The native Polistes aurifer. (golden paper wasp) frequently. overwinters in attics of homes. The queens emerge during the. first warm days of spring (as. early as March and April), select. a nest site, and build a small. paper nest in which they lay.
The length of incubation (or amount of time it takes for eggs to hatch) depends a lot on weather conditions. Temperature, humidity, rainfall, and other factors influence incubation. Generally, land turtle incubation ranges from 45-90 days (I know that's a long time to wait when you want to see baby turtles!). I suggest you start checking on the nest every couple days starting at the six week point. I wouldn't expect to see any babies until August at the earliest.
Heat the eggs slightly cooler at 68 degrees and all of the eggs will hatch as female turtles. Set the temperature slightly warmer at 73 to 75 degrees and the baby turtles will end up as male. At the middle temperatures you get both male and female turtles.
