Resistance by bedbugs to existing pesticides is already becoming apparent. In addition, they do not have communal nests and have shown limited response to available baits. This means that contact with conventional pesticides can be very limited. In addition, recolonisation following even successful clearance efforts is both rapid and difficult to avoid.

A biological agent able to multiply and spread within the infested environment would have a significant advantage. In addition, the demonstrated ability of biological agents to persist in the environment and to produce long-term control would be advantageous. Perception of this as a “green”, environmentally friendly option would also aid uptake, especially if supported by organic certification. Public revulsion will also support sales of such a product (see above).
Given the social pressures to avoid biting insect infestations, it is anticipated that an effective biological control could find ready use both in domestic and in commercial settings, replacing and supplementing chemical agents which are of limited efficacy. There is a high level of concern regarding the transfer of bedbugs from hotels to the home environment, so alongside domestic use the potential for use by hotels of an environmentally friendly bedbug control could be very significant.
