If you’re growing succulents indoors (and possibly if you’re growing succulents outdoors), you are likely to encounter mealybugs at some point. If not, lucky you! Mealybugs are like a plague. They spread quickly from plant to plant and it can be difficult to get rid of them. Fortunately, I’ve discovered a simple way to kill them that also keeps your succulents safe from burning or other problems normal pesticides may cause.

What are mealybugs?

Mealybugs are nasty little bugs that like to eat new growth on succulents. It’s difficult to say exactly what causes them to show up, but overwatering is a common cause, as well as over fertilizing. They tend to show up on indoor plants the most as the temperatures are more temperate, but they can show up on succulents outdoors too! These little guys usually hang out in a white web-like substance in the nooks and crannies of your succulent. Their favorite place to hide is right where the leaves meet up with the stem. This makes them hard to see and hard to kill.

If they aren’t treated quickly, mealybugs will spread all over a succulent and to nearby succulents as well. It’s impressive how quickly they move, and frustrating too. As they move, they eat away at the succulent. Often, this will stunt the growth of the plant and cause the new growth to look mis-shaped or smaller than usual. They may also leave some dents in the leaves if they are left for too long.

How can I get rid of mealybugs?

While many plant pesticides will kill mealybugs, the best solution I’ve found to kill them is 70% isopropyl alcohol. Many people recommend using q-tips to dab on the alcohol, but I’ve found that a spray bottle is much more effective and easier to use. I actually keep a little travel sized spray bottle next to my plants so I can kill the nasty things as soon as they show up. I do use a larger one if the infestation gets out of hand or affects very many plants.

When you first notice the mealybugs, move your infected plants away from everything else. Mealybugs spread quickly and you don’t want to risk other plants getting infected. To kill the mealybugs with the alcohol, simply spray the alcohol directly on the mealybugs, wherever they are on the succulent. Be sure to check those hard to see places near the stem. Spray them really well with the alcohol. You’ll notice the web-like substance will almost disappear as soon as you spray them and a little brownish/black bug, the size of a crumb will be left.

Generally, if you catch the mealybugs early just one round of alcohol spray will be enough to kill them. If you didn’t quite get them all though, they may come back in a day or two. Continue to spray them until they don’t come back.

If you’ve had a large infestation, it may be a good idea to pour alcohol over the soil the next time you water. This will kill any bugs or eggs that are hiding out in the soil.

Doesn’t the alcohol damage the succulent?

Nope! The great thing about alcohol, as opposed to other pesticides, is it’s completely safe for succulents. I’ve had a few plants with a really bad mealy bug problem that I have pretty much soaked with alcohol a few days in a row. They didn’t show any signs of burn or damage from the alcohol. The alcohol itself evaporates quickly, so it’s just water that remains. If you use the spray bottle, it won’t get too much on the leaves so it evaporates before any damage may occur.

Are there other ways to kill mealybugs?

Yep! I’ve had people suggest adding a little bit of dish soap to water and spraying or dabbing that on. You can also use systemic pesticides for house plants. Lady bugs also keep mealybugs away! The best solution, and cheapest, I’ve found though, is the rubbing alcohol. It is the only one I’m confident will eliminate the mealybug problem and won’t damage your succulents.

My friend Jacki at Drought Smart Plants has put together an ebook about plant pests and how to treat them. If you’re looking for more information about bugs that may be infecting your succulents, I’d highly recommend checking it out!

  1. I’ve been using alcohol in a spray bottle when I find mealy and scales but I was afraid to use it as a drench on my soil. I have taken plants ive gotten at the nursery with root mealys, sprayed the roots, then washed all the soil off and replaced it with new clean media. I did however get excited over a bunch of 1″ echeverias I got from an upscale nursery thinking they took special precAtuions to not sell bugs (I won’t ever make that assumption again) I planted a bunch of plants into pots without checking them properly. On the last plant I was saving for another project, I popped it out of the pot it came in, and to my horror it was invested!! so out came my spray bottle of alcohol. I’m afraid to not rinse the plant off immediately though because the rubbing alcohol I find around where I live is all 90 percent and I’m afraid of doing damage. I’m also afraid if I water it down I will water it down too much and it won’t be effective. I did a really watered down drench on my new project, but I am going on a search for 70 percent alcohol to soak the suckers! I was able to eradicated a 15′ x 30′ greenhouse invested with mealys with constantly walking around with a spray bottle of running alcohol… I did throw away a few of the worst affected plants. But the alcohol did the trick and I don’t have to pull it out nearly as often anymore!

Wondering who I am?

Let me introduce myself... My name is Cassidy Tuttle and I’m a professional photographer turned succulent addict. These are my two sweet children and wonderful husband in the photo with me!

My adventure with succulents started with three small plants on the window sill of my basement apartment. Within a year I had propagated them and purchased more, totaling over 100 plants!

It’s been a fun adventure since then as I’ve drowned, burned, frozen, and starved my collection of succulents. This site is where I teach you how to avoid all those mistakes I made or help you recover from them.

While I’ve killed plenty of succulents in the last few years, I’ve also kept hundreds alive and thriving, and I know you can do the same!

Did I mention I wrote the book on succulents?

It’s true! I’m the author of Idiot’s Guides: Succulents which is designed to help those of us who love succulents (but are limited to growing on our window sills and porches) keep our succulents looking great.

You can purchase my book through my Amazon affiliate link here or pick it up at your local Barnes and Noble.

If printed books aren’t your thing, I’ve also written several ebooks about succulents on various topics including indoor growing, watering and propagating. You can check those out on this page.

My goal is to help you not just keep your succulents alive, but help them thrive no matter where you live.

Whew! That’s a lot of stuff!

I’m impressed you’ve made it this far down. You should probably be rewarded for that…
