We share Michigan with 13 frog and toad species, which play a beneficial role to both humans and wetland ecosystems. With their charming choruses and appetite for virtually any pest that crosses their path, frogs and toads can be a major benefit to yards and gardens. It is even estimated that one cricket frog devours 4,800 insects in one year.
Like many of Michigan’s amphibians, frogs are small and camouflage easily among grasses, trees and soil. But with the right tricks, you can encourage these sometimes small and cold-blooded critters to come out of hiding and take haven in your backyard.
• Take advantage of natural resources
A well-groomed yard may be aesthetically pleasing, but it isn’t supportive to wildlife. Frogs and toads are attracted to native ground cover, like tall grass and wildflowers. To welcome amphibians, leave leaf litter, logs and rock piles under trees and shrubs that provide natural shelter.
• Build a toad house
Provide a safe place for toads to take shelter by building a toad burrow or toad house. Create a depression in soil beneath shrubs or flowers. Layer stones along the side and top of the depression, about 6-8 inches high. Or, reuse an 8-inch flower pot by creating a hole big enough for a toad to fit and placing it upturned in a shady area in your garden.
• Build your own backyard pond
Add diversity to your yard by creating a pond, which is an easy ways to attract frogs, toads and other forms of wildlife. Recreate their natural habitat with vegetation like water lilies, cattails, fallen logs, ferns, wildflowers and tall grasses, which attract insects and other food for frogs as well as provide cover. Native plants and rocky areas outside of the pond serve as retreat areas for toads.
When seeking the ideal spot for your pond, choose an area on low ground and away from potential threats such as raccoons or runoff from fertilizer and pesticide use.
Ponds are best supported by clay soils and should not be built in dry, sandy soil. Ponds should be at least 12 feet long and 6 feet wide, with space for amphibians to bask along the edges of the water. Make sure the water is slow moving and shallow, about 1.5 feet deep, so that it is ideal for pond-breeding amphibians to lay their eggs.
