Vine weevils

We appear to have an infestation of vine weevils on one of our trees. we only noticed them because there was alot of wasps around them. we have removed as many of them as we can and used the spray but they keep coming back and usually another batch of them appears the following day but now they are going further up the tree so that we can no longer reach them. The wasps appear very enticed by them and some of them seem to have white bits coming out of them which could be eggs. what could be causing them to attach to this particular tree which is a sally. and how to keep them away. We have issues with some of our pots having the vine weevil larvae in them. yvonneodo, Dunboyne, Co Meath Posted: 17/09/2017

It sounds more likely an infestation of dark greenfly, which is common on willow. The wasps collect sweet honeydew for food. Winter cold is likely to finish them off.

If you use half unsterilised garden soil and half compost wouy will have very few vine weevil larvae, or apply Nemasys, the nematode parasite.
