As pests generally like to feed on scraps of leftover food, be sure to clean up all spilled foods and clear the garbage regularly, putting them out properly in sealed bags or bins. Make sure that your home is kept clean, especially the kitchen area, and store all foods in sealed containers.
When using poisons or insecticides, always follow the manufacturer’s instructions and keep them out of the reach of children and pets. If the infestation is serious, call a pest control company as they have specialised knowledge and equipment to deal with various types of pests.
