Newby, no Bug Ultra clear will not work on vine weevils. Provado is the only effective chemical for the grubs. at night grab a torcb and check walls and plants for the asults. evergreens like eunymous seem popular with them. Be quick cos they will drop at the slightest disturbance. Squash 'em!
vine weevils do most damage on heucheras, primulas, fuschias by eating the roots so nothing remains. MPC too has been a boon for vine weevils so using john innes compost instead helps.
the vine weevil population here is now far less than it was... Thanks to .a combination of Provado or nematodes (cannot uss both), nighttime vigil and soil based compost
