 hi all.
        On my cabbage and cauliflowers I have hundreds of tiny holes they are grown in a large fruit cage.
        I cannot see any eggs or caterpillars on them or any slug trails.
        Any ideas?
                       Thankyou.

 I looked up flee beatle on web and it says you can see the beatles  jumping about.
 But I have never seen them, do they see me come into the gate.

Get a piece of hardboard and spread the stickiest grease on it you can find.  Pass it over your brassicas and the flea beetles will jump up and stick to the grease.

Cheers,   Tony.
