How To Quickly Get Rid Of A Greenhouse Millipede Infestation

The best way to get rid of a greenhouse millipede is to manually remove them from the greenhouse. Just use a broom or dustpan to sweep them up into a bucket of soapy water, or vacuum them up and get rid of them outside. You DO NOT want to squish them because they release a really smelly odor, so just manually sweep them up and remove them.

Let’s get more into these little greenhouse millipede critters.

Understanding The Greenhouse Millipede

The Greenhouse Millipede is a cylindrical, segmented creature with two pairs of legs per body segment. It reproduces via eggs and undergoes several molts to reach adulthood. The millipede prefers dark, damp environments and is found in various regions across the globe.

What Is A Greenhouse Millipede?

Millipedes thrive in the damp darkness, recycling plant matter quietly and efficiently.

Their hard exoskeleton protects them from minor threats while their coiled posture when threatened serves as a defense mechanism against predators. Despite having numerous legs, greenhouse millipedes move at a leisurely pace, making it easy to spot them ambling along garden soil or underneath pots.

Their diet primarily consists of decaying leaves and other dead plant matter, playing an essential role in breaking down organic materials in natural ecosystems.

How Do They Grow And Reproduce?

The growth rate of greenhouse millipedes is influenced by factors like temperature and food availability. In warmer environments with plenty of organic matter to feed on, they can progress through their growth stages more quickly.

This rapid growth cycle plays a critical role in managing millipede infestations naturally since understanding it helps homeowners anticipate and disrupt their reproduction patterns effectively.

Preventing access to ideal breeding grounds by removing excess moisture and organic debris from around the home can significantly reduce their numbers over time.

Where Do Greenhouse Millipedes Thrive?

Greenhouse millipedes thrive in moist, protected environments where they can find plenty of organic matter to feed on. They prefer habitats that are dark and damp, such as under stones, logs, leaf litter, or mulch.

These conditions are not only ideal for their feeding habits but also provide a safe place for laying eggs and hiding from predators.

In gardens and greenhouses, these pests enjoy areas with high humidity and ample vegetation. Overwatered plant pots, dense ground covers, and compost heaps offer perfect spots for millipedes to settle down.

Managing moisture levels and clearing debris regularly can help discourage them from making themselves at home in these spaces.

Geographic Range

Continuing from the greenhouse millipede’s habitat preferences, it is important to note that these resilient creatures are found in a variety of habitats across North America, specifically in moist and decaying organic matter.

They thrive in environments such as gardens, compost piles, and greenhouses.

The greenhouse millipede can be found in diverse habitats, including gardens, compost piles, and greenhouses.

Pros And Cons Of Greenhouse Millipedes

Greenhouse millipedes can actually be pretty handy little creatures to have around. Here are some of their benefits:

The Pros

Pest Control:	They help keep your garden clean by munching on dead plants and fungi. This also means they can help control the spread of unwanted pests that feed on decomposing material.
Soil Health:	As they move through the soil and eat, millipedes help break down organic material, which improves soil health and fertility. This makes your garden soil better for growing plants.
Low Maintenance:	Millipedes are pretty low-key; they don’t require much from you. As long as there’s enough moisture and food (like dead leaves), they’re happy.
Non-Invasive:	Unlike some bugs that can be harmful to your plants, greenhouse millipedes generally don’t harm living plants. They stick to decomposing material, so your live plants are safe.
Educational:	If you’ve got kids, millipedes can be cool little critters for them to learn about the ecosystem and the role of decomposers in nature.

The Greenhouse Millipede has an overall length between .7”-.9” (1.8-2.3 cm) and width of .08”-.1” (2-2.5 mm). The typical lifespan of the Greenhouse Millipede is between 4-7 years.

As you can see above – they can be beneficial for maintaining a healthy garden as long as they are controlled.

But what are the cons?

The Cons

Overpopulation:	If they find your garden especially comfy, millipedes can multiply quickly. This might lead to them wandering into places you don’t want them, like inside your home.
Nuisance Factor:	Even though they’re harmless, having a bunch of millipedes crawling around can be a bit off-putting or annoying for some people.
Potential Plant Risk:	While they typically feed on dead plant material, if there’s a shortage, there’s a small chance they might nibble on young seedlings or soft roots.
Moisture Issues:	Millipedes thrive in moist environments. If your garden or greenhouse is too damp, it might not only attract millipedes but could also encourage mold and fungus growth.
Scare Factor:	Let’s face it, not everyone is a fan of creepy crawlies. Millipedes, with their many legs and segmented bodies, can be a bit unsettling for some folks or guests in your garden.
