There are several insects that eat bed bugs, but most of them are not safe or desirable to have in your home. Some of the insects that eat bed bugs include:

• Cockroaches: Cockroaches are omnivores and will eat anything they come across, including bed bugs and their eggs.

• Ants: Some species of ants, such as pharaoh ants, are known to feed on bed bugs.

• Spiders: Some species of spiders, such as Thanatus Flavidus and the Masked Hunter Bug, are known to eat bed bugs.

• Centipedes: House centipedes are known to feed on bed bugs.

• Mites: Dermatophagoides pteronyssinus, also known as mites, are known to feed on bed bugs.

It is important to note that while these insects may eat bed bugs, they are not a reliable form of natural population control. Insects typically only feed on bed bugs when the bed bug population is very large, and introducing other insects into your home can cause more problems than it solves. Additionally, there are no real "natural predators" that habitually prey on bed bugs or have evolved to eat them as their primary source of food.
