You can do it, but it doesn't guarantee egg death, so you'll just end up having to re-treat for endless cycles. The only really surefire way I've found to get rid of those little buggers is to completely change the soil for fresh, and if it's a plastic pot, replace with a terracotta one.

They're often an ingredient in soil bought at big-box stores, which is why I'd normally reccomend sterilizing the soil and pot in the oven before doing any changes.
