How To Get Rid Of Centipedes In Houseplants

Yes, there are occasions when centipedes live in the soil of houseplants. Palica, from Wikiedia Commons

I’m in need of your assistance. Caterpillars are everywhere in the soil of my majesty’s palm. Could you please tell me how to get rid of these and where they come from?

In the picture you sent, a centipede was visible instead of any caterpillars. And since centipedes tend to live alone, there probably weren’t many of them.

Centipedes eat soil-dwelling insects and other small animals rather than harming plants. In fact, they can defend your plant against its true adversaries, so you might want to think about leaving them alone.

Difference Between a Centipede and a Millipede?

Despite being distant relatives, gardeners frequently mix up centipedes with millipedes. They are an alternative species of arthropod, not an insect. They belong to a class of organisms known as myriapods, which is Greek for “with many legs.”

Typically carnivorous, centipedes have one set of long, spreading legs for each segment as well as lengthy antennae. Since they move quickly, it takes quite an exploit to catch one.

On the other side, millipedes are scavengers that consume detritus such as fungi, rotting leaves and roots, etc. They therefore frequently benefit as well. Certain species, however, are a little vegetarian and may occasionally munch on some plant roots. Typically, millipedes have two legs per segment, and those legs are positioned beneath their bodies rather than next to them. They have tiny antennae. When disturbed, they move slowly and rarely attempt to flee; instead, when frightened, they frequently curl up. Both have thousands of different species.

Although the word “centipede” literally translates to “100 legs,” they never actually have that many legs; instead, the number of appendages they have varies depending on the species and stage of development. Rarely do the tiny species that inhabit our plants have more than 30 legs. You probably guessed that the word “millipede” refers to an animal with 1,000 legs, and while most millipedes do have many more legs than a centipede, they never have 1,000!

Both are nocturnal and avoid light, which explains their sporadic appearance in plant pots, which are a suitable spot to hide from the sun.

How Do Centipedes Find Their Way into a Pot?

Centipedes probably moved into the pot outside if your majesty palm (Ravenea rivularis), which is typically the case as it is mostly sold as a patio plant, spent the summer outdoors. Centipedes enjoy cool, dark locations like a plant pot. When you brought your palm back inside for the winter, you took them inside from there.

Or perhaps when you purchased the plant, they were already there in the root ball (majesty palms are grown outdoors in the tropics, then shipped north in the summer, so could easily harbor a few creepy-crawlies). Then, when the palm was on your deck, they would have spent the entire summer inside the root ball.

It’s also possible that the centipedes went into the pot from within your home, though that’s the least likely scenario. Centipedes are known to live naturally in our homes, particularly in bathrooms and basements because they require a humid atmosphere to survive.

How to Bring Plants Indoors Without Centipedes

Centipedes and millipedes lurking in the root ball can also be removed using the same method as insects found in the soil of indoor plants that have spent the summer outdoors: soaking! Immerse the pot (and consequently the root ball) in a pail of soapy water. After 15 to 30 minutes of sitting completely submerged, remove it from the water and let it to drain.

To get rid of the centipedes in the pot in your hand, repeat the procedure indoors.

Centipedes (and millipedes) are not aquatic (at least, not the type that live in plant pots), thus they will drown during the soaking, which is one way this remedy works. That is, unless the soap kills them first since it suffocates them by obstructing their breathing pores.

Although you wouldn’t want to leave plants with their root ball submerged in water for days at a time because that would deprive the roots of oxygen and maybe cause rot, plant roots won’t be harmed during such a soaking.

As you can see, getting rid of centipedes from a potted plant is simple. However, it makes more sense to treat the plant while it’s still outdoors, before bringing it inside for the winter.

Plants will centipedes harm them?

Centipedes are more active than millipedes and feed on spiders and small insects, paralyzing their prey with venom. Their jaws, however, are too frail to do much harm to people besides a little swelling, as with a bee sting.

Like millipedes, centipedes prefer moist habitats, therefore getting rid of leaf litter or other things that absorb moisture will help reduce their population. Outdoor centipede treatment shouldn’t be a problem, but if it is, clearing away any material they might hide beneath will help keep them away.

Centipedes often do not harm your plants, whereas millipedes can. Since centipedes often consume insects that could harm your plants, they can actually be quite helpful in gardens.

If you spot a few centipedes and millipedes in your garden area, don’t be alarmed—they’re safer outside than inside. Only if you believe their population is out of control should you take action to control it. If not, take advantage of the fact that centipedes are yet another means of limiting the number of dangerous pests.

What pulls centipedes inside?

Even little mice may be eaten by some of the larger centipedes, such the enormous desert centipede. In contrast to their closely related millipede relatives, they do not eat leaf litter and other decaying vegetation.

Environmental Attractions

Centipedes prefer to live in areas that are chilly, dark, wet, near food supplies, and little disturbed. The majority of centipede species prefer the outdoors, although others, like house centipedes, may thrive both indoors and outdoors.

Centipedes in Homes

The majority of centipedes reside beneath logs, rocks, or other ground-based debris in moist places. If more friendly conditions for food or shelter are offered, they might manage to go inside. People are often repulsed by the pests but aren’t sure what attracts centipedes or how to keep them out.

