Fighting insects in your kitchen is different from the rest of your home because it's where your food is, not to mention your eating utensils and dishes. You don't exactly want to set off a flea bomb on your kitchen counter. For this reason, prevention is the main ingredient to keeping a pest-free kitchen. Keep trash in the can and emptied often. Clean up any liquid or food spills immediately. Take care to prevent any kind of long-term food spoilage from happening. One soggy orange at the bottom of your fruit bowl ruin an otherwise clean scene. Some insect traps under the cabinets are also a good idea.
