Every claim, mapped to its origin

Bed bug pyrethroid resistance is now globally documented; management has shifted toward heat treatment, IPM and resistance-management combinations.

Synthesis of 64 case reports / 85 patients: pruritic erythematous maculopapules in clusters or linear/curvilinear distribution in exposed body areas. Repeated bites may cause sensitization with vesicles, urticarial wheals, bullae or systemic hypersensitivity. Local trauma can lead to secondary bacterial infection (ecthyma, cellulitis, lymphangitis).

The global resurgence of bed bugs over the past two decades is believed to be primarily due to the development of insecticide resistance, along with global travel and poor pest management.

Diatomaceous earth: 90% bed bug mortality after 10 days. Hot Shot bed bug spray: 12% (same as water control). Pyrethroid-based foggers: no effect on field strain.

In 14 of 17 Berlin field strains, pyrosequencing revealed the L925I substitution at allele frequencies 30-100%. One strain additionally V419L (40% males / 96% females). 5 of 7 strains showed elevated CYP397A1 mRNA (7.1 to 56-fold).

University of Kentucky survey on whether US travelers actually inspect hotel rooms for bed bugs. Supports the 'most travelers skip the 5-minute check' claim.

Of 20 studies analyzed: 70% reported bed bugs can harbor pathogens, but only 25% demonstrated experimental transmission to animals or humans, and none to humans naturally.

Wang and Kwan's heat-treatment study showing that a short, hot exposure of a packed suitcase reliably kills bed bugs at all life stages. The scientific basis for travel heat boxes.

Bed bugs disperse within and between apartments, but inter-unit movement is limited to short distances (adjacent units, same floor).

Field accuracy: mean detection rate 50% (15-77%), mean false-positive rate 32% (14-57%). 28 false positives across 11 teams; only 1 confirmed in 12-month follow-up. Handlers self-reported ≥95% accuracy.

Achieving 100% mortality requires a minimum exposure time of 80 hours at -16°C for all life stages including eggs. Mean supercooling point ranges -21.3 to -30.3°C; LLT99 -31.2°C.

Over 40 pathogens have been detected in bed bugs; no published study has demonstrated a causal relationship between bed bugs and infectious disease transmission to humans.

100% mortality of all life stages including eggs achieved at both 50°C and 55°C under commercial heat treatment conditions.

Mean adult survival time during starvation: 41.5 to 142.6 days. First instars 13.8-36.3 days. Resistance to insecticides shortens starvation survival.

ClimbUp passive interceptors detected bed bugs more effectively than visual inspection in low-level infestations; over 7 days trapped similar numbers as dry-ice trap in 1 day.

60°C wash on 30-min cycle achieves 100% mortality of all life stages. 30 min HOT dryer cycle achieves 100% mortality alone. 10-min HOT only 75-85%. 40°C wash kills adults/nymphs but only 25% of eggs.

100% adult mortality at 41°C / 100 min or 43°C / 25 min. Adult LTime99 at 45°C = 94.8 min; eggs survived 7 h at 45°C and 71.5 min at 48°C.

No bite morphology or distribution pattern reliably distinguishes bed bug bites from other arthropod bites. Repeated infestation can cause PTSD-like symptoms.

Lab trials: 97.5% positive indication rate at detecting live bed bugs with 0% false positives. Discrimination from dead bugs/cast skins/feces: 95% true positive, 3% false positive.

Bed bugs hatch after 6 to 10 days at room temperature; saliva contains anti-coagulant nitrophorin and apyrase causing delayed bite reactions.
