Every claim, mapped to its origin

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).

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

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.

[16:07] 'The spray aerosol and fogger bedbug killers all killed about 12% of the bedbugs after 10 days. And before you go all glass half full and think, well, 12% is better than nothing, our control, which was just water, also had a 12% mortality rate. So it's literally not better than nothing.' [16:33] 'There were some chemicals that on average were effective in killing about 50% if you sprayed the bedbugs directly. But if they were just hanging out in the area you sprayed later, it's once again the same as water.' [16:59] 'There was a superstar in our test, and that was the diatomaceous earth, with a nearly 90% mortality rate after 10 days.' [17:52] 'bedbugs die at 122 degrees Fahrenheit. Like, instantly. This is also 100% effective, and there's no way to build immunity to it.'

Abbar Cooper Ranabhat Pan Sked Wang 2022 JME: NJ prevalence study confirming that nearly half of bed bug infestations go unrecognized by residents (55.3% awareness) and that 78% of residents attempt self-treatment in the prior 6 months. One of the core US sources for multifamily-housing prevalence and resident behavior.

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).

Wang Singh Zha Cooper 2016 JME: combines prevalence (12.3% across 2,372 NJ apartments), symptom distribution (pain 90%, itch 20%, many asymptomatic), detection sensitivity (Climbup 89% vs visual 72%), and a low-cost building-wide protocol ($12/unit). Headline figure: 49% of detected infestations were in apartments whose residents had no idea.

Systematic review of bed bug pathogen carriage versus transmission: there is no causal relationship between bed bugs and infectious diseases in humans, and neutralizing factors in the bed bug body appear to limit pathogen viability.

Cooper Wang Singh 2016 JEE: two field experiments showing ClimbUp interceptors function as a standalone control measure for low-level infestations (not just as monitors). 50% of apartments eliminated by interceptors alone in 16 weeks; 96 to 100% across the intervention groups in 22 weeks.

Loudon 2016 Pest Management Science: experimental data on brief exterior heat treatment of luggage. Six minutes at 70-75°C kills all adult males on the surface. Bed bugs migrate into closed luggage at very low rates (3% in 24 h). Scientific basis for travel heat boxes, but explicitly limited to exterior treatment.

Pairs as the policy / review counterpart to the experimental Wang 2019 JIPM paper (28c540cf).

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

Phillips Aikins Thoms Demark Wang 2014 JEE: dose-response curves for sulfuryl fluoride (SF) fumigation against bed bug eggs, nymphs and adults at 25 and 15 degrees C, with specific field dosage recommendations. Used as structural fumigation (Vikane) in the US; not typical in Germany.

Eleven canine detection teams in naturally infested apartments. All handlers believed their dogs could detect infestations at a very high rate (>=95%). In three separate experiments, the mean (min, max) detection rate was 44 (10-100)% and mean false-positive rate was 15 (0-57)%. Four canine detection teams evaluated on multiple days were inconsistent in their ability to detect bed bugs and exhibited significant variance in accuracy between inspections on different days. Experiment I (controlled in-apartment setup): mean detection 50% (15-77%), mean false-positive 32% (14-57%).

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.

Bedbugs have become a serious pest in urban communities throughout the world. Non-chemical techniques and tools, and integrated pest management strategies are gaining popularity as they impose less environmental impact than pesticide driven programmes. This chapter discusses the use of 'low impact' tools and methods. Also, a community-wide programme for effective bedbug management in society is explained.

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.

Bed bug infestations can lead to a wide range of psychological effects, including nightmares, flashbacks, hypervigilance (to keep bed bugs away), insomnia, anxiety, avoidance behaviors, and personal dysfunction. Although the diagnostic criteria for PTSD have not been formally applied in this population, the symptoms suggest a posttraumatic stress reaction in a meaningful subset of patients.

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.

Bed bug bite reactions are uniphasic or multiphasic, similar to other insect bites and stings, and no morphology distinct from other arthropod bites has been described. The differential diagnosis includes other insect bites and mysterious skin rashes.

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.

All members of the family Cimicidae show traumatic insemination and a suite of female adaptations to this male trait. Bed bug saliva contains nitrophorin (a nitric-oxide-carrying hemoprotein, Valenzuela 1995) as the central vasodilatory component facilitating blood feeding.

Where do Bed Bugs Hide? Mattresses, box springs, bed frames and headboards (along seams and piping, under handles and labels). Under the thin dust cloth on bottom of box spring. Seams and fabric folds in curtains and under furniture, including chairs and sofas. Under wall-to-wall carpeting and padding. Anywhere there are cracks, crevices or nail holes in walls, and under wood moldings and baseboards. Under loose wallpaper and seams, and where ceiling and wall meet. In and behind picture frames and mirrors. Clothing and clutter stored in closets, under beds and elsewhere. Inside switch plates, electrical outlets, clocks, computers, phones, televisions and smoke detectors. On and in recently used luggage, backpacks and bags.
