churchSpikesThorny Devil Spikes are used in homes, ranches, businesses, schools, parks, government facilities, airports, industrial facilities, food production plants, bridges, and roadways.

A. The thorns are short and their apex is purposely made with a radius.

B. Any painful effect can only be due to pressure applied to the thorns and as cats & possums only weigh a small amount, they are unable to exert harmful pressure.

C. The thorns are spaced to ensure that animals are made uncomfortable, yet not hurt.

Note: Material is PVC. Can be drilled, nailed or cut, painted and glued. It can be easily trimmed into strips or short saddles. Can be THERMO-FORMED to suit novel applications.
