Bedbugs – Symptoms and causes

Bedbugs: Understanding the Bites, Causes, and Signs of Infestation

Bedbugs are small, parasitic insects that feed on human blood. While not dangerous in the traditional sense, they can be a serious nuisance due to their bites and the psychological stress they can cause.

Symptoms of Bedbug Bites:

  • Red, itchy bumps, often in clusters or lines
  • Bites typically appear on exposed skin during sleep, such as arms, legs, shoulders, and face
  • Bites may not appear immediately, and some people may not have any reaction at all

It’s important to note:

  • Bedbug bites can be mistaken for bites from other insects, mosquito bites in particular.
  • The absence of bites doesn’t necessarily rule out a bedbug infestation.

Causes of Bedbug Infestations:

Bedbugs are not associated with poor hygiene. They are opportunistic feeders and can infest any location, including:

  • Homes and apartments
  • Hotels and motels
  • Shelters and dormitories
  • Public transportation

Bedbugs can travel easily and spread through:

  • Luggage and clothing
  • Used furniture
  • Pets

Signs of a Bedbug Infestation:

  • Live bedbugs: These are reddish-brown, flat oval insects about the size of an apple seed. They are most active at night and can hide in cracks and crevices.
  • Bedbug casings: These are the shed skins of bedbugs and appear as translucent brown shells.
  • Bedbug excrement: These are small, dark brown or reddish spots, often found on mattresses, bedding, or furniture.
  • A sweet, musty odor: This is not present in all infestations, but some people report a distinctive odor associated with bedbugs.

If you suspect a bedbug infestation, it’s crucial to take action immediately:

  • Contact a licensed pest control professional for proper inspection and treatment.
  • Wash all bedding and clothes in hot water (at least 130°F or 54°C) and dry them on high heat.
  • Vacuum carpets and furniture thoroughly, paying close attention to seams and edges.
  • Seal cracks and crevices in walls and furniture to prevent bedbugs from hiding.
  • Encase mattresses and box springs in special covers to trap and kill any remaining bedbugs.


  • Bedbug infestations can be challenging to eliminate, and professional help is essential for effective eradication.
  • Early detection and intervention are crucial to prevent the problem from worsening.
  • Following the recommendations of a pest control professional is crucial for successful treatment.
