Greens Environmental Pest Services recommend the building design be appropriate for food production.
The design and construction of the food premises should
1.not permit the entry of Pests
2. not provide harbourage for Pests
3. not attract or encourage pests
Not permit the entry of pests - pest prevention
Elimination of food sources for the pests is a standard component of IPM. Not only does this discourage the increase of pest populations but also it will increase the success of baiting programs where these are used.
A high level of cleanliness is a necessary start. Not only does lack of cleanliness afford food sources for pests, it can lead to poor hygiene and increases odours attractive to pests and the risk of bacteria and other food contaminants.
