Bed Bug Bites on Suu's Arm showing bite pattern
1

Vee was terrified after repeatedly being bitten by bed bugs.

2

There are two bites here; if just one bug is biting, the pattern of bites will be close together but if you have multiple bed bugs biting, the pattern may be spread out.

3

She found that her arm was near the location of the bed bug’s nest.

4

She didn’t feel any of these bites because the bed bug injected its saliva to numb the area bitten.

These bites had been occurring for a long time before she found the nest and eliminated them herself.

Often, bed bug bites look like a line made up of red dots as shown above. From the time the bug sticks its mouthpart into you and begins feeding, to the time its done, is only about 15 minutes, and for a nymph, it’s less.

There are two sections to the mouthpart, one is used to inject a mixture of anticoagulant and anesthetic, while the other is used to suck up your blood. There could be multiple bugs biting your body and you would never notice until you wake up and discover yourself covered in red bumps!

The pictures above are great examples of what the bed bug bites look like! This bug often bites in a line as it moves along your skin while feeding; notice the red bite marks that form a pattern on Monica’s side and also the seven bite marks in the picture of her hand?

Just because you where bitten seven times does not mean you have more than one adult bug – because they move around while feeding, it’s possible that only one could have caused all that irritation!

If the bites are from nymphs of a new nest, you may have multiple smaller bumps, as in the picture above showing Richard’s arm covered with bites. In fact, his whole body was viciously attacked while sleeping and his arm alone had more than 50 bites! His thigh, calf, legs, back, and face had multiple bites.

Adam’s bites were from a new infestation only 30 days old. Obviously, the nymphs were ready for their first feeding. The grouping of bites are circled in black.

Here is what bed bug bites look like on legs, arms, back skin, children, and other parts of the human body.
