Reading Time: 6 minutes

House renting comes with its fair share of responsibilities, and yes, that includes ensuring your houseplants are in tip-top shape. Ever wondered How To Kill Scale On Houseplants? If you haven’t, consider this: a whopping 70% of indoor plant deaths are due to pests and neglect. Keeping houseplants healthy not only adds a fresh touch to your living space but also contributes positively to your indoor air quality.

What Are Scale Insects?

Let’s dive right into scale insects are not your houseplant’s BFFs. These tiny freeloaders look like they’re just chilling on your plant, but they’re up to no good!

The scale insect has a flat, oval shape and a protective shield-like covering. Some species have a slight waxy or armored look to them. While they might sound like knights in shining armor, they’re really just plant pests in disguise.

Now, let’s play a game of ‘Life Cycle Trivia’! What has eggs, nymphs, and adults, but no larval stage? That’s right, it’s the scale insect! These bugs go from eggs to nymphs, eventually turning into adults. Unlike other pests that might come and go, scale insects are more like that pesky cousin that overstays their welcome. They prefer to settle in one place for their whole life.

The consequence of hosting this unwanted guest? Damage. They suck out plant juices and, if not controlled, can cause severe damage. The result? Weakened plants, poor growth, and sometimes even plant death.

Signs That Your Houseplant Has Scale

Who left this sticky mess? If you find a gooey substance called honeydew on or around your plant, it’s a tell-tale sign of scale. But wait, there’s more! This honeydew attracts another villain to the scene: sooty mold. This mold isn’t just an aesthetic issue; it can also block sunlight, affecting photosynthesis.

If you’re thinking scales are easy to spot because of their size, think again. These minuscule monsters are often overlooked because they blend in. If you see tiny bumps on the stems or leaves that seem out of place, congratulations (or not), you’ve found them.

You may also notice your plant’s leaves turning yellow and wilting, much like how we look after missing our morning coffee. Stunted growth in plants can also indicate a scale invasion.
