Entomopathogenic Nematodes for Control of Insect Pests Above and Below Ground

Insects are a common nuisance in both agricultural and urban sectors. In agriculture, they can damage crops and spread disease. In urban areas, they can invade homes and cause health problems for residents. There are many ways to control insect pests, but entomopathogenic nematodes are the most effective. These tiny, worm-like creatures kill insects by infecting them with bacteria. They are safe to use and are very effective at controlling a variety of common insect pests. This blog post will explore how entomopathogenic nematodes work, what kinds of insects they can control, and where you can buy them. This article also provides some tips on how to use them for maximum effectiveness.

Entomopathogenic Nematodes

What are Entomopathogenic Nematodes?

Entomopathogenic nematodes are parasitic worms that attack insects and live in the soil. These nematodes are used for the biological control of pests, as they are safe for humans, animals, and plants. Three types of entomopathogenic nematodes exist Steinernema, Heterorhabditis, and Neoaplectana. Steinernema is the most common type used for pest control, as it is effective against many insects. Heterorhabditis is specialized for controlling caterpillars, while Neoaplectana is effective against grubs.

When an entomopathogenic nematode encounters an insect, it enters the body cavity and releases bacteria into the host. The bacteria multiply inside the host, causing death within a few days. The host’s body then provides food for the developing nematodes. There are several advantages to using entomopathogenic nematodes for pest control. Firstly, they are environmentally friendly, as they do not use chemicals.

In addition, they can be applied directly to the soil where pests are active, making them easy to use. Finally, they can be stored and shipped easily, making them readily available for use when needed. Entomopathogenic nematodes are parasitic nematodes that infect and kill insects. They are a natural form of biological control and can be used to control various insect pests, both above and below ground.

Entomopathogenic nematodes can be applied to both soil and plants. However, they are most effective when applied early morning or evening. Nematodes can be applied using a hand-held applicator or through irrigation systems. Once applied, entomopathogenic nematodes will seek out their host insects. They can travel through soil pores and plant tissue to reach their hosts. Once they find an insect to parasitize, they enter through natural body openings or penetrate the insect’s body surface.

Entomopathogenic Nematodes in Pest Management

  • Entomopathogenic nematodes are a type of nematode that parasitizes and kills insects. They are used in pest management to control various above and below-ground insects.
  • There are several advantages to using entomopathogenic nematodes for pest control. Firstly, they are environmentally friendly and effective against various insects. In addition, they can be applied easily and have a long shelf life.
  • To be effective, entomopathogenic nematodes must come into contact with their host insect. This can be done by spraying them onto the soil where the insects live or injecting them directly into the insect’s body.
  • Once inside the host insect, the entomopathogenic nematodes release bacteria that kill the insect from within. The entire process usually takes about 48 hours. So, if you’re looking for an environmentally friendly and effective way to control pests, entomopathogenic nematodes are a great option.

What is the purpose of entomopathogenic nematodes?

Entomopathogenic nematodes are parasitic worms that kill insects. They control pests above and below ground, including beetles, ants, cockroaches, and termites. Nematodes are safe for humans and animals and do not harm plants. Entomopathogenic nematodes (EPNs) are parasitic roundworms that kill insects. They are found naturally in soil and attack many insect pests, including those that damage crops above and below ground. EPNs are safe for people, pets, and the environment and can be an important tool in IPM (Integrated Pest Management) programs.

There are many different species of entomopathogenic nematodes, each with its preferences for temperature, moisture, and type of insect host. Some common species used for pest control include Steinernema carpocapsae, Steinernema feltiae, Heterorhabditis bacteriophora, and Heterorhabditis megidis. Application methods vary depending on the target pest, but most EPNs can be applied using a standard garden hose-end sprayer or backpack sprayer. For best results, applying EPNs when the target pests are actively feeding is important. 

How do they control insect pests?

There are many ways that entomopathogenic nematodes can control insect pests. One way is by parasitizing the insects and feeding on them, which will eventually kill their insect. Another way is by releasing toxins that will kill the insect. Some entomopathogenic nematodes can also transmit diseases to the insects, which will make them more susceptible to other predators or parasites. Finally, some entomopathogenic nematodes can produce chemicals that will repel other insects from entering an area. You can do several things to control insect pests using entomopathogenic nematodes. Here are some tips:

  1. Use a nematode sprayer to apply the nematodes directly to the soil around your plants. This will help to target the pests where they live and breed.
  2. Apply nematodes early in the season before the insect pests can become established.
  3. Introduce beneficial predators into your gardens, such as ladybugs and green lacewings, which will help to keep populations of insect pests under control.
  4. Use physical barriers such as netting or row covers to prevent insects from getting to your plants in the first place.
  5. Keep your garden clean and free of debris, which can provide hiding places for insects and their larvae.

Entomopathogenic Nematodes

What are the benefits of using entomopathogenic nematodes?

Entomopathogenic nematodes are an environmentally friendly option for controlling many insect pests. They are parasitic worm that infects and kills insects by entering their body through natural body openings or by piercing the insect’s exoskeleton. Once inside the insect, the nematode releases bacteria that cause disease and death.

There are many species of entomopathogenic nematodes, each with its specific host range. This makes them very effective at targeting specific pests while leaving beneficial insects unharmed. In addition, they can be used to control above-ground and below-ground Insect Pests, making them a versatile tool in Integrated Pest Management (IPM) programs. Some of the benefits of using entomopathogenic nematodes include the following:

  • They are safe to use 
  • They do not harm beneficial insects
  • They can be applied directly to soil or foliage, making them easy to use
  • They remain active in the soil for long periods, providing prolonged control
  • They are relatively inexpensive

How can I get started using entomopathogenic nematodes?

Entomopathogenic nematodes may be the answer if you’re looking for a way to control insect pests both above and below ground. These small, parasitic worms can be purchased online or at some garden stores and are relatively easy to use. Here’s a step-by-step guide to getting started with entomopathogenic nematodes:

  1. Choose a location for your nematode application. Entomopathogenic nematodes are most effective when applied to moist soil, so choose an area with plenty of water.
  2. Mix the nematodes with water according to the package directions.
  3. Apply the mixture to the soil using a watering can or hose-end applicator.
  4. Water the area thoroughly after application to help the nematodes penetrate the soil and find their way to their insect hosts.


As you can see, entomopathogenic nematodes are a valuable tool for controlling insect pests both above and below ground. If you have a problem with pests in your garden or home, consider using these helpful creatures to get rid of them.
