Bed bug morphology

Adult bed bugs measure around 3 to 7 mm in length, are oval and flattened in shape, and have a reddish-brown color after taking a blood meal. Their body is divided into three parts: head, thorax and abdomen. They have segmented antennae, compound eyes and stinging, sucking mouthparts. Nymphs, or young bugs, are smaller and almost transparent before feeding.

Biology and Life Cycle

Bed bugs go through three stages of development: egg, nymph and adult. They moult after each blood meal. Eggs are laid 3 to 10 days after mating. 3 to 5 eggs are laid daily by one female. Females are fertile for around 2 months. A female can lay between 200 and 500 eggs in her lifetime, which favors rapid infestation if left unchecked. Ambient temperature is also a crucial factor. The incubation period of eggs decreases as ambient temperature rises. At 28°C, an egg incubates in 4 days, compared with 50 days at 13°C.

Bed bug detection

Early detection is essential to avoid a major infestation. Here are some warning signs of bed bugs:

• Observation of stings: Stings often appear in lines or groups on exposed skin.
• Observation of bloodstains: Small bloodstains on sheets or mattresses.
• Observation of excrement: Small black or brown spots on sheets, mattresses and furniture.
• Eggs and moults: Transparent eggshells and moults found in caches.
• Specimen observation: Bed bugs tend to hide in seams, folds, mattress buttons, bedside cabinets, junctions and baseboards, in cracks, door frames, etc.
• Detection methods: to detect signs of bed bugs as quickly as possible, the following methods are recommended:
• Visual inspection by a qualified technician: a qualified technician can visually inspect at-risk areas to confirm/confirm the presence of bed bugs.
• Detection traps: equipped with adhesive tape or carbon dioxide generator. Limited to predetermined, restricted areas around the bed.
• Trained detection dogs: thanks to their sense of smell, detection is much more effective than visual inspection by humans. However, reliability is never absolute.

Bed bug control methods

There are several methods for controlling bed bugs, ranging from chemical solutions to physical approaches. Here are the most common:

Physical methods

• Anti-fly equipment: waterproof mattress covers and footboard barriers
• Vacuuming: Use a powerful vacuum cleaner to remove bed bugs and eggs from mattresses, furniture and crevices.
• Washing: Wash contaminated clothing, bedding and other items at high temperature (at least 60°C).
• Freezing: place contaminated linen and objects at at least -20°C for a few days.
• Cryogenics: apply a blast of dry ice for a few seconds on infested areas.
• Heating: localized or volumetric heating of rooms and areas to be treated at temperatures between 60°C and 180°C.

Chemical treatments

• Insecticide spraying: containing a sufficiently high dose of a persistent active ingredient, in liquid or powder form, in the home and surrounding areas, as bed bugs can escape the insecticide.
• Volumetric insecticide fogging: only as a complement to spraying, to eliminate bedbugs at height, flush them out of their hiding places and move them around freshly sprayed surfaces.

Follow-up

Treatment, whether physical or chemical, is not instantaneous and miraculous. Eggs are resistant to insecticides. Follow-up visits and re-treatment are necessary.

1st follow-up visit: within 10 days of the first treatment, to check the results of the initial treatment and detect any new niches after the treatment has escaped. A second treatment is applied immediately as the eggs continue to hatch.

2nd follow-up visit: no later than the end of the 2nd month after the initial treatment. This period corresponds to the female's fertile period. The aim is to check that the infestation is over and that no new specimens have appeared.

3rd (4th, 5th, ...) follow-up visit: in cases where the previous visit shows that the infestation persists and has not been eradicated. Large-scale infestations may require up to five treatments.
