  Abstract  
  New bed bug control products, methods and Codes of Practices have been introduced, but it is likely that until we have a novel insecticide molecule and their formulations to which the bed bugs are fully susceptible, we cannot achieve appropriate results. Following a series of individual laboratory trials, the authors have designed a novel semi-field laboratory trial method. The work introduces this new technique, and describes the benefits, results and conclusions. Presented are the short and long-term effects of combinations of S-methoprene insect growth regulator, natural pyrethrum and synergist. According to the tests performed, the combinations are active against pyrethroids- and carbamate-resistant bed bug strains, with the S-methoprene insect growth regulator interrupting the bed bug’s development and reproduction.
