Hunting decoys are the early predecessors of garden owls. Both Native Americans and Europeans used bird decoys in strategic hunting practices. [15] [16] European records show efforts to reducing bird damage to crops though usage of decoys dating back to the 1400s. Books on pest control that mention using decoys were written in the 1600s.

Cats in Australia have been found to have European origins. [30] This is important to note because of their effect on native species. Feral cats in Australia have been linked to the decline and extinction of various native animals. They have been shown to cause a significant impact on ground nesting birds and small native mammals.

This makes the barn owl one of the most economically valuable wildlife animals for agriculture. Farmers often find these owls more effective than poison in keeping down rodent pests, and they can encourage barn owl habitation by providing nesting sites. [27]
In addition, biological pest control sometimes makes use of plant defenses to reduce crop damage by herbivores. Techniques include polyculture, the planting together of two or more species such as a primary crop and a secondary plant, which may also be a crop. This can allow the secondary plant's defensive chemicals to protect the crop planted ...
Some reptiles, such as the sand lizard of Europe, have eyespots; in the sand lizard's case, there is a row of spots along the back, and a row on each side. [12]Many species of cat, including Geoffroy's cats, jungle cats, pampas cats, and servals, have white markings, whether spots or bars, on the backs of their ears; it is possible that these signal "follow me" to the young of the species.
Pellets from a long-eared owl. The alimentary canal of a bird. Long-eared owl pellets and rodent bones obtained from dissected pellets (1 bar = 1 cm). A pellet, in ornithology, is the mass of undigested parts of a bird's food that some bird species occasionally regurgitate.
All species of owl in the European and northern Asian regions hunt rodents, as does the eagle-owl, and in many the very same microtine rodents such as voles and lemmings will be favored. [ 106 ] [ 128 ] [ 129 ] Even the 58.5 g (2.06 oz) Eurasian pygmy owl ( Glaucidium passerinum ), at a whooping one-fortieth of the weight of an eagle-owl, will ...
A trap crop is used for attracting the insect and pests away from a target crop field. Many trap crops have successfully diverted pests from focal crops in small scale greenhouse, garden and field experiments; [1] a small portion of these plants have been shown to reduce pest damage at larger commercial scales.
