Identify the greenhouse millipede
Physical appearance
The greenhouse millipede, scientifically known as Oxidus gracilis, is a small creature that measures around 1 to 1.5 centimeters in length. It has a cylindrical body with numerous segments, each one bearing two pairs of legs. The millipede’s exoskeleton is typically dark brown to black in color, and it may have a glossy appearance. Some individuals may also have small spots or patches of red or orange on their body.
Habitat and behavior
Greenhouse millipedes primarily inhabit warm and humid environments, such as greenhouses, gardens, and compost piles. They thrive in moist conditions and are often found in areas with abundant organic debris. These millipedes are nocturnal creatures and tend to hide during the day, emerging at night to feed on decaying plant matter and organic material. They are not harmful to humans or pets, but their presence in large numbers can become a nuisance.
Preventive measures
Maintain cleanliness and hygiene
The first step in preventing a greenhouse millipede infestation is to maintain cleanliness and hygiene in and around your greenhouse or garden. Regularly remove any plant debris, fallen leaves, and dead vegetation that could serve as a food source for millipedes. Keep your greenhouse tidy and free from clutter to reduce potential hiding spots.
Reduce moisture levels
Greenhouse millipedes thrive in moist environments, so it’s crucial to eliminate excess moisture. Ensure proper drainage in your greenhouse by fixing any leaks or water accumulation issues. Avoid overwatering your plants, as this can create a favorable environment for millipedes. Consider using a dehumidifier if the humidity levels remain consistently high.
Manage organic debris
Since greenhouse millipedes primarily feed on decaying plant matter and organic debris, proper management of these materials can significantly reduce their population. Regularly clear away fallen leaves, dead plants, and excess mulch. Avoid overusing organic fertilizers, as they can attract millipedes. Maintaining a proper balance of organic material in your greenhouse can help deter these pests.
Control temperature and humidity
Monitoring and controlling the temperature and humidity levels in your greenhouse can discourage the presence of millipedes. Avoid creating excessively warm and humid conditions that are conducive to their survival. Use proper ventilation techniques to promote airflow and reduce moisture buildup. Additionally, consider using fans or heaters to regulate the temperature according to your plants’ needs.
Natural control methods
Beneficial insects
Introducing beneficial insects into your greenhouse can be an effective natural control method against greenhouse millipedes. Many predatory insects, such as centipedes, ground beetles, and rove beetles, feed on millipedes and can help keep their population in check. Consider releasing these natural predators into your greenhouse to create a balanced ecosystem.
Nematodes
Another natural control option is the use of nematodes, specifically Steinernema feltiae. These microscopic roundworms are parasitic to millipedes and can infect and kill them. You can apply nematodes to the soil in your greenhouse to target millipede populations. Follow the instructions provided with the nematode product for proper application and timing.
Diatomaceous earth
Diatomaceous earth is a natural pesticide that can be used to control greenhouse millipedes. It is made from the fossilized remains of marine organisms and contains sharp microscopic particles that can pierce the millipedes’ exoskeleton, causing them to dehydrate and die. Apply a thin layer of diatomaceous earth around the perimeter of your greenhouse or on susceptible areas where millipedes are likely to pass.
Predatory mites
Certain species of predatory mites, such as Stratiolaelaps scimitus, feed on small pests like millipedes. These mites can be released in your greenhouse to target millipede populations. Ensure that the environmental conditions, such as humidity and temperature, are suitable for the mites’ survival and reproduction. Follow the instructions provided by the supplier carefully for optimal results.
Chemical control options
Insecticidal sprays
If natural control methods are ineffective or you’re dealing with a severe infestation, insecticidal sprays can be used as a chemical control option. Look for insecticides specifically labeled for millipede control and follow the instructions for proper application. Be cautious when using insecticides, ensuring the safety of yourself, pets, and beneficial insects. It is essential to follow all labels and guidelines to minimize negative environmental impacts.
Dusts and granules
Dusts or granular insecticides can also be applied around the perimeter of your greenhouse or in areas where millipedes are active. These products typically contain ingredients that are toxic to millipedes upon contact. Always read and follow the product label, paying attention to any precautions or restrictions. Avoid applying these insecticides to surfaces that come into direct contact with plants.
Baits and traps
Baits and traps can be effective in attracting and eliminating greenhouse millipedes. You can create homemade traps using moistened newspaper or cardboard, which the millipedes will crawl into. Check the traps each morning and dispose of any captured millipedes. Alternatively, commercially available millipede baits can be placed strategically to attract and poison the pests. Follow the instructions provided with the bait product for optimal results.
