Bed bugs are small insects that are about the size and shape of an apple seed. They are flat and oval-shaped, with a reddish-brown coloration. Adult bed bugs typically measure between 4 to 5 millimeters in length and 2 to 3 millimeters in width, which is roughly the size of a lentil.
Bed bug eggs are even smaller, measuring about 1 millimeter in length, which is about the size of a pinhead. Newly hatched bed bugs, or nymphs, are also very small, typically measuring about 1.5 millimeters in length. However, they grow rapidly and can reach adulthood within just a few months.
Despite their small size, bed bugs can cause a great deal of discomfort and distress to those they infest. They feed on the blood of humans and animals, leaving behind itchy and irritating bites. Due to their small size, bed bugs can also be difficult to detect and eliminate, making them challenging pests to deal with. It's important to take steps to prevent bed bug infestations and to seek professional treatment if you suspect that you have an infestation.
