What temperature do bullfrogs come out?
American bullfrogs are considered warm adapted species that prefer temperatures above 26°C. (Bachmann 1969). However, it is important to note that egg development is impaired in water above 31°C (Degenhardt et al. 1996), a lower threshold than observed for native amphibian species.
How long does it take a bullfrog to get to full size?
They take anywhere between a few months to 3 years to transform into frogs, depending on the temperatures of the area, after which time they take another 2 years to become sexually mature. Bullfrogs can live for around 8-10 years in the wild, although one specimen in captivity reached age 16.
How far will bullfrogs travel?

What is the best way to catch bullfrogs?
An effective method to catch bullfrogs is to shine shorelines after dark, spot the frogs and then ease in close enough to catch them in a net or even by hand. That is a lot of fun, but I prefer to “fish” for my frogs. Bullfrogs are voracious predators; they will eat anything that does not eat them first.

Instead, bullfrogs breed anywhere from May to July in our area and from February to October in the south.
Do bullfrogs leave the pond?

Bullfrogs, however, will take up residence by a pond and can usually be seen sitting on the edge of the water.
How do I get rid of American bullfrogs?
Their lack of predators, prolific nature, and incentive to relocate make bullfrogs a difficult invasive species to eradicate. No single method has proved effective in eliminating them, according to Schwalbe. Rotenone and other toxic chemicals can be applied to ponds to effectively kill fish and frog tadpoles.
When is the best time to see a bullfrog?
