Why are Bed Bugs spreading so rapidly?

  •          Phenomenal explosion in major metropolitan regions 
  •     Increase in travel, loss of pesticidal tools & changes in how the industry operates
  •      Multi family housing & where they’re from
  •      Cruise ships
  •      Bed Bugs are master hitch hikers & hard to detect in low numbers 
  •      Public generally does not know what bed bugs are, how to avoid them, how to recognize a problem 
  •      Most modern insecticides are not effective

  •      Nocturnal - normally move & feed at night
  •      Don’t jump or fly – move into suitcases at night – can move fairly fast
  •      Very mobile and can travel between apartments and dorms
  •      20% of apartments could be infested & not aware of problem
  •      Move into other units above, beside & behind location of initial infestation
  •      People that are bitten don’t always have a reaction
  •      Bed bugs will make bites in a line along person’s skin
  •      Not vectors – not know to carry diseases

  •      Services offered, abilities, experience, staffing
  •      Control options
  •      Conventional insecticide treatment (2-4 follow-up visits on average)
  •      Steam – very time consuming
  •      Freezing “cryonite units”, chest freezers (1 week minimum)
  •      Fumigation – no residual chemical afterwards
  •      “Thermal Remediation” Heat to 120°F for 5 hours (clothes dryer will kill bed bugs – 30 minutes on hot cycle)
  •      Nuvan Prostrips – DDP – Alternative to fumigation – not approved in living spaces
  •      Health Department Complaint Calls – schools, medical offices, nursing homes, lodging facilities, homeless shelters, etc.
