If the others are small enough, some types of frogs may even eat them. In many species, such as gray tree frogs, the males become territorial around the breeding season and may fight with other males while seeking the company of receptive females.

Frogs can change their sex even in pristine, pollution free settings. They found more female frogs than males in suburban areas. But now a new study by the same scientists finds that green frogs (Rana clamitans) change sex even in natural, unadulterated settings relatively free from human-caused pollution.

Males and female frogs often have slight differences on their hands and feet. Male frogs often have small differently coloured and/or more roughly textured patches on their hands, especially on the insides of their thumbs. Often tricky to see, in the breeding season they often turn dark and become raised.

While we pay more attention to reptiles as a source of Salmonella, the risk is also present with frogs, and the best thing is to do is assume that all frogs are carrying this potentially harmful bacterium. Hands should always be washed after touching a frog, and no one should ever kiss a frog.

In Japan frogs are a symbol of Good Luck, and the Romans believed that to have a frog would bring good luck into the home. For many cultures that depend on rain for rich and bountiful crops the frog is a good luck symbol, a sign of prosperous weather to come. Your frog totem can thrive both in water and on land.

Studying how Roundup® affected frogs after metamorphosis, Relyea found that the recommended application of Roundup® Weed and Grass Killer, a formulation marketed to homeowners and gardeners, killed up to 86 percent of terrestrial frogs after only one day.

Frogs exposed to commonly used pesticides in the lab had mortality rates between 40-100%, according to a new study in Germany. “It is the simplest effect you can think of: you spray the amphibian with the pesticide and it is dead. That should translate into a dramatic effect on populations.”

The humane way to terminate the toads is to apply a small dab of Orajel or a similar numbing agent on it while wearing latex or rubber gloves. After a few minutes, place them in a plastic bag and freeze them for 48 hours. Then dispose of them.

Most frogs are freshwater creatures, so spraying areas of your yard with salt water also will discourage the frogs. Vinegar can be useful, too. However, coffee grounds, salt and vinegar can harm your plants, so use caution.
