Vine Weevil nematodes are watered into pots or open ground with a watering can or hose, killing the vine weevil grubs.
Use as soon as the soil temperature reaches 5°C. The parasitic nematodes enter the grub, poisoning it and then feeding off it to increase their numbers.
Sold in 2 sizes.
Biological controls are not always kept in stock, they are ordered in fresh. This can sometimes lead to a time lag between when you place the order and when it is despatched. Order by 10am Monday for same week despatch.
