Cave bugs are monsters that require level 7 Slayer to kill. They are found in the Lumbridge Swamp Caves, and stronger variants can be located in the Dorgesh-Kaan South Dungeon. They are a good source of low level herbs, which can aid beginning players in training Herblore.

Significantly more powerful Cave bugs, with a combat level of 96, can be found in the Dorgesh-Kaan South Dungeon, located south of the city of Dorgesh-Kaan, but can only be accessed after the completion of the Death to the Dorgeshuun quest.

A light source is required for these dungeons, along with a rope to place down on the hole leading to the Lumbridge Swamp Caves, if it has not been done so previously.

Players should be on the lookout for Wall beasts within the Lumbridge Swamp Caves, which are monsters that will grab and attack you, if you are in their line of sight. To avoid being hit, either stand one square directly beside a hole in the wall and run across to the other side, or have a spiny helmet equipped.

Defeating a Cave bug in the Lumbridge Swamp Caves is a requirement for the easy Lumbridge & Draynor Diary tasks.
