reproduce really quickly, and can be really hard to get rid of, so just make sure you are doing proper and regular cleanings and hopefully they won’t be a problem for you.
Re: Coconut Husks & Gnats
I had a substrate/gnat problem, I put the substrate in a shoebox size tub and put it in the microwave for 3 minutes.
I put it in for a minute and half and the gnats were still moving around.
