Bug killer will work, but so will removing the critters by hand. You can see the eggs they are the little green dots next to the caterpillars. Whichever you feel happiest doing OL.
Sorry, scroggin.......those 'little green dots' are caterpillar faeces. The eggs are usually laid under the leaves in clusters and are yellow.
