Vine weevil


Holes and notches chewed out of leaf edges, roots damaged, plant suddenly wilts and dies.

Find it on: many plants, container-grown plants are especially vulnerable
Time to act: all year round


Both the 1cm-long black adults and 1cm-long plump, white, legless, brown-headed larvae are a problem. The latter hide in the soil, and feed on roots (severing them) and bore into tubers from autumn to spring. Container plants are most at risk. The adults have six legs and a pair of antennae, moving in the open at night, chewing the edges of leaves. This isn't itself a problem, but the fact that each adult is a female, laying almost 1,000 eggs in summer, is alarming.

Go out at night with a torch and pick off the adults. To kill the larvae, in August/early September treat the compost with a predatory nematode, which is sold by mail order.

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
