How to clear bugs off bonsai before bringing them inside for the season?
Had bonsai for 8 years never had a bug problem more than some aphids and a slug. This season there's been all sorts of bugs on my bonsai, mainly hiding underneath the pots. Thousand leg worms, rolly pollies, ear wigs, slugs, spiders, and baby spiders. Today I moved three pots and found all those underneath.
How can I ensure these aren't in the soil before bringing them in for the winter in a few months?
