Surface sprays are liquid solutions designed to kill or repel pests on various surfaces. They are commonly used in homes, gardens, and commercial spaces to manage insects like cockroaches, ants, and flies. These sprays can be applied directly to surfaces such as countertops, floors, and outdoor areas to create a barrier against pests. Most surface sprays contain active ingredients that target the nervous systems of insects, leading to their elimination. Users should follow the instructions on the label for safe and effective application, ensuring proper ventilation and avoiding contact with food or pets during use.
