LOW HARM DESIGN
Thorny Devils are DESIGNED to minimize harm while providing a very effective and low cost intruder deterrent. See videos example “Low Harm”

LOW VISUAL IMPACT
Although they can readily be seen up close, the low spike profile and neutral color blends readily with existing structures, fences etc., avoiding the ugliness of most other security products. Their pointy appearance combined with the prickly feel of the thorns, deters instantly, so intruders are warned (three ways) before attempting to climb (i.e. by sight, warning signs and touch).

COMMON SENSE
Thorny Devils Fence Capping modifies behavior, because intruders need to act against their own natural instincts in order to climb onto the thorns. Easily seen and easily avoided. Our thorns are made with blunted tips, as a safeguard against foolishness, and to protect pets.

Thorny Devils Fence Capping is made from RECYCLABLE plastics.

WARNING SIGNS Highlight the product is in use, and therefore educate passers-by as well as potential climbers, adding to the overall deterrent effect and safety of the property.

REDUCING DISEASE & NOISE
Stray and wandering cats often use children’s play areas (e.g. sand pit) for a toilet with many recorded cases of children suffering serious animal borne sickness e.g. the toxoplasmosis parasite.
Possums & cats urinate and defecate throughout their domains and frequently use fence tops as a highway disturbing the neighborhood peace by upsetting dogs.

AVOIDING PROPERTY DAMAGE
As well as vandals, some animals such as possums are prolific urban survivors notorious for helping themselves to flowers, fruit, trees, vegetable gardens and rubbish tins. They often cause damage to buildings and amenities, nesting in roof spaces and defecating on/from roof tops when visiting nesting or feeding sites.

PROTECTING WILDLIFE & PETS
Pets and feral animals are a threat to wildlife. Stalking is fundamental nature. Thorny Devils provide an uncomfortable barrier for some animals and pets. Importantly, for pet lovers, animals are protected by their own keen eyesight, quick reflexes, natural wariness and their smallish size (which means they do not generally exert enough pressure to be harmed).

News & Feedback

  • 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.
    D) Cats and possums have very keen eyesight and excellent survival skills. They easily recognize the Thorny Devil spikes from a distance; and once they have encountered them, they generally choose to modify their behaviour.
    E) Thorny Devils are low harm, obvious and benign.
