I have an indoor Ficus tree and the soil in the container has developed Symphylans. I dumped the soil out and replaced it but I noticed the little critters are still there. Is there anything I can use to kill them without harming my Ficus tree? Thank you.

I would try treating the soil with neem oil. This should kill them and is still safe for your plants, people in the house and pets.
