Holes suddenly appearing in hydrangea leaves

When I have that sort of problem it is usually small beetles that like to attack at night. Difficult to see during the day. Spray with a bug killer

Exactly. That is why it has to be the Greater Mottled Amazonian Razor Backed Beetle
 
Update

Have sprayed both plants with some bug repellent, including underside of leaves.

Will monitor and report back.

Product doesn’t mention frequency. Would you advise daily?
 
We have had a invasion of these little buggers.
Apparently alder leaf beetles.
Thought to be extinct in this country re discovered in 2004 now covering fair bit of country.
They have attacked our fruit

trees this one was chewing on a rose!
 
A weekly spray for 2 or 3 weeks should do it. I sometimes used soapy water spray as the bugs dont like it and its kinder to the environment and friendly bugs. If it doesnt work I spray with bug clear and annihilate them :D

The swine! I tend to find them lurking among grass roots, buttercup and anything where they can hide out - i like to pin 'em with me dobber but if blackbird is nearby let 'em run into their hungry beak. Blackbird likes 'em crunchy! :mrgreen:
