If you do not mind bringing bugs in the house it is very simple. Pick it up and carry it in and boom. Done.
But, if you have some teeney tiny critters lurking in little dark places when they get warm the the nice house they will multiply and you may have a problem. I have brought in plants without any prior preparation and have had no problem at all. It depends on where you live and how much infestation you have in your yards. Houseplants usually are not the problem unless you put them in the ground. I think you are talking of trying to winter your annuals and I have very little luck doing that, even in the greenhouse. I have lost so many trying to do that I have given up and felt it was just as easy to buy new ones. Maybe we are not on the same page here. ????"?
