If mosquito larvae can hatch in 1 to 3 days under optimal conditions, then it is entirely possible that the waterer is getting dumped as regularly as the OP says. If she goes out early on Monday morning and dumps and cleans the waterer, then later Monday morning Mama Mosquito comes along and lays her eggs, there could well be a fresh crop of wigglers by Tuesday or Wednesday. I would certainly think that an open water source of any kind in Texas would be considered "optimal conditions.." I have a bird bath for my little visitors and forgot to put mosquito dunk in it when I scrubbed it and put in fresh water last time. I had wigglers within two days, and Northern Wyoming is a far cry from Texas. The adult mosquitoes you saw when you lifted the cover off your waterer might not have been fresh hatched, but a swarm of the little boogers who found a source for laying eggs. When I had my little pond, sometimes I'd see those swarms just above the pond surface. Didn't mean they'd just hatched - again the pond had a generous helping of Mosquito Dunk on it - but just that they'd found a water source.
I would definitely switch to a bucket with horizontal nipples. I've been really happy with mine. The cover is on, and except for the tiny hole at the top where my water level indicator comes out, there are no openings into the water. You might try that. Costs a bit in the beginning for the bucket and the nipples, unless you score a free bucket from your local bakery or deli, but well worth the investment. I'm so paranoid about leaving places for mosquitoes to multiply that I have mosquito dunk in the old tires on the roof of our house. (Tires keep the roof on this old mobile home from rippling in the wind)
