Things You'll Need
Instructions
Research the particular species you want to attract to learn more about the species' specific preferences for a den. Each species is slightly different.
Choose a location for the den. Foxes prefer to be close to a good water source and often like burrows with lots of surrounding grass and little other cover. Don't put the den too close to areas where humans live, as foxes can become a nuisance for humans.
Dig a space for the pipe in the ground. You only need to bury the pipe den partially into the ground. You can use a shovel, but if you want to make a lot of dens, it may be worthwhile to rent some heavy equipment, like a backhoe.
Set the pipe into its hole and cover it with dirt to form a mound. Do not bury one of the openings.
Add soil carefully around the uncovered opening. Foxes are particular about the size of the entrance, which is typically only large enough for the fox and too small for predators, like coyotes. About 12 inches is a good size for the entrance.
