• Eliminate sources of moisture or standing water.
• Keep tree branches and other plants cut back from the house.
• Keep kitchens clean by wiping counters and emptying the garbage frequently.
• Keep all food containers sealed.
• Avoid leaving pets' food dishes out for long periods of time.
• Keep trash containers clean and sealed, both indoors and outdoors.
• Screen windows and doors.
• If you see signs of pests or suspect infestation, contact a licensed pest professional.
