tweezers work well for the task, or needle nose pliers

Since they're mostly nocturnal, they can be hard to find. Another thing your friend can do is spray his plants with the original form of Bt, Bacillus thuringiensis kurstaki. It is one of the safest pesticides you can use. It affects only caterpillars, and only caterpillars that eat the sprayed parts of the plant, which your friend should do in the evening. It is sold as "Dipel", "Thuricide" and "Green Step," among other brands.
