SuperNemos is a biological pest control solution for your fruit and vegetables and ornamental plants. It has been specially formulated using nematodes, which are organisms naturally living in the soil to actively seek out and target a variety of pests in your garden.

Targets include;

Vine weevils, Scarid flies, Strawberry root weevil, Chafer grubs, Leatherjackets, Wire worms, Cutworms, Cabbage worm, Fungus gnat larvae, Beetle larvae, Ants, Processionary Caterpillars.

SuperNemos are completely safe to use around vegetables, plants, pets and people. Using SuperNemos will also help to develop a richer, healthier soil containing beneficial organisms.

You can apply SuperNemos in a variety of ways; sprayers, watering cans, hose‐end sprayers, and even via injection into irrigation systems.

Results should be seen between 3‐7 days for caterpillars, cutworms, army works and sod webworms. For grubs and weevils feeding stops within 3 days and maximum control is achieved within 2‐4 weeks.

 How do SuperNemos work

TIP: Your nematodes are busy working their magic, unseen under the soil. If you want to see proof you can sprinkle some live mealworms (available at any good fishing outlets) on the soil in a contained area and see how they are affected by nematode action.

SuperNemos nematodes are applied to the soil, and live in the soil where they locate their hosts. The nematode infective stage enters the insect and begins to feed on its blood and internal organs. Soon after it begins to feed, it releases unique bacteria which it carries internally. Those bacteria infect the insect, reproduce quickly, and kill the insect within 30 to 48 hours.

The nematodes thrive upon this food, which becomes available as the decaying insect is broken down by the unique bacteria.

The nematode forms an adult stage and begins to produce thousands of eggs. These eggs mature and about 2‐3 generations of nematodes are produced in the decaying insect.

Reproduction continues until the nematodes sense that the decaying insect will not support further reproduction by the nematode.

At that time, all of the nematode offspring mature only to the infective juvenile stage and begin to emerge from the host insect to look for more viable live insects to infect. The infective juvenile, IJ3, is the third nymphal stage of the nematode. It has a double thick skin, which is best equipped to survive in nature until it can find a new host.

SuperNemos Bio-Insecticide - Medium 1090-3897


You will require: 1 x 8/10 litre bucket, 1 x 1 litre measuring jug and 1 x 8 litre watering can, fitted with a coarse rose if applying to pots or turf. Ensure that you have read the important notes section below before applying SuperNemos.

1. Add 2 litres of water to bucket, add SuperNemos and rinse all residue from pack into the bucket. Top up with water to 8 litres.

2. Stir it very well and let stand for 30 minutes ‐ this is your stock solution.

3. Using the measuring jug, transfer 1 litre of the solution to your watering can and top up to 8 litres.

4. Apply this solution to 8‐10m2 (40‐50 pot plants or 15 gro bags).

5. Repeat step 3, stirring each time prior to transferring stock solution to your watering can, until the stock solution has gone. 



Nematodes require moisture in the soil for movement ‐ if conditions are dry, water the soil or compost 1 day prior to the application of SuperNemos and water again following application.

Regular watering helps the juvenile nematodes to move deeper into the soil; water pots and containers as normal but avoid overwatering.

Local conditions may affect timing of application set out in the pest guide ‐ soil and compost temperatures must be over 10°C.

Do not apply when heavy rainfall is forecast, as nematodes may be washed away from the base of the plant.

Nematodes should be applied directly to the soil or compost at the base of the plant or in the case of turf evenly over the area. 


Medium 25 million pack - Single Application 50 sq.m. Split Application 100 sq.m. 

Single Applications will remove all pests with one application.  This is particularly important when treating vine weevils and palm stem borers 

Split Applications are preferred by some gardeners as when you apply the split dosage you can ensure a long lasting results.
