I think that every garden in the country must be plagued with these awful creatures, dig them up and lay them out for the birds, how many of these insects have been imported in the vast number of plants that flown into this country every year.

I'm very familiar with vine weevils having caught and crushed hundreds over the years, but I can't say I know what their grubs look like, so wouldn't it be possible for GW to do a feature on pests and show pictures of the adults and grubs.
It would also be very useful to identify which insects are good for the garden and which aren't.

Would have been great to see a picture of both adult and larval stages of this pest on the same page as the tips.

I have used Provado on and off but I still have Vine weevils.
I believe it only works if you use it twice yearley. I do not use it now as one of the instructions is ( apply away from bees ).
Figure that one out.

The adults do like to bask in the sun on warm/hot days, easy to see them if you have a light coloured wall then just 'pop' them.
The Grubs look like fat Stuby Magotts with a amber/Brown heads.
If you find them feasting on your plant roots in a pot or container, best thing to do is get yourself one of those plastic trays used for mixing cement/concreat from b&q and empty the pot into it, Let the birds their thing

if you want to look at pic's of them best thing is to google them

I clearly have had this vine weevil thingy for 18 months now and have been using garden centre remedies but it is driving me mad and spreading round my garden. My husband and I went out in the evening a couple of times but I cannot see anything!

There must be another way to distiguish this pest!

Can anyone help! It is spoiling my plants!

something is eating large chunks of my runner bean leaves and worst still most of the flowers from the pot upwards, any ideas please
24/11/2011 at 15:28
A new Wisteria Floribunda Cascade Grated version, was put into the ground with proprietory compost and started shooting up with a vigorous grow tip. All the small young leaves at the top, 5ft up, are being eaten by something not visible - whatever is chewing is very vigorous. I am about to apply nematodes to the soil. Have tried a general purpose 'green fly' spray to no avail.
Help?

they love heuchera in pots,fesh potted plants with new loose compost,plastic planters =warmer compost
they don'tlike
established potted plants less room to lay eggs teracotta pots=colder colder compost

I have the most horrendous vine weevil problem everything was eaten last year. I have tried nematodes and provado but with little effect.  In desparation i dug up the worst ones and found the grubs , removed them the plant and soil, but to do this with my whole garden will cost a fortune.  I find it totally demoralising, is there any plants they dont like ?. I have found on the underside of the plants as well,and found them mating on the plants too, and i have actually found them indoors which is really worrying as we dont have any plants indoors.  Most of my plants were brought from garden centres where i think they are imported from abroad, could they have eggs in them?. Im not sure what to do next really the nematodes are applied twice yearly as per instructions and the same with the proado.  What  is the answer to this awful problem.

I AM HAVING DIFFICULYY FINDING A SUPPLIER OF THE CHEMICAL(IMIDACLOPRID) TO TREAT WEEVIL IN MY STRAWBERRY CONTAINERS CAN ANYONE HELP

Wikipedia says imidacloprid is sold under different brand names one of them being Provado. This is NOT for use on edible crops.

All vine weevils are female. The adults are not the real problem. They disfigure leaves by biting chunks out of the edges. They don't fly, and walk about during the night, moving from plant to plant munching and laying eggs. You can only see them at night, and the best way is to lay newspaper under a plant they are attacking and shake it. they drop onto the paper. They lay eggs several times a year, and these hatch out at irregular intervals into the larvae that do so much damage.By the time you notice the symptoms of a larval attack it is often too late. Use Provado Vine Weevil Killer as a preventative, (not Provado Ultimate Bug Killer, which is different). Don't use it on edible crops like strawberries. You need to use it twice a year as the weevils can come back 8 weeks after application when it has worn off.  

On edible crops you can use nematodes, but they only work from April to October when the soil temperature is above a certain temperature (can't remember but think it is around 5 C. The only alternative is to remove the plants in the dormant season, wash the roots thoroughly and replant in fresh compost. Remember that if you don't see larvae it does not mean there are not tiny eggs that will soon hatch into larvae. 

Because it's expensive stuff, I only use Provado on pot plants, which are much more vulnerable, and on heucheras and sedums in the garden soil. If I am overwintering pots in the greenhouse I occasionally tip them gently out of the pot, check for grubs, and then put them back. 

This is a vine weevil adult.

This is a larva (grub)

I fully agree This problem should be shown to viewers and not just mentioned. This little beetle can distroy all your hard work and anyearly stages for up and coming gardeners would be welcomed. Come on Monty get this subject covered.

my garden centre warned that overuse of the insecticide will result in build up of tolerance in the bug, and kills all the other insects too.  last autumn i used nematodes, ordered via the internet.  they had to be applied in the evening, to damp soil, and the soil had to be kept damp for 10 days thereafter, so that the nematodes could move around in the soil.  it was recommended to use the nematodes only in warm soil, in the spring and autumn.  it seems to have helped, but then perhaps our weather has been too cold for the vine weavils to hatch yet.  the garden centre advised that nematodes are not really effective unless under perfect conditions - warm, moist and friable soil.

http://www.dgsgardening.btinternet.co.uk/Insects_enemy.htm Shows each garden enemy in great detail including treatments. Also worth checking out the garden friends insects on the same site. HTH The sites page on weed seedlings images is really helpful in identifying what very young seedlings look like too.

Have a look at this site, very good pics and advice.http://apps.rhs.org.uk/advicesearch/profile.aspx?pid=234

The standard chemical treatment used to be Armillatox.  However, since the manufacturers couldn't afford the high costs of testing etc. the product is now sold for cleaning greenhouses, paths etc.  (A bit like Jeyes fluid, I suppose).

Where there is a large ornamental area to deal with, you can still used the product.  www.armillatox.com will give the dilution rates.

I have used it successfully where my rhodos and azaleas were being munched.  For pots I use Provado.  I don't (fingers crossed) have a problem with edibles.
