How do you turn cracks white?

[Joshua12450]

The little blue cracks on the ground in some levels are really annoying. Some I cover with anticreeper for minutes on end, yet they stay blue and damage anything i try to put there. Others stop producing creeper pretty much as soon as i clear it off them. Is there a specific thing i'm missing?

there are two types of blue "cracks"

Mesh: https://knucklecracker.com/wiki/doku.php?id=cw4:info:mesh

It conducts creeper (and anti-creeper) when active (blue). It can be killed by units (Cannon or mortar) with sustained fire. It is nourished and grows from an emitter placed on the mesh, so if the emitter is nullified, it'll stop growing.

Creeper breeder https://knucklecracker.com/wiki/doku.php?id=cw4:info:breeder

it's also blue and it'll never change color. If any creeper is present on it, it'll "breed" it according to the settings for that particular patch.
