If it's not to tender of a
plant, take it outside and spray the aphids off with a hard stream of water from the garden hose. I use Safer's Soap too. The Buglady's right though, you need to be sure it won't harm your
plant. It will list some
plants on the label that you shouldn't spray. If you decide you can use it, follow up with a second spray about 3 days later cause you won't get them all the first time. Then check again in a week or so. You should see a big improvement but there might still be a few survivors.
