Catching Guinea Pig Escapees?

Our Moma guinea pig escaped into the vegetable garden some weeks ago. This is an area of about an eigth of an acre with large shrubs and bushes, a hothouse with a jungle of foliage plants, many clumps of herbs and other plants all providing unlimited hiding places. Moma has since had babies - we see them shooting under places we have no hope of catching them from when we go into the garden. Meanwhile we have no vegetables; everything is eaten off by marauding gp's as fast as it grows.

We've tried setting a trap-door cage with bread and with apple, but of course the little varmits have plenty to eat without going into the trap.

I don't hold out much hope for a solution, but just maybe someone out there knows of something even the best-fed guinea pig couldn't resist as bait, or have some other idea of how we could catch them.
