Caterpillars. Bug Clear is a contact spray. You'd have to hit the pests to kill them. It has no residual effects.
You've got two options. Either check for them, best at night with a torch, looking on both sides of the leaves and around the stems, or spray with something like DiPel. DiPel - that's only one of the brand names - is an organic spray with Bacillus thuringiensis, bacteria derived from soil, as its active ingredient. It's harmless to everything except caterpillars and has residual properties, meaning it remains active after spraying. You need to spray both sides of the leaves.
It's also the best anti-caterpillar spray for tomatoes.
