Eliminating rock piles, brush piles, tall grass, etc. will cause snakes to seek a more suitable habitat. Lumber, wood piles and other debris around the home should be stored at least 18 inches off the ground. Controlling insect and rodent populations in the area also will help to discourage snakes by eliminating their food supply. Recipe is on the box of crystals sold wherever feeders are for sale. Since most of the damage armadillos cause is a result of their digging for insects and other invertebrates in the soil, an insecticide can be used to make the area less attractive to armadillos.
Live trapping is also an effective way to capture armadillos.
Traps should be placed in trails near fences or beside buildings. Over-ripe or spoiled fruit, earthworms or fishing worms are good baits. Place chicken wire over area where bulbs are planted until sprouts come up. There is no practical solution. I want to plant some tomatoes, hot peppers, and bell peppers in my backyard.
