Hi
I'm fed up killing endless numbers of eggs and caterpillars on my broccoli plants.
How much longer will this torture continue?
I would rather not use sprays if possible.

Depends what species they are. There are several possibilities, but if you're talking about the Large White Butterfly, for instance, there are two generations a year, with eggs laid in May and July. They hatch in about a week, then pupate after about a month. So they'll be gone in another month at most.
The answer, Steve, with hindsight, is always fleece!
Yes Fleece or netting on canes with empty bottles ( Or beer cans :D) so then there is no way for them to lay there eggs! PS Check for birds that may get trapped in netting.
Provention is better than cure!
