What are Vine weevils? 

Vine weevils are troublesome beetles recognized for their impact on gardens. These adult insects are a matte black color and measure around 9 mm in length. Although they lack the ability to fly, they are skilled climbers. They pose a significant threat to plants in containers, as well as those planted in the ground.

Adult vine weevils munch on leaves, creating notched edges, but the most severe harm is caused by their larvae. These larvae are creamy white with tan-brown heads and reside in the soil, where they consume plant roots. This root damage can lead to wilting, poor growth, and even death of plants, particularly during the autumn and winter months when the larvae are most active.

When should I apply vine weevil nematodes?

Apply nematodes between late spring and early autumn or when the ground temperature is above 10°C (50°F).

How do I apply nematodes for vine weevil?

Mix the nematodes well according to the instructions on the packaging. Locate the centre of the ant nest and directly apply the nematodes using a handheld sprayer or a watering can.
If it is not raining, irrigate the treated area afterwards to keep the soil damp for at least two weeks.
Full instructions are also on the back of the packet.

Facts about Vine Weevil nematodes

Effective Biological Control: Nematodes, particularly species like Steinernema kraussei and Heterorhabditis bacteriophora, are highly effective at controlling vine weevil larvae. They enter the larvae’s bodies, release bacteria that kill the host, and then reproduce inside them.

Application Timing: For best results, nematodes should be applied in late spring or early autumn when soil temperatures are warm enough (between 12-20°C) for the nematodes to be active.

Moist Conditions: Nematodes thrive in moist soil conditions. It’s important to keep the soil or growing media moist before and after application to ensure the nematodes can move and find the vine weevil larvae.

Safe for Plants: Nematodes are safe to use on all edible and ornamental plants. They do not harm plants, humans, or pets, making them an environmentally friendly option for pest control.

Long-Lasting Control: Once applied, nematodes can provide long-lasting control of vine weevil larvae, helping to protect plants from root damage and ensuring healthier growth.
