    It can take a while to get rid of them because their shells prevent the pesticide from penetrating. It must be applied every week for a month or more. This article explains:

    I looked up weather averages for your location and it doesn't appear that you have any freezing weather. In that case, the tops may die down but it should return in spring. It also reproduces from seed, so you should have seed starts as well. You shouldn't have to take in any starts. However, just in case you get a bad winter, you may want to move one of the pots into the garage over winter. Just water about once a month.

    Often, a plant doesn't bloom because it isn't getting enough light, or it is getting too much nitrogen. Hold back on the fertilizer and see if that helps.
