• Seal all unnecessary exterior openings - no matter how small - with weather resistant sealant or caulk. Many pests can fit through an opening as small as the width of a pencil
• Make sure all doors are tightly sealed to prevent pests from entering under closed doors. Remember to install or replace door sweeps if necessary
• Work with an HVAC professional to adjust the building’s airflow so that the air flows out when the door is opened, making it difficult for flying insects to enter the store
• Use sodium vapor lamps, instead of insect-attracting fluorescent lamps, in exterior light fixtures and fittings
• Using fluorescent lamps in car park lighting or other fixtures at least 100 feet from a building will pull flying insects away from the facility
• Examine the roof for signs of a bird infestation. Consider installing ledge treatments such as spikes to keep birds off the facility. Place netting or vinyl skirts around HVAC units to prevent birds from nesting underneath
