Houseplants are the perfect way to bring a bit of the outdoors inside, offering beautiful foliage and purifying the air in your home. Unfortunately, they are sometimes plagued by pest infestations, and one of the most common culprits is scale. These tiny insects can cause serious damage to your plants if left untreated, so it’s important to understand what they are, how to identify them, and how to get rid of them.

What is scale on houseplants?

Scale insects are small, oval-shaped bugs that attach themselves to the leaves, stems, and branches of plants. They can be white, brown, or black, and they secrete a sticky substance called honeydew that can attract ants and other pests. Scale insects suck sap from the plant, which can cause yellowing, wilting, and stunted growth. If left untreated, a severe infestation can kill your plant.

Identifying scale on your houseplants

It can be difficult to spot scale insects, but here are a few signs to look out for:

– Yellowing leaves or stunted growth
– Sticky leaves or a sticky substance on nearby surfaces
– Little brown bumps on the leaves or stems (these are the scales)

If you suspect your houseplant has scale, it’s important to act quickly to prevent further damage.

Treating a scale infestation

The good news is that scale infestations can be treated. Here are some methods that you can use:

– Manual removal: If you only have a few scales, you can remove them with a cotton swab dipped in rubbing alcohol. Simply dab the scales to remove them.
– Pruning: If the infestation is severe, you may need to prune off the affected parts of your plant. Make sure you sterilize your pruning shears with rubbing alcohol before and after pruning.
– Insecticidal soap: You can use an insecticidal soap to control the scales. Make sure you follow the instructions on the label carefully.
– Neem oil: Neem oil is a natural insecticide that can be effective against scale. Mix it with water and spray it on your plant.
