how do you destroy box blockers

Question

A box with a pointer that moves how do you stop it from making mesh cages I have tried everything but nothing stops or blows them up

I saw this answer earlier which explains how to deal with them. It looks like you can use the line blast booster or create matches next to them to blow up the other cage and stop them from changing more blocks.
