Juanse,
Just as a point of reference I typically collect pollen with Sundance bottom traps during the month of June. Normal daily catch is 4 to 8 ounces ea. (112 - 224 g) with an occasional one up to 10 oz. So it seems to me you must be in a pollen dearth or have leaky traps. The girls will go around if they can figure out how. By watching an entrance for a while you should get a sense of how much pollen is coming in with and without a trap.
