Vine weevil larvae are among the most destructive garden pests for container plants, ornamentals, ...Vine weevil larvae are among the most destructive garden pests for container plants, ornamentals, fruit crops and greenhouse collections. Because they feed on roots beneath the soil surface, infestations often go unnoticed until serious damage has occurred. These Vine Weevil Nematodes contain Heterorhabditis bacteriophora, a natural biological control that targets the damaging vine weevil larvae in the soil. Once applied to the soil, the nematodes move through the root zone in search of larvae. When they find a host, they enter the body and prevent it from feeding further. As they reproduce, they continue spreading through the soil, providing long-lasting protection. They are mixed with water and applied directly around the roots where the larvae feed. Ensure the soil is moist before and after application to help the nematodes move through the soil. They can be applied to pots, containers and open ground. This pack treats 12 sq.m. Nematodes are a live product and cannot be returned. They usually have an expiry date of around two weeks and should be stored in the fridge on arrival.

FAQs
Are these nematodes safe for pets?
Yes, these are natural biological controls and are safe to use in gardens where pets and children are present.
Can I store the pack in my shed?
No, they must be stored in a refrigerator to remain viable. They are a living product and cannot survive high temperatures.
How soon do I see results?
The nematodes immediately begin searching for larvae and stop them from feeding. Visible signs of plant recovery will depend on the extent of previous root damage.
Can I use these on vegetable crops?
Yes, they are safe for use on edible fruit and vegetable crops.
How often should I reapply?
Reapplication may be necessary if you have a recurring infestation, typically following the specific seasonal life cycle of the vine weevil.
Troubleshooting
Nematodes were left out of the fridge for several days.
Nematodes are live organisms; if they reach ambient temperatures for too long, their efficacy will drop significantly. Use them immediately, but effectiveness may be compromised.
Plants continue to show signs of wilting after treatment.
Ensure the soil moisture levels are maintained. Nematodes cannot move through dry, parched soil. Also, verify that the damage is indeed from vine weevil larvae rather than root rot or water stress.

Setup, Compatibility & Care
Storage: Upon arrival, keep the package in a refrigerator until you are ready to use it. Do not freeze the product.
Mixing: Follow the specific dilution rates provided in the packaging to create your application mixture.
Application: Apply the mixture during early morning or late evening to avoid direct sunlight, which can harm the nematodes before they enter the soil.
Moisture Maintenance: Pre-water your soil before application and keep it moist for at least two weeks afterward to support nematode migration.
Compatibility: Avoid applying chemical pesticides concurrently with nematodes, as these can kill the beneficial organisms.
