Staple the bags to the leaves so that it hangs from the tree.
Place 3 or 4 bags per tree. Staple them inside the canopy they will be in the shade.
Gently rotate and rock the vial to mix the predators evenly with the corn grits (ground up corn cobs). Do not shake the vial!
Pour out approximately equal amouints of the predator and corn grit mixture into each of the bags.
The predators will all be ouit of the bag within 24 hours, so after a few days, you can remove the bags.
If you need to hold the predators overnight after you have opened the box:
Leave the bottles with the predators in the styrofoam box.
Place the Cold-Ice bag int eh refrigerator (not the freezer!) for an hour or two.
Place the Cold-Ice bag back in the styrofoam box with a layer of foam rubber between it and the bottles.
Tape the styrofoam box shut.
Precaution: Place the bags where they will not be filled by water from the irrigation system. Bags should be oriented upward to avoid spilling their contents.
