Bird Control Spike
A bird control spike, also known as an anti-roosting spike, pigeon spike, or roost modification, is a device consisting of long, needle-like rods used for bird control. Bird control spikes can be attached to building ledges, street lighting, and commercial signage to prevent wild or feral birds from perching or roosting. Birds can produce large quantities of unsightly and hygiene, unhygienic feces, and some birds have very loud bird song, calls that can be inconvenient for nearby residents, especially at night. As a result, bird control spikes are used to deter these birds without causing them harm or killing them. In an unexpected adaptation, some birds have collected the spikes and used them in their nests. Styles and usage Bird control deterrent spikes are normally around long, and work by reducing the area available for birds to land on. This forces larger varieties of birds, such as seagulls, pigeons, and crows, to land elsewhere. Birds that attempt to land on spike-protecte ...

Barbed Wire
Roll of modern agricultural barbed wire Barbed wire, also known as barb wire or bob wire (in the Southern and Southwestern United States), is a type of steel fencing wire constructed with sharp edges or points arranged at intervals along the strands. Its primary use is the construction of inexpensive fences, and it is also used as a security measure atop walls surrounding property. As a wire obstacle, it is a major feature of the fortifications in trench warfare. A person or animal trying to pass through or over barbed wire will suffer discomfort and possibly injury. Barbed wire fencing requires only fence posts, wire, and fixing devices such as staples. It is simple to construct and quick to erect, even by an unskilled person. The first patent in the United States for barbed wire was issued in 1867 to Lucien B. Smith of Kent, Ohio, who is regarded as the inventor. Joseph F. Glidden of DeKalb, Illinois, received a patent for the modern invention in 1874 after he made his o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Barbed Tape
Barbed tape or razor wire is a mesh of metal strips with sharp edges whose purpose is to prevent trespassing by humans or to secure facilities such as prisons where there is a risk of escape. The term "razor wire", through long usage, has generally been used to describe barbed tape products. Razor wire is much sharper than the standard barbed wire; it is named after its appearance but is not razor sharp. The points are very sharp and made to rip and snag clothing and flesh. The multiple blades of a razor-wire fence are designed to inflict serious cuts on anyone attempting to climb through or over it, which simultaneously gives it a strong psychological deterrence (psychology), deterrent effect. Although it can be circumvented relatively quickly by humans with tools (Bolt cutter, Bolt cutters being a prominent example). Attempting to get through razor wire without tools is incredibly hazardous and requires a substantial amount of time; thwarting such attempts or giving correspondi ...

Animal Repellent
An animal repellent consists of any object or method made with the intention of keeping animals away from personal items as well as food, plants or yourself. Plants and other living organisms naturally possess a special ability to emit chemicals known as semiochemicals as a way to defend themselves from predators. Humans purposely make use of some of those and create a way to repel animals through various forms of protection. Overview Repellents generally work by taking advantage of an animal's natural aversion to something, and often the thing chosen is something that the animal has learned to avoid (or instinctively avoids) in its natural environment. Chemical repellents fall into two main categories, odor and taste. The former work better in the warm season and the latter, which ward off an animal only after it eats, in the cold season. (For example, the smell of the lawn fertilizer Milorganite is claimed to make it an effective repellent.) Such repellents mimic natural s ...

The Department for Environment, Food and Rural Affairs (Defra) is a Departments of the Government of the United Kingdom, ministerial department of the government of the United Kingdom. It is responsible for environmental quality, environmental protection, food production and standards, agriculture, fisheries and rural communities in the entire United Kingdom. Memorandum of understanding, Concordats set out agreed frameworks for cooperation, between it and the Scottish Government, Welsh Government and Northern Ireland Executive, which have devolved responsibilities for these matters in their respective nations. Defra also leads for the United Kingdom on agricultural, fisheries and environmental matters in international negotiations on sustainable development and climate change, although a new Department of Energy and Climate Change was created on 3 October 2008 to take over the last responsibility; later transferred to the Department for Business, Energy and Industrial Strategy ...

Electric Fence
An electric fence is a barrier that uses electric shocks to deter humans and other animals from crossing a boundary. Most electric fences are used for agricultural purposes and other non-human animal control. They may also be used to protect high-security areas such as military installations or prisons, where potentially lethal voltages may be applied. Virtual electric fences for livestock using GPS technology have also been developed. Design and function Electric fences are designed to shock animals or humans if they attempt to cross the boundary. A component called a power energiser converts power into a brief high voltage pulse. One terminal of the power energiser releases an electrical pulse along a connected bare wire about once per second. Another terminal is connected to a metal rod implanted in the earth, called a ground or earth rod. An animal touching both the wire and the earth during a pulse will complete an electrical circuit and will conduct the pulse, causing ...

Snake
Snakes are elongated limbless reptiles of the suborder Serpentes (). Cladistically squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales much like other members of the group. Many species of snakes have skulls with several more joints than their lizard ancestors and relatives, enabling them to swallow prey much larger than their heads ( cranial kinesis). To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most only have one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have independently evolved elongate bodies without limbs or with greatly reduced limbs at least twenty-five times via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, althoug ...
