I am often asked if I will guarantee bed bug treatments, "No" is the answer. They are difficult to treat but can be eradicated as long as a thorough approach is taken.
My best advice is:
Treat all residual insecticides as if they are contact sprays, in reality the residual element is minimal and short lived.
Fogging applications only drive the bed bugs deeper into their harbourage. Also, it is difficult for it to penetrate deep into tiny crevices where they may be hiding.
The best and most effective control in my experience comes from cooperation between the client and pest controller carrying out the treatment, the effectiveness of the treatment and management plan will ultimately depend on the level of consumer cooperation and this will ultimately determine the outcome.
Once a treatment has been carried out, if a re-treatment is required, you should wait for four weeks before retreating with a different formulation, alternating between a pyrethroid and carbonate insecticide formulation.
You should seek specialist advice if you think that you have bed bugs and call in a professional like Pest Purge as soon as any signs are spotted.
