Nematodes for vine weevil larvae

Covers an area of 50 - 100m2.

Vine Weevil is one of the most damaging pests in ornamental pot plants, in strawberries or hardy ornamental stock and fruit. The adult weevils eat plant leaves during spring and summer, but it is the grubs that cause the most damage over autumn and winter when they feed on plant roots, causing wilting, and often plant death.   Plants growing in pots or other containers, outdoors or under cover, can be severely damaged by vine weevil grubs.

  • Adult weevils cause irregular-shaped notches in leaf margins during the summer
  • The plump white legless grubs have light brown heads and are up to 10mm (about 3/8in) long. They are likely to be found among the roots.
  • Plants wilt and die during autumn to spring as a result of grubs devouring the roots

The nematode works only on the larvae - not on the adult beetle.

  • The best time to use the nematodes is late August or early September when the temperature of the soil is high. Other possible application periods – if conditions are favourable – are April and May.
  • Dissolve in water and drench soil.
  • Soil temperature must be +10 celsius or higher

Here are some important points to note -

  • All the sieves in the equipment used must be removed to prevent blockages
  • Do not expose the nematodes to direct sunlight
  • Nematodes must be mixed continually to prevent them from sinking (also when spraying!)
  • Spray the crop with water before and after application
  • Keep the soil moist for the first two weeks after application

The product can be used both in container cultivation and in open field cultivation. Please note: in open field cultivation in dry weather, the ground must be sprayed with water before using the nematodes.

We order once a week  - Orders received before 10am on a Thursday will be delivered by the following Thursday.

This is a live product - normally supplied with a 10 day+ shelf life. Please use by best before date on packet.



  1. Half an hour before preparing the product, remove the pack from the refrigerator and let it come up to room temperature (20°C)
  2. Break the contents of the sachet (250 million Heterorhabditis bacteriophora) into smaller pieces
  3. Use the entire pack and place the smaller pieces in a bucket containing five litres of water (at 15 to 20°C)
  4. Leave the bucket with the solution to stand for five minutes
  5. Then stir the solution until all the lumps have disappeared before transferring it to the spray tank
  6. Use the spray solution straight away

 Application and dosage:

  • With a watering- can, sprinkler system, backpack spray unit or vehicle-mounted spray unit
  • To avoid blockage, all filters should be removed
  • Use a maximum pressure of 12 bar on spraying boom or pistol
  • The spray nozzle opening should be at least 0.5 mm (500 microns)
  • Continuous mixing should take place to prevent nematodes sinking to the bottom of the spray tank

Best working conditions for Nematodes

  • The moisture content of the soil must be high
  • Soil temperature between 14 and 33°C
  • Nematodes are susceptible to ultraviolet light (UV): do not use them in direct sunlight
  • Leaf applications should only be carried out in the evening to minimise the influence of UV light and to maximize moisture availability for the nematodes
