How I Get Rid of Scale on My Houseplants
A few days ago I noticed my houseplants had scales. This isn’t the first time, and I know it won’t be the last time I fight against these little insects.
Scales are pesky little creatures that can literally suck the life out of your houseplants. They are usually hiding beneath their hard outer shell. This shell is what makes them difficult to get rid of. They only crawl at a certain stage in their life cycle. Come to think of it I don’t think I’ve ever seen one crawl, nor have I ever seen a picture of one crawling. I’ve only read about them crawling after they hatch.
Here is a picture of the scale on my plant
The round little bumps are the scale.
These insects will kill your beautiful houseplants if you don’t take care of the problem. It’s also gross to think about insects all over your plants in the house. Cleaning your houseplants is a must if you want long living, beautiful, healthy plants.

Symptoms of Scale Infestation
Scales are sneaky and they usually go unnoticed until your plant is looking sad, yellowed, and droopy.
The first thing people usually notice is a sticky sap like substance called honeydew on the surrounding area of the plant. You may also notice the stickiness on the leaves below the leaf with the scale. This stuff can ruin drapery, couch fabric, carpet, and wood. It’s not easy to remove the honeydew if you leave it sitting too long before cleaning it up.
I use the mixture I kill the scale with to clean the floor around my plants too. I have acid stained cement floors in my living, and dining room, so I don’t have to worry about carpet being damaged. I also use the solution on my wood floors around my stairs to clean the sap off.
The best thing is to catch the scale before the honeydew gets onto any of your floors or furniture and ruins them.
Home Remedy For Getting Rid of Scale
PLEASE READ BEFORE USING
I have used this solution on my plants many times without any damage to my plants. However, I strongly suggest testing on a couple of leaves before using this on your entire plant. If you don’t test, don’t blame me if your plant dies. You have been officially warned LOL.
I also like to use rubber gloves so my skin does not absorb the alcohol or dry out my hands. If your plants are too big to take outside make sure to protect your floors and furniture. This stuff will drip off the plant.
Homemade Insecticidal Soap Recipe
1 quart water
1 tsp detergent (I used a generic brand, you can also use plain Dawn)
3 Tbsp Isopropyl Alcohol 70%
Mix all the ingredients in a spray bottle and you are ready to go.
I use a moistened microfiber cloth to wipe the plants.
Spray one section of the plant at a time saturating the entire leaf with the solution. Then carefully wipe each leaf to remove the scale and sticky residue. I go leaf by leaf. This can be a bit time consuming, but I found this works best for my plants. Make sure you get all the nooks and crannies.
Here is a picture of a couple of the plants I had to work on. The tall one I used to take outside, but now it’s too big so I work on it in the house.
It’s a good idea to check your plants weekly or at least monthly to see if new scales show up. In my case they seem to come back in full force every few months. I try to catch them before there are too many. I just had to do major surgery on one of my large plants because I waited too long. Now it sits outside with one remaining leaf. It may end up in the trash, time will tell.
I hope this post helped you
I’m not a plant expert, just someone who has loved houseplants since I was a kid.
Do you have problems with scale? I would love to hear how you get rid of them.
I love comments, so please feel free to leave one.
Cheers,






















I only have one plant in my house, sadly. My cats eat plants and get sick. Yours look beautiful, though! Pretty!
OH, that’s not good if the cat eats them.None of our animals ever ate any. Now we are animal free. At least for now. We do have a goldfish out in the pond if that counts lol.
Thanks for stopping by.
I have 2 or 3 houseplants left and those are slowly dying…. I had tons but they’re so much work! LOL! I used to forgot to water them all the time.
Hi Jackie,
Yes they can be a lot of work. You have to really enjoy caring for them. I used to over water mine. I think watering is the hardest part.

to kill scale, mealy bugs, spider mites etc you need to add oil to the mix. 20 ml canola oil with 5 ml liquid dish soap will kill anything. You can use mineral oil instead of the canola oil. The oil suffocated the insects and eggs, it has no chemical action and canola and mineral oil are light enough they won’t clog the pores of the leaf. You MUST mix the oil and soap before adding it to the water. It has to turn white. Once it is white indicating the oil has emulsified, it can be added to 1 L of slightly warm water. If you add the oil and soap to the water without premixing, the oil will seperate and float on top of the water. For a few houseplants, use a 2 L sprayer and spray the plat till it is soaked. Under the leaves, top of the soil, top of the leaves, down the stems where the leaves join. You can not over spray the plant. Do not spray plants in hot sun, wait till evening and rinse the plant off before the heat returns the next day. In about 12 hours insects will be dead and can be washed off with a strong spray from the nozzle. If you can’t take your plants outside, spray them in the shower. Repeat about 2 weeks later.
Thank you Conrad,
I will try adding the oil to the mix for the plants I can take outside. My larger plants have to stay in place which makes it a bit more difficult.
I appreciate your detailed advice very much. I would love to kill all those pesky bugs for good. Scales love my indoor plants and it’s a constant battle.

I read through your helpful hints, but unfortunately how to get rid of the sticky stuff from carpet was not covered – can you guide me in the right direction……..Nina
Hi Nina,
I don’t really have any helpful tips about getting sticky stuff from carpets. I don’t have any carpets so it’s not a problem. I would check out some carpet cleaning sites and see if they can offer you some advice.
