A "fly trap" is a device or tool that helps prevent flies and other flying insects from entering an area. Some common synonyms for "fly trap" include "insect trap," "fly catcher," "fly paper," "sticky trap," and "bug zapper." Insect traps often use a sticky substance, such as glue or honey, to attract and trap flies, while fly catchers can be made from materials such as plastic or fabric. Fly paper is a type of adhesive strip that traps insects upon contact, while bug zappers use electricity to kill flying insects. Regardless of the type of fly trap used, their purpose remains the same - to keep pesky flies at bay and create a more enjoyable environment.
