Nematodes are microscopic worms that occur naturally in soil worldwide. Thousands of strains exist with different lifestyles. Beneficial nematodes attack only soil-dwelling insects and leave plants alone. Beneficial nematodes and the bacteria they spread are not known to be harmful to humans, animals, plants, earthworms, and other non-target organisms. They aggressively pursue insects like grubs, which can cause damage to gardens and lawns.
Key Facts
- Beneficial nematodes and the bacteria they spread are not known to be harmful to humans, animals, plants, earthworms, and other non-target organisms.
- Nematodes can be used for grub control in gardens without posing a threat to pets.
- Nematodes are safe for dogs and can be used for slug control in gardens. They are 100% biological and safe for dogs to dig and play on treated areas immediately.
Nematodes for Grub Control
One common use of nematodes is for grub control in gardens. Grubs are the larvae of beetles, such as Japanese beetles and European chafers, which can feed on the roots of plants and cause significant damage. Beneficial nematodes can be applied to the soil to target and kill these grubs. The nematodes enter the grubs through their body openings and release a bacterium that kills the grubs within 48 hours. Several generations of nematodes may live and breed within the dead pest, emerging to seek more grubs in the soil. Studies have shown that beneficial nematodes can be up to 96% effective against Japanese beetle grubs in field studies.
Nematodes for Slug Control
Nematodes can also be used for slug control in gardens. Slugs can spread a parasite called lungworm, which can be fatal to dogs if ingested. Traditional slug baits often contain chemicals that are toxic to pets, making them unsafe for use in areas where dogs may be present. Nematodes, on the other hand, are 100% biological and safe for dogs. They can be applied to the soil to target and kill slugs, reducing the risk of lungworm infection in dogs.
Application and Safety Precautions
When applying nematodes for grub or slug control, it is important to follow the instructions on the product label carefully. Nematodes are typically applied as a spray or drench to the affected area. The best time to apply nematodes depends on the weather and grub species, but it is generally recommended to apply them in the late summer or early fall when the grubs are actively feeding. Nematodes prefer a moist environment, so it is helpful to water the area before and after application. Keep the soil moist for at least two weeks to help the nematodes establish themselves.
Nematodes are safe for dogs and other pets, but it is generally recommended to keep pets off treated areas until the nematodes have had a chance to do their job. This will help prevent the nematodes from being accidentally ingested by pets.
Conclusion
Nematodes are a safe and effective biological control option for grubs and slugs in gardens. They are non-toxic to humans, animals, plants, and other beneficial organisms, making them an environmentally friendly choice for pest control. By using nematodes, gardeners can protect their plants from damage caused by these pests without posing a risk to their pets or the environment.

What precautions should be taken when using nematodes for pest control?
When applying nematodes for pest control, it is important to follow the instructions on the product label carefully. Nematodes are typically applied as a spray or drench to the affected area. Keep pets off treated areas until the nematodes have had a chance to do their job. This will help prevent the nematodes from being accidentally ingested by pets.
How long does it take for nematodes to work?
Nematodes typically take 2-4 weeks to effectively control pests. This depends on various factors such as the temperature, humidity, and the severity of the pest infestation.
Can nematodes be used indoors?
Nematodes can be used indoors in infested areas such as basements, garages, and pet areas. However, it is important to ensure that the indoor environment is moist and suitable for nematode survival.
How can I tell if nematodes are working?
You can tell if nematodes are working by looking for signs of dead pests. For example, if you are using nematodes for grub control, you may see dead grubs in the soil. You may also notice a reduction in the amount of damage caused by pests.
Are there any risks associated with using nematodes?
Nematodes are generally considered to be safe for use in gardens and around pets. However, it is important to use nematodes according to the instructions on the product label to avoid any potential risks.
