A few embellishments that make all the difference: Lay the tarp flat on the ground near the nest. Fold a few inches of the ends of the tarp up and over, all around the edge, then weight down with rocks, soil or sticks. This makes for a few inches (4"-12", depending upon the size of the tarp) of shade all around the tarp. Note that ants running from the center would encounter the walls, then mini roof on their way out of our trap. Scatter the debris across the center. Don't have to dig deep in summer as their young are fairly close to the surface whenever it is hot out. Better to use a shovel, improvised or otherwise, though bare hands can work with some species if you're quick. Good luck digging for the queen. Most eggs, etc are not in her chamber for long anyhow. She's tasty if you can find her though! Result? The ants move the eggs, larva and pupae out of the sun... and underneath our little porch area all around the edges. Hint: they leave all of the debris behind. Thus doing all the work for you. Simply scoop around the outside of our tarp until all of those lil tasties are in our pan, then fry. (Important: leave them covered until ready to scoop!) Taste depends upon the species, oil (If any. Water works too.), seasoning (if any) and length of cooking time. Typically they taste like shrimp (cooked less) or nutty (cooked longer) .
