The only downside to nematodes is you have to store in the fridge before use, but that’s nothing too onerous. More serious is the damage can becaused by the soil-dwelling larvae, which are plump, white, legless grubs up to 10mm (about 3/8in)long with pale brown heads. These eat the roots of a wide range of plants andcan bore into tubers of cyclamen and begonia, and into stem bases of cacti and succulents. They can kill woody plants by gnawing away the outer tissues of the larger roots and stem bases. Most plant losses occur during September to March, when the grubs are becoming fully grown. Vine-weevil grubs usually hatch after two weeks and immediately start to feed on the roots of their host. Fully-grown grubs burrow deeper into the soil to pupate, usually in late spring. Most adults do not emerge until the following June or July, when the whole cycle starts over again. Is the vine-weevil life cycle different indoors? Keep out of reach of children. Always read instructions before use. Wash splashes off skin immediately. Keep off skin. Do not breathe spray. Wash hands and exposed skin after use.

Weevils are a group of several families of beetles in thesuperfamily Curculionoidea, there are more than 500 species in the UK. All feed on plant material, mostly live plants but a few feed on dry seeds (grain weevils) or rotting wood. Most do not cause noticeable damage to garden plants and several species are uncommon.Vine weevil is classified in a subfamily of the known as the broad nosed weevils (Entiminae), so called because the of the broad snout (rostrum) these weevils have. There are over 100 species in this subfamily in Britain. More information on broad nosed weevils from UK Beetles. And you can also control the adult beetles with nematodes, using Nematop Adult Vine Weevil Traps. Vine weevil eggs BugClear™ Ultra Vine Weevil Killer only has approval for use on ornamental and flowering plants growing in containers. It cannot be used on the soil in the garden or on edible crops.

Vine weevils are a devastating plant pest. Suddenly otherwise healthy-looking plants wilt and collapse and no amount of watering will help them recover. The reason? Vine weevil grubs have eaten all the roots. Sprays that promise prolonged protection after spraying are dangerous to bees and other beneficial insects. The following pesticides (from by the Pesticide Action Network) contain neonicotinoids that are harmful to bees: Adult vine weevils nibble on your plant leaves at night, but it’s actually the larvae that do most of the damage by eating your roots in the soil.

The Nematop® Weevil-Stop trap can be used at the same time as Nemasys Vine Weevil Killer for a two pronged assault on the pests, which should prove to be twice as effective. However, the nematodes within the special gel need a higher temperature before they become active. It is therefore recommended the soil temperature be at least 12°C, and so May would be the ideal time to position the wooden traps. Eggs start off white, but turn brown before they hatch, making them very difficult to spot in soil. Applying Nemasys Vine Weevil Killer in March, or early spring, when temperatures are at least 5°C will stop the grubs from becoming adults thus breaking the life cycle. However, the adults will still be wreaking havoc during the nights as they fly from plant to plant laying their eggs. To ensure adults are also eliminated, place Nematop® Weevil-Stop traps from May onwards.Yes, vine weevils jump down to plants from walls, particularly in greenhouses, to land near pots. That’s why it’s important to keep infested plants away from walls. Dilute the concentrated liquid as recommended on the label and water it on to the compost in the containers. It works in the roots and the compost, where it will protect against vine weevil and other compost-dwelling insect plant pests for up to 2 months. Ornamental plants grown in containers can be treated with the systemic neonicotinoid insecticide acetamiprid (e.g. Bug Clear Ultra Vine Weevil Killer) as a liquid drench applied to the compost. This insecticide gives protection against the grubs for up four months; treatment in mid- to late summer will control the young larvae and prevent damage occurring later in the autumn to spring period. This product cannot be used to treat edible plants or ornamental plants growing in the ground The adults are active between the end of June and October. In daylight you might spot the odd one walking across the patio or on the wall of the house. If you go out at night with a torch there’s a good chance you will see them feeding on the foliage. They give a similar protection time to nematodes, and you have to mix the contents with water (concentrations vary), but you don’t have to keep it in the fridge first.

The adult vine weevils eat your leaves between April and October, which gives it the energy to lay eggs. Vine Weevil larvae are a major pest for ornamental garden and household plants. The larvae feed on plant roots causing sudden wilting or killing your plants. The larvae are most active from July to October as they feed on your plants to fatten up for over wintering, while they develop in to adults the following year. There are three ways of controlling vine weevil: chemical, biological control and physical barriers. Controlling vine weevil grubs There are now several methods of treatment available including the traditional pesticides but there are also some eco-friendly options too. Pesticides can now be considered the last resort, as they can harm the environment and also be dangerous if used in areas frequented by children or pets. So a safe, natural biological control method is one solution worth considering.Nemasys Vine Weevil Killeris both safe and highly effective in the control of vine weevil grubs. The treatment consists of natural nematodes, a tiny parasitic worm that feeds on the vine weevil larvae.The larvae survive through the winter but stop feeding. They hibernate around the roots over winter, and then form pupae in April. All prices shown below are per parcel with a maximum weight of 30 kg per parcel. Items over 30 kg are split into multiple boxes and charged per box. This is a symptom that the vine weevil larvae are eating your roots, reducing the plant’s ability to take up water and nutrients. It can be used on any plants without affecting them, including edible or ornamental plants growing in the ground (unlike insecticides).

Or you can use Zee No Weevil, a granular product applied to the surface of compost or around the base of susceptible plants. It is made from dried, crushed olive pommace (the dried leftovers from making organic olive oil) and aromatic Mediterranean herbs. Thoroughly rinse the watering can used after use and pour the washings over compost with ornamental plants in pots.You have had the goods delivered within seven working days of delivery from Future Garden Ltd, this starts from the day after the goods have been signed for. Leaf damage is visibly obvious as the adult weevils nibble at the edge of leaves, causing irregular-shaped notches in the leaf margins, during the summer months. However, root damage caused by the young larvae is not always immediately obvious. The plump, creamy white legless grubs have light brown heads and are up to 10mm long. They are likely to be found among the roots, where they feed voraciously. Some adult beetles also survive by finding sufficient places to shelter over winter, but again stop feeding until April. What do vine weevil eggs look like We waited for rain: it rained steadily for two days before we applied the vine weevil nematodes and rained again for a few days afterwards. The product is very easy to use. Getting it to the roots of large shrubs is the biggest problem. I gave a 4/5 mark because I don't know yet if all the vine weevils are dead. However, from a ease of use viewpoint, it get 5 out of 5. If only a few pots are affected, try sifting the grubs out by hand. Squash any you find before repotting the plants in fresh compost and putting the rest in the bin. What about barriers for vine weevil?
