I don't bring semps or hardy sedum indoors for winter. Most of my plants are repotted in the spring when the go outdoors. Everything I've read said not to repot to bring indoors for winter as it causes to much shock and can weaken the plant making them more susceptible to an invasion of pests.
But if a person has been doing that all along and it has worked for them, by all means keep doing it.
Each person has a different micro-climate in their home, warmer/colder, dry/moist air and lots of sunny windows or not many at all. So it is a learning experience on what will work for you in your home. Just remember if the plant is happy and healthy it is less likely to be plagued by pests or disease.
You definitely want to carefully inspect plants and treat them for any pests before bringing them indoors.
Chewing or sucking type pests the systemic type drench or granules works. I will certainly be giving Lori's suggestion a try this year for the fungus gnats that spend part of their life cycle in the soil.
