Supposed to? No.

Some pull them as they only want the males, don't want the bed to get over-crowded, and they don't want to have to deal with asparagus beetles. Others leave them, let the berries fall and sprout new plants.

It's your choice.

So, asparagus beetles only like the females? I didn't know that!
How do you tell the males from the females? Nancy

No they don't only like the females but it is the berries on the females that attract them to the patch and keep them there. The berries are what they feed on primarily.

All male plant beds have a much lower incidence of gus beetles.
