Can anyone tell me if vine weevils move from plant to plant ? If i find them on the roots of a plant in pots , i can see they would move to all the others in the pot ,but does the same thing happen in the beds and borders? Will the whole border be at risk ?

The adults walk to where they want to lay their eggs and these hatch to the horrible grubs that eat the roots , so yes they move , They do seem worse in pots
I read something a while ago and it said that the adults can travel upto 5 miles a year.
They are all females, so lots of grubs! I killed two weevils last week, one munching on a Hebe cutting, but was hiding on the side of the pot and straight after there was one in the sink!
They are worse in pots, I have redone all my pots and nearly every single pot had grubs in. I did find some in an area I dug up but there were only a few grubs. Try to keep on top of things or you could find yourself in my situation with being over run with them. You can buy stuff in the shop's to kill the grubs.
I'm sorry ... every time I read the heading of this thread my mind automatically goes to 'another type of movement'
(blame the fact that I used have to write about the health of children).
I suppose I should be thankful that we don't have to get into the hygiene habits of weevils ................... do we???

The grubs do less damage in the garden than they do in pots. They eat in a straight line so do not normally completely remove all the roots from one plant. In a pot they are forced to go round and round consuming all the roots.
The grubs themselves do not migrate from one pot to another.
The all female adults do wander about like any other insect, looking for food and egg laying places.
They lay their eggs at the base of a plant stem on the soil and the tiny grubs then burrow downwards. They will not lay their eggs if they cannot reach soil with their ovipositor (egg laying tube). On single stemmed plants you may be able to prevent this by putting a 2 inch deep layer of small gravel or grit on the plant pot surface.
Hope this helps.
LOL Dove, you have now made me think back when my child had rotavirus, not nice at all
Thanks Berghill, that is a good bit of information.
Oh Lorna
Wonky had something similar when she was small ........... not nice

Dove it was that bad he had to be quarantined in hospital, not something I want to smell again, lucky he was under two and doesn't remember any of it.
Thank you everyone , especially Berghill , i really wanted to know if i found them in the garden would they move from plant to plant like they do in pots , and whether the whole bed could become vulnerable .
