Although the product label for ZP rodent bait does not list specific restrictions on placing it near fruit and nut trees and crops, we always hesitate to recommend using products near these kind of areas.  The ZP rodent bait product label does say that when using it outdoors you should place the bait in tamper resistant bait stations or directly in rodent burrows.  Since rodents might be eating your crops and fruit trees, you have to be careful about food competition.  In other words, just because you place ZP rodent bait near other food does not mean rodents will eat it if the other food is more appealing and easier to get to.  In this situation, we would recommend surrounding the garden or crop area with rodent stations containing the bait and hopefully the rodents will eat the bait first before going into the garden or crop area.
