Types of Bed Bugs

There are several species of bed bugs, among them two most common ones that attacket humans are:

A. Common Bed Bug (Cimex lectularius)

  • It found in worldwide but mostly found in temperate regions..
  • Normally like to feed human blood , it can also feed on animals..
  • It like to live in homes, hotels, and public spaces.

B. Tropical Bed Bug (Cimex hemipterus)

  • Mostly live in tropical and subtropical regions..
  • They have similar feeding habits to the common bed bug but it like to leave in warmer climates.

C. Related Species (Less Common in Hominid Habitats

  • Bat Bugs (Cimex pilosellus, Cimex adjunctus, Cimex pipistrelli) — Present in bats’ nests but bite humans.

  • Swallow Bugs (Oeciacus vicarius) – Located in bird nests and can become a nuisance to houses adjacent to bird flies.

  • Poultry Bugs (Haematosiphon inodorus) – Found in poultry farms and can bite humans.

Physical Features of Bed Bugs

  • Size: Adult bed bugs are 5-7 mm long (about the size of an apple seed).
  • Color: Reddish brown (infrequent digesting), bright red (after feeding).
  • Shape: Oval, flattened body (unfed); swollen and elongated body (after feeding)
  • Legs & Wings: 6 legs, 0 wings (Flightless but fast crawlers).
  • Antennae: Short, segmented antennae.

Life Cycle of Bed Bugs

Bed bugs undergo incomplete metamorphosis, which means they progress through three major stages:

A. Egg Stage

  • Bed bugs are known to lay eggs in dark places such as mattress seams, furniture crevices and cracks.
  • The eggs are 1 mm long, white, and hatch in 6-10 days.

B. Nymph Stage (5 Instars)

  • Nymphs look like smaller and translucent adult bed bugs.
  • To do this they must take a blood meal in order to molt and grow.
  • Nymphs develop over 5 instar stages to become adults.
  • That process takes 4-6 weeks, depending on the temperature and availability of food.

C. Adult Stage

  • Adults live for 6-12 months and can go several months without feeding.
  • One female lays 200-500 eggs during her lifetime.

Feeding Habits

  • Bed bugs are humans’ bloodsucking enemy, though they will bite pets and other animals if needs be.
  • They sense heat and carbon dioxide to find their hosts.
  • Feeding takes 3 to 10 minutes and then they retreat to their hiding places.
  • Bites are typically painless at first, but they become itchy, red and inflamed over time.

Common Hiding Places

Bed bugs excel at hiding in small cracks and crevices, such as:

  • Mattresses, box springs, and bed frames
  • Carpets and rugs
  • Sofas and cushions
  • Cracks in the wall or around electrical outlets
  • Luggage and clothing
  • And underneath wallpaper and picture frames

Signs of Bed Bug Infestation

  • Bite marks: Red, itchy bites that tend to form in a line or cluster on exposed skin.
  • Blood Spots: These are little red or brown dots that you may see on your sheets and pillowcases.
  • Fecal Spots: Dark, inky spots found on bedding, walls, or furniture.
  • Odour: Strong sweet, musty odour in heavy infestations
  • Shed Skins: Pale yellow exoskeletons molted by nymphs after they outgrew their old skins.

How Bed Bugs Spread

  • Travel: Hitch-hiking on baggage, garments and furniture.
  • Second Hand Items: Used furniture may harbor bed bugs that can infest the home.
  • Shared Walls: Can pass through walls in apartment buildings and hotels.
  • Public Place: It can be at buses, trains, cinemas, offices.

Health Risks of Bed Bugs

  • Dry skin: Scaly, itch welts due to allergic responses
  • Infections: Scratching too much may cause secondary infections of the skin.
  • Sleep Impairment: Anxiety/insomnia as a result of chronic bites.
  • Psychological Effects: Anxiety and paranoia in heavy infestations.

  • Steam Cleaner: Kill bedbugs and their eggs with steam (over 120° F or 50° C).
  • Sealing Cracks: Close gaps in walls, furniture and floors to eliminate hiding spots
  • Silica Gel or Diatomaceous Earth: Spread around hiding places to dry out and eliminate bedbugs.

B. Chemical Treatments

  • Insecticide Sprays: Use another kind of sprays (Pyrethroids, Neonicotinoids, Desiccants).
  • Bug Traps: Sticky traps can be used to test for and decrease populations of bed bugs.
  • Fumigation: If the infestation is large enough, professional fumigation may be the answer.

C. Professional Pest Control

  • Heat Treatment: heats whole-room to over 50°C (122°F) to kill all bed bugs and eggs.
  • Chemical Treatment: Use of strong professional pesticides for bad infestations.
  • Cryonite freezing: This method uses carbon dioxide to rapidly freeze bed bugs.
