Frequently Asked Questions

Beneficial nematodes are microscopic organisms that naturally live in soil and target harmful insects. They seek out pests, enter their bodies, and stop them from reproducing, helping restore balance without chemicals.

Yes. They are safe for people, pets, plants, and pollinators. They only target specific soil-dwelling pests and do not harm beneficial insects like bees.

No. They are designed to be easy to apply using basic watering equipment. Most customers use them successfully without any prior experience.

Beneficial nematodes actively search for suitable pest hosts in the soil or growing media. Once they find them, they enter the pest and begin their natural control cycle, helping reduce the population over time.

No. Beneficial nematodes are microscopic, so you normally cannot see them without magnification.

No. Beneficial nematodes are a biological solution used to control certain pest insects naturally.

Mix the nematodes with water and apply using a watering can, sprayer, or irrigation system. Keep the soil moist before and after application for best results.

Apply early morning or evening to avoid direct sunlight. Soil temperature and moisture play a key role in effectiveness.

This depends on pest pressure. For active infestations, reapply every 7–14 days. For prevention, seasonal applications are usually sufficient.

Yes. Moist soil helps nematodes move more effectively and improves contact with target pests. Avoid letting the treated area dry out too quickly after application.

Yes. Cloudy conditions are often helpful because they reduce exposure to direct sunlight. Light rain can also be fine, as long as it does not wash the application away immediately.

Yes. Beneficial nematodes are commonly used indoors for issues such as fungus gnats in houseplants or growing media.

Yes. They can be applied in containers, raised beds, gardens, lawns, and many commercial growing environments, depending on the target pest.

You can often apply beneficial nematodes with a watering can, compatible sprayer, injector, or irrigation system. The right method depends on the product format and the area you are treating.

They begin working after application, but visible improvement depends on the pest, infestation level, and environmental conditions. Consistent use and proper timing help improve results.

If using our patented non-refrigerated nematodes, store them at room temperature, away from direct sunlight. For our other nematode products, keep them refrigerated until use. Do not freeze or expose them to high temperatures.

Our patented non-refrigerated nematodes come with 6 months of shelf-life. Our other nematode products should be used within a few weeks of purchase for best performance.

No. Beneficial nematodes should not be frozen unless a specific product instruction says otherwise.

Short exposure is not always the same as product loss, but prolonged heat and direct sunlight should be avoided. Store the product properly as soon as possible after delivery.

For best performance, mixed nematode solutions should generally be used promptly after preparation rather than stored for later use.

No. Shelf life depends on the product format and how it is designed to be stored, so always check the product guidance for the specific item you purchased.

Yes. They are highly effective against fungus gnat larvae in soil and growing media.

Yes. Our products contain a mix of certain nematode species that target lawn grubs and help reduce damage to turf and roots at a fast rate and high effectiveness.

They significantly reduce pest populations and prevent future outbreaks, but results depend on conditions and proper application.

They can help target the soil stage of certain thrips life cycles, making them a useful part of a broader control program.

Yes. Different nematode species or product blends may be used against a range of target pests, depending on the application and product type.

Beneficial nematodes are generally most effective against pests that live in soil or growing media, or that have a soil-based life stage.

You may still see adult insects for a period of time, especially if the treatment is targeting the soil stage of the pest. Reapplication and overall pest pressure also matter.

Correct pest identification, proper timing, adequate moisture, and following the product directions closely all help improve results.

Yes. Beneficial nematodes are widely used in environments where people and pets are present.

Beneficial nematodes are used to target specific pests and are not intended to harm bees or pollinators.

Beneficial nematodes are intended to target specific pest hosts. They are commonly used as part of a more balanced biological approach.

They work well as part of an integrated pest management program. Avoid applying them alongside harsh chemicals that could reduce effectiveness.

Yes. Beneficial nematodes are commonly used within integrated pest management programs to support a more complete control strategy.

No. Beneficial nematodes are used around plants and root zones without damaging the plants themselves when applied properly.

That depends on the product and application method. When combining inputs, it is best to avoid anything that could create harsh conditions for the nematodes.

Yes, they can be applied through irrigation systems in many hydroponic setups, depending on filtration and system design.

Yes. Nematodes are widely used in commercial agriculture and greenhouse production with standard application systems.

Yes. Beneficial nematodes are commonly used in greenhouse settings for pest management in growing media and root-zone environments.

Yes. Depending on the target pest and product used, beneficial nematodes can fit nursery, landscape, and turf programs.

Yes, many commercial applications use irrigation-compatible methods. System design, filters, screens, and product handling all matter.

Yes. Many growers and commercial users apply beneficial nematodes as part of a scheduled preventive or rotational strategy.

Yes. Accurate pest identification improves product selection, timing, and overall results.

You can use our Find Solutions page to narrow down the right option, or contact us if you need help choosing based on the pest, crop, or application area.

Yes. If you need help with product fit, application approach, or general guidance, please contact us.

You can browse through our shop collections to explore products by use, category, or application need.

Yes. EFI supports both retail and commercial applications, depending on the product line and use case.

You can explore our educational content, product pages, and solution-based pages to better understand how each option fits your needs.

It helps to share the pest you are dealing with, where it is happening, what crop or area is affected, and anything you have already tried. That makes it easier to guide you to the right solution.
