R: Restriction is about making life as difficult as possible for any pests that do gain access to the premises by eliminating breeding harbourages.
Fumigation techniques typically only kill 90–99% of infestation Many fogging agents and pheromone disruption products fail to kill eggs, buried larvae or pupae. The high levels of gas concentration required to kill insect eggs creates a large diffusion gradient which leads to increased rate of gas loss to atmosphere or adjacent areas, resulting in an incomplete treatment. Only extremes of heat, cold, fumigation and radiation can kill 100% of all life stages of insect infestations, and only a well thought out integrated pest management programme can create the conditions that allow these measures to succeed and ensure proactive measures are taken to eliminate or reduce as far as possible the risks of re-infestation.
