Some parents use a similar solution on the thumbs of children who suck their thumbs more than they should. Denatonium benzoate is also used as an animal repellent. Products containing denatonium benzoate can be sprayed on trees, brushes, crops, and other material to prevent deer from grazing on those products. One of the product s first applications was as a treatment on pig s tails to prevent pigs from biting... 

Young children, particularly those below the age of 3, are also at risk from their habits - the tendency to put non-food objects in their mouths, and to suck their thumbs or fingers. Blood lead measures in children exposed to particular sources of lead have been demonstrated to peak at around 2-3 years of age (HMSO, 1983), and this peak is also evident, although less marked, in populations of children not exposed to specific sources of lead (Mahaffey et al, 1982).
