For questions about controlling garden pests
Garden pests can include insects, other invertebrates, mammals, birds, and domesticated creatures. Although "pest" indicates that they actively destroy plants and crops, this tag can also be used for domestic animals (cats/dogs) that merely cause inconveniences (see example question).
A range of control methods are available including synthetic chemicals, organic controls, traps, and deterrents. Clearly not all methods are appropriate for all pests or situations, and many methods are illegal for specific pests and jurisdictions.
