Bed bugs are small, wingless insects that feed on the blood of humans and animals. They are a common pest in homes and can be difficult to get rid of. Lizards are reptiles that are often found in homes, and they are known to eat a variety of insects, including bed bugs.
There is some evidence that suggests that lizards can help to control bed bug populations. One study found that lizards were able to consume up to 50 bed bugs per day. This suggests that lizards could be a potential biological control agent for bed bugs.
