Hi, Cassandra...a safe bet would be to use an insecticide soap...or a simple rose spray. There are a few that are available at any garden center type place that have been formulated to use on thrips and others that are actually very gentle and can be used to treat plants in bud and even flower. They are already diluted and all you really have to do is follow the directions and they will work pretty well for you...don't want to take any chances with your first one! Hope you enjoy it!
