just a suggestion.
Go to your local vet / doctor, hopefully you have a good relationship. Ask for a syringe and a needle. if you get one your in business. fill syringe with roundup inject the little dears and watch it die.
Not an orthodox method but worth a try?? it gets you past the waxy leaves. time consuming yes. Will it work? It should do.
Please be very careful with the needle.
There are gardening alternatives to the needle bus as the stem is not over thick?
