Never use these products on food, edible plants, or directly on fruit or nuts of trees. Other Measures For serious problems with pigeons, gulls and other birds roosting on, or in, buildings, consult a licensed pest control service to employ an integrated pest management program for problem birds. Cats and Dogs Damage Cats use dry soil under shrubs, cultivated garden soil, and children's sand boxes as litter boxes. Cat feces are a health hazard as they are the source of toxiplasmosis infections in people. Dog urine damages plants.
Feces are unattractive and unsanitary on lawns and garden areas.
This method is particularly effective on cats. Cover freshly cultivated soil and bare soil areas under shrubs with bird netting, chicken wire, or commercially designed cat mats to keep cats from digging. These are not for use on edible plants. Place wire fencing around trees and shrubs to prevent urine from reaching trunks and roots. Deer Damage Deer browse succulent plant growth including flower heads, tender new leaves, and the shoots of many types of plants.
