Claims10
A composition consisting essentially of a blend of:
- (i) a high strength poly(vinyl alcohol) hydrogel;
- (ii) water;
- (iii) at least one solid pest repellent, and,
- (iv) a water soluble, non-volatile, freezing point depressant for (ii) which does not solubilize (i), complex (i), or de-stabilize the composition;
- said freezing point depressant being selected from a group consisting of:
- (a) inorganic salts and
- (b) organic solids.
