Pesticides can ensure that a pest is removed, and that plants and gardens are protected. The EU and the UK have the strictest rules worldwide when it comes to pesticides, meaning the most damaging pesticides are not found in the UK. Despite this, however, there are concerns about chemical leaks into the environment which kill and impact organisms. There are also issues in which synthetic pesticides can attack other, unintended organisms, impacting the wildlife in and near gardens. Organic pesticides are an alternate to synthetic pesticides (more information can be found below) which have less of an impact on the environment and help to ensure local environmental sustainability.
– There are guides which specify how to repel certain pests from the garden. These guides advocate alternates which re not chemical in origin, they range from planting varieties of plants to using materials to repel pests. (ref)
