Vine weevils again:(

I started examining my fuchsias for signs of starting up this spring, and yet again the roots are being chewed by vine weevils. I've repotted all the plants with green in stems, collected the vine weevil pupae and put them out for the birds, but yet again I think most of the plants will not thrive.
What do other fuchsia lovers do? I'm seriously considering Provado or a similar product but I don't like using any chemicals in the garden.

 

Try nematodes Liz they worked for me last year