What Attracts Centipedes to Homes?

Centipedes prey on species that invade dwellings, such cockroaches and spiders, therefore a surplus of prey frequently tempts these pests inside. Centipedes may be found by residents in floor drains, boxes, trash on the floor, and cement block walls.

A heated home’s warmth and security may encourage centipedes to breed there. This frequently occurs throughout the winter when the bugs can’t survive outside or when extremely dry weather forces them within.

Are Centipedes Harmful?

Although centipedes can bite, the majority of species that are frequently found inside homes typically do not even puncture human skin if they do. Some people view them as advantageous since homeowners frequently want to get rid of the prey that draws centipedes into homes. Others, however, are enough to be alarmed by the pest’s emergence.

Home entry points for house centipedes include:

What eradicates centipedes from indoor plants?

Centipedes can be kept out of your home by removing excess moisture from damp locations like basements, under sinks, and crawlspaces. Use a vacuum to capture any centipedes you notice slithering around your home. On their website, the Missouri Botanical Garden advises controlling centipedes indoors by spraying ready-to-use pesticides containing carbaryl along baseboards and in cracks and crevices. To manage centipedes, however, chemical insecticides should only be used as a last resort.

What plants keep centipedes away?

Rosemary is not only a lovely shrub, but it also works wonders at keeping centipedes away. To help keep these bothersome intruders out of your house, you can utilize this perfume in a variety of ways.

Any landscape can benefit from the addition of rosemary shrubs. This plant has a variety of uses besides only keeping bugs away. These include using it in cooking and infusing it into oil to create bath products, as well as crafts like building wreaths! For a lovely insect repellent, plant this plant in place of the more typical landscaping plants.

Use rosemary oil to deter centipedes from setting up residence in your home. You can introduce a rosemary smell to the parts of your house where centipedes are most prone to reside by diluting it or using cotton balls. This will assist in letting centipedes know that your home is not the right place for them!

Can vinegar deter centipedes?

All types of interior pests can be effectively treated with this powdered substance, which is formed from crushed insect exoskeletons. The house centipedes’ bodies are punctured by the powder’s microscopic sharp edges, which also dry up the fat and oils inside, killing them over time. Sprinkle liberally, especially in moist areas, in cracks, around door thresholds, and in corners. After a few days, you can vacuum it up. At least 24 hours should pass before vacuuming. Iterate as necessary.

Get rid of their food supply

This entails getting rid of the delectable insects that house centipedes enjoy munching on, such as roaches, silverfish, flies, and moths. Safe options for getting rid of these pests include sticky traps, vinegar, cedarwood spray, salt and/or baking soda put on thresholds and in corners, and the aforementioned diatomaceous earth.

Clean and/or seal external entry points

Things that help them hide are attractive to house centipedes. It may be possible to prevent them from entering your property by removing any debris that could become wet from the area surrounding the perimeter, like as leaves, dirt, grass clippings, or weeds.

Clean drains with vinegar or bleach

House centipedes are frequently discovered in the cabinets beneath the sink, close to the drains in the bathroom, or in the kitchen. Usually, you can keep them out of the drain by pouring vinegar or bleach down it. Add another half cup of vinegar after an hour has passed. Use a 50:50 solution of water and bleach.

Are plant roots eaten by centipedes?

Centipedes consume mites, insects, insect larvae, young snails, and slugs that live in the soil. (Their toxic claws paralyze little insect prey.)

As a pair, centipedes and millipedes work to break down organic materials and produce humus, which improves the soil.

Centipedes and millipedes can occasionally be a problem. Additionally, centipedes devour earthworms and living plant tissue. Sometimes millipedes eat plant roots, germination-prone seeds, and seedlings.

Although they are related to insects, centipedes and millipedes are not insects. Millipedes and centipedes both belong to the class Diplopoda, not the class Chlopoda, of arthropods.

Centipedes have 30 or more legs and resemble segmented 1-inch worms. They are brown, flattened, have a distinct head, and each segment has one set of jointed legs. Under garden trash, they spend the day hiding, and at night, they come out to forage.

A millipede can reach a length of 2 inches. Their bodies are segmented, cylindrical, and hard-shelled, and each segment has two short pairs of legs. Up to 400 legs can be seen in millipedes (not 1,000 as their name implies). They frequently spend the day coiled in the ground and are active at night.

When they consume the roots of asparagus, cucumber, lettuce, radish, and tomato, centipedes can become a nuisance. When they consume the roots of beans, cabbage, carrots, corn, potatoes, strawberries, tomatoes, and turnips, millipedes can be a nuisance.

Adult centipedes and millipedes spend the winter in the earth. They produce translucent egg clusters in the spring. Nymphs are little forms of adults. Centipedes reproduce in large numbers every year. There is only one millipede generation every year.

Sprinkle wood ashes, diatomaceous earth, or cinders around plants, seedlings, and next to rows of germination seeds to deter centipedes and millipedes from devouring the above-ground parts of plants.
