I have a problem with fungus gnats. So I buy some mosquito dunks and throw
one in the watering can and let sit over night. Water completely the next
day. Start this about 2 weeks before you bring yjr plants indoors. It takes
awhile to kill the gnats. or you can spend big bucks for "Gnatroll" which
does the same thing.

How do you treat your houseplants that have been outdoors all summer?
