Nematode applicator for your garden hose
This hose-end applicator helps you treat lawns, beds, borders and vegetable patches evenly, with less lifting and pouring than a watering can. It connects to a standard click-on garden hose connector (not included) and provides a wide spray pattern, with an on/off control for the water flow.
The refillable pouch is simple to fill and top up. You can see the solution level fall as you work, then refill and repeat when treating larger areas. It is suitable for a wide range of Nematodes Direct and Nemasys nematode treatments.

How to use the nematode applicator
- 1
Mix the whole pack in 1 litre of water
Pour 1 litre of water into your bucket or bowl, add the nematodes and stir thoroughly to make a stock solution.
- 2
Fill the pouch for your treatment
Using a funnel or jug, pour in the stock solution per pouch shown in the table, then top up with tepid water.
- 3
Fit the spray head and connect your hose
Screw the spray head with its tube onto the pouch, shake gently to mix, then click your hose on.
- 4
Apply evenly over the area for one pouch
Turn on the water and adjust the flow with the tab on the side of the spray head. Follow an S-shaped path, covering the area per pouch shown below, and concentrate on obviously affected areas.
- 5
Refill, repeat and water in
When the pouch is nearly empty, gently pinch the bottom to help apply the remaining nematode solution. Refill and repeat steps 2–4 until all the stock solution has been applied. Water thoroughly afterwards.
Follow an S-shaped application path
Start at one corner and work across the area in a single S-shaped pass so every part is covered evenly.
Each full pouch should cover the area per pouch for your pest and pack size in the table below.

One pouch, refilled as needed: “Number of pouches” means the total number of filled-pouch applications from one pack of nematodes, not the number of applicators supplied.
Spring leatherjacket treatment: apply at twice the autumn rate, so one pack covers half the area. Continue until all the stock solution has been used.
Recommended application temperatures can vary by manufacturer and product, so always follow the temperature guidance supplied with your nematodes.
Get the best from your nematodes
Choose the right conditions
Nematodes are sensitive to UV light. Apply in the evening, on an overcast day or during rainfall, and always follow the treatment instructions.
Keep lawns moist
After application, keep the lawn moist with regular watering for up to 2 weeks.
Care for plants after treatment
When applying over plants, re-water after 30 minutes to wash nematodes into the soil. For pests on plants or bushes, spray directly onto the pest and re-spray often to keep the plants moist.
Repeat treatments: Flea Beetle and Box Tree Caterpillar need a second treatment one week after the first application.
Using the applicator for liquid feeds
The applicator can also be used to apply liquid feed to plants and lawns. Follow the liquid feed manufacturer’s dilution instructions. Rinse the pouch and spray head with clean water before using them for nematodes.
