    Hi all. I hope everyone is doing ok during this strange and upsetting time.

    Just spotted these little sh*ts on a couple of my maples.

    What can I do?

    Thanks in advance.

    Luke.

    Hi Luke, need a photo to see what it is. If Vine weevil they are small white grub like, they eat the roots causing premature death to potted maples. The adults eat the leaves and are about 9mm in length dull black colour and have yellow markings. But they tend to appear in Summer.
    I have used Nematodes in the past which has worked well. But these are applied in the Autumn.

    Upload a photo so we can make a better informative decision on what you have.

    I’ve never had problems with vine weevil until last year which is the first time I’ve seen them in our garden. They decimated around 40 Heuchera divisions that I had taken.
    So I’ve been concerned if they attack maples and am hoping this is not the case?
    Now I have them in the garden, I guess they are here to stay.
    Is it just young maples that are affected?

    Hi Jaybee63, not just young maples but they are more susceptible due to the amount of roots they have. Nematodes really did the job for me, I use them every Autumn 'without fail' in all pots.

    Thank you Acerholic. I will keep an eye on my potted maples. Any issues with planted in open ground?

    Sorry. Silly me.

    They are tiny, like a couple of millimetres..

    Hi Luke, that does look like Vine weevil, not 100% but fairly certain. The adults attack the leaves in Spring and Summer but don't do as much damage as the grubs.
    You need to pick them off if possible and destroy or use a pesticide. (Bug Clear Ultra).specific for vine weevil.
    Have a look at the RHS website on control methods for vine weevil. It shows the biological method as you have children. Good luck.

    Thank you so much. I will do some research. Then I will look in to Nematodes to use this Autumn.

    Hi Jaybee63, I've never had a problem with Vine weevil in open ground ,'only in pots'. The adults emerge from the compost and seem to stay on the host plant. (Most of the time). If you do have a lot of maples in pots, put Nematodes on your calendar to buy in September.

    Hi. Might they be aphids?

    I always have problems with aphid infestation on the new unfurling shots every year on certain maples.
    I sometimes spray, but they usually disappear once the new growth starts to ripen.

    To me they look like aphids. They sometimes infest some of my maples when they leaf out.
