You should call bed bug exterminators as soon as you suspect a bed bug infestation in your home. Common signs of bed bugs include:

1. Itchy Bites: Bed bug bites often appear as small, red, itchy bumps on the skin. They may be clustered together or appear in a line. However, it's important to note that not everyone reacts to bed bug bites, so the absence of bites does not necessarily mean you don't have bed bugs.
2. Bloodstains on Sheets or Mattresses: After feeding, bed bugs may leave behind small bloodstains on your bedding or mattress. These stains can appear reddish-brown and may be found where bed bugs have been crushed or where they have been feeding.
3. Fecal Spots: Bed bugs excrete digested blood after feeding, leaving behind dark, rusty-colored fecal spots on bedding, mattresses, or nearby furniture. These spots may resemble tiny dots or smears and are often found in clusters.
4. Shed Skins: As bed bugs grow and molt, they shed their exoskeletons. You may find these shed skins in areas where bed bugs hide, such as along mattress seams, bed frames, or behind furniture.
5. Musty Odor: In severe infestations, bed bugs can produce a musty odor described as sweet or sickly. This odor is often more noticeable in enclosed spaces or rooms with heavy infestations.
6. Visible Bed Bugs: In some cases, you may actually see live bed bugs. They are small, reddish-brown insects with flat bodies that swell and turn redder after feeding.

If you notice any of these signs, it's important to contact Bill Clark Pest Control immediately to promptly address the infestation and prevent it from spreading further.
