How do you keep rats from eating starch paste or wheat adhesive?

Answer 1

The key to keeping rodents out of starch paste or wheat adhesive is storing them in metal tins or the like and placing them in a clean storage area.

Different chemicals have been added to materials like the paste or adhesive to deter the nibbling of pests, but they are toxic. A toxic starch paste or wheat adhesive has extremely limited use. The best approach is to put products in a metal or thick plastic container or in a room that has been specially "shielded" to prevent rodents from entering. It is a challenge to construct a space that is properly sealed to keep rodents out, but securing the space or placing the product in containers that are generally "rodent proof" is the best approach.

Unless the Pied Piper is available, the pests generally cannot be eliminated. They can only be discouraged or deterred, and the ways to do that are long understood. They involve nothing high tech or any advanced science, but the simple application of common materials and a bit of thinking. Metal tins come in a variety of sizes and shapes, and the thick poly materials (like a common 5 gallon paint bucket with its snap-on lid) are also excellent for storing things out of the reach of the teeth of rodents. Simple, and easy.