Organic remedies
Garlic-based repellents
Garlic-based repellents can be used to deter greenhouse millipedes. The strong smell of garlic is believed to repel these pests. You can create a homemade garlic spray by blending garlic cloves with water and straining the mixture into a spray bottle. Apply the spray around the perimeter of your greenhouse or on areas prone to millipede activity. Reapply the spray after rainfall or as needed.
Neem oil
Neem oil, derived from the neem tree, is a natural pesticide that has insecticidal properties. It can be used to control various pests, including greenhouse millipedes. Dilute neem oil according to the instructions on the product label and spray it on affected areas. Neem oil works by disrupting the millipedes’ hormonal balance, eventually leading to their demise. Repeat the application as necessary.
Essential oils
Certain essential oils, such as tea tree oil and peppermint oil, have repellent properties that can help deter greenhouse millipedes. Dilute the essential oil of your choice with water and spray it around the infested areas. These oils can interfere with the millipedes’ senses and make the environment less hospitable for them. Ensure proper ventilation in your greenhouse when using essential oils.
Soap solutions
Soap solutions are a simple and effective organic remedy for combating greenhouse millipedes. Mix a few drops of liquid dish soap with water in a spray bottle and apply it directly to millipedes. The soapy solution disrupts their protective coating, leading to their dehydration and eventual death. Repeat the application as necessary, focusing on targeted areas with millipede activity.
Manual removal
Handpicking
If you have a small number of greenhouse millipedes, you can manually remove them by handpicking. Wear disposable gloves and carefully collect the millipedes from the affected areas. Place them in a sealed plastic bag and dispose of them properly. Regularly inspect your greenhouse for millipedes, as they can reproduce rapidly if left unchecked.
Vacuuming
For larger infestations, using a vacuum cleaner with a hose attachment can be an effective method of physically removing millipedes. Use the vacuum to suck up the millipedes from the surfaces and crevices of your greenhouse. Empty the vacuum bag or canister into a sealed plastic bag and dispose of it in an outdoor trash bin. Regularly clean the vacuum to prevent any lingering millipedes from escaping.
Cultural practices
Crop rotation
Practicing crop rotation in your greenhouse can help disrupt the millipedes’ life cycle and reduce their population. Avoid planting the same type of plants in the same area consecutively. Instead, alternate between different plant families. Crop rotation can help prevent millipedes from continuously finding a suitable food source and breeding grounds.
Plant resistant varieties
Choosing plant varieties that are resistant to millipedes can be an effective cultural practice for managing these pests. Research and select plants known to be less attractive or more resilient to millipede feeding damage. Consult gardening catalogs or local horticulture resources to identify millipede-resistant varieties suitable for your greenhouse conditions.
Sanitation
Maintaining good sanitation practices in your greenhouse is vital for millipede control. Routinely remove plant debris, fallen leaves, and dead vegetation. Clear away any excess mulch or organic matter that can provide hiding places for millipedes. Regularly clean your tools and equipment to avoid transporting millipedes from one area to another inadvertently.
Biological controls
Entomopathogenic fungi
Entomopathogenic fungi, such as Metarhizium anisopliae, can act as natural biological controls for greenhouse millipedes. These fungi infect and kill the millipedes by penetrating their exoskeletons and releasing spores that grow inside their bodies. Apply fungal products to the soil in your greenhouse according to the instructions provided by the manufacturer.
Nematodes
In addition to their use as a preventive measure, certain species of nematodes can be used as biological controls for greenhouse millipedes. These nematodes infect millipedes and provide an environmentally friendly method of controlling their populations. Apply nematodes to the soil according to the instructions provided, ensuring that the environmental conditions favor their survival and effectiveness.
Microbial insecticides
Microbial insecticides, such as Bacillus thuringiensis (Bt), are bacteria-based products that can target greenhouse millipedes. These insecticides release toxins that specifically affect the millipedes’ digestive systems, leading to their death. Follow the manufacturer’s instructions for proper application and timing when using microbial insecticides.
Physical barriers
Screening
Using screening or mesh materials can serve as a physical barrier to prevent millipedes from entering your greenhouse. Cover windows, vents, and other openings with fine mesh or screens to block the millipedes’ access. Ensure that the screening is properly installed and secure to prevent any gaps or openings.
Mulching
Mulching can provide several benefits in your greenhouse, such as moisture retention and weed suppression. However, it can also create a favorable environment for millipedes. To prevent millipede infestations, create a barrier between the mulch and the base of plants using materials such as gravel or plastic sheeting. This can discourage millipedes from crawling onto the plant stems and leaves.
