Have you figured out what they are yet? Maybe take some pics. It is kinda early for the bad bugs or for that matter the good bugs to be out at least here it is.
Another thing to remember is that if the bad bugs aren't severaly hurting your plants leave them for a bit and that SHOULD bring in the predators. If everytime you go and destroy the bad bugs you will not attract the good bugs and that could make it worse in the long run. Sounds crazy but it's true.
You could also plant small nectar producing plants to atract the good guy's. Dill, Parsley, Nasturtium, Yarrow even let you dandelions grow for a bit. Even leave a small container of water with a rock or small piece of plywood in it so the good guy's can get a drink. Yet again sounds crazy but a blanced ecosystem is what you should be striving for.
Good luck I had some bad dealings with a few pest last year, this year it's on suckers.
