The most common pest to infect a succulent are mealy bugs. Thankfully, getting rid of them is not difficult. If these insects are infesting your indoor succulents, all you need is isopropyl alcohol. You can dab alcohol onto the affected area with a Q-tip, or you can spray it onto the leaves directly. Be sure to select 70% isopropyl alcohol for this job. And don’t worry; this concentration of alcohol is entirely safe to spray onto succulents.
