What Do Bed Bugs Look Like?

Bedbugs are typically small and flat in shape, with a reddish-brown to mahogany color. Their bodies are oval-shaped and measure about 4-5 millimeters in length, roughly the size of an apple seed. When unfed, they appear flattened, but after feeding, they become more elongated and engorged.

Bedbugs have specialized mouthparts that are adapted for piercing skin and sucking blood. They possess a beak-like structure called a proboscis, which they use to pierce the skin and extract blood during feeding.

  • Egg → First Nymph Instar → Second Nymph Instar → Third Nymph Instar → Fourth Nymph Instar → Fifth Nymph Instar → Adult Bed Bug

Bed bugs require a blood meal to molt and progress through each nymphal stage. The entire life cycle from egg to adult typically takes about 5-8 weeks, but this duration can vary based on factors like temperature, humidity, and food availability. Warm temperatures and ample food can accelerate the bed bug life cycle.

It’s important to note that bed bugs can reproduce rapidly, making it critical to address infestations promptly and thoroughly to prevent a growing population and a more challenging infestation to manage. Professional pest control services are often necessary for effective bed bug elimination.


Where Can Bed Bugs Live?

Bedbugs are attracted to warmth, carbon dioxide, and specific chemicals emitted by their hosts. They are highly adaptable pests that can live in various environments as long as they have access to a blood meal.
