Frequently asked questions – Lawn Flea and Flea Beetle Nematodes 

What are lawn flea and flea beetle nematodes and how do they work?

Lawn flea and flea beetle nematodes are a mix of beneficial microscopic organisms (Steinernema feltiae and carpocapsae) that target flea and flea beetle larvae in the soil. They help reduce pest numbers naturally by interrupting the lifecycle before adult emergence.

When should I apply nematodes to control fleas and flea beetles?

Apply the first treatment as soon as pest activity is detected. Use the second application 5 to 7 days later to stop newly emerging larvae. Apply in the evening, when soil is moist or rain is forecast.

How do fleas and flea beetles affect my garden and lawn?

Fleas can latch onto pets and be carried indoors, becoming a home infestation risk. Flea beetles damage plants by creating small, irregular holes in leaves, especially on brassicas and ornamentals.

What do flea beetles look like and how do I spot an infestation?

Adult flea beetles are small, metallic black, blue or green insects about 2 to 3 mm long. They jump when disturbed. Leaf damage appears as shallow pits or holes with brownish scar tissue.

Can I use flea nematodes safely around pets and wildlife?

Yes, flea nematodes are safe to use around pets, people, wildlife, and pollinators. They specifically target flea and flea beetle larvae in soil and do not affect beneficial insects.

How do I apply lawn flea and flea beetle nematodes?

Mix the nematodes with water and apply to moist soil using a watering can or hose-end sprayer. Keep the area moist for three to four weeks following application to maintain effectiveness.

How much area does this nematode pack cover?

Each pack includes two treatments for a total of 25 square metres. For larger areas, additional packs will be required. The nematodes can also be split into smaller applications if needed.

What is the best time of day to apply nematodes?

Apply in the evening, on cloudy days, or when rain is forecast. This helps protect the nematodes from direct sunlight and increases their activity in the soil.

How should I store the nematodes before use?

Store the nematodes in the refrigerator or below 5°C and use before the expiry date printed on the packaging. Do not freeze or expose to high temperatures.

What happens if I don’t apply the second treatment?

Skipping the second application may allow new larvae to emerge and re-establish the infestation. For full coverage, both treatments should be used as directed within 5 to 7 days of each other.
