Patio Pests: Is Your Outdoor Dining Area at Risk?

By Hope Bowman, Technical Specialist, Western Pest Services

Spring is in the air, which means patio season is about to commence for many restaurants and country clubs in the Metro New York area. Patio season means increased dining space – and hopefully diners, but without the right precautions, patios can also increase exposure to unwanted pests.

Outside, there are fewer barriers to block out pests, which means easier access to the food and water sources pests are attracted to. A few dropped crumbs and a spilled soda are the perfect meal for a number of pests. And, once they are drawn to your patio, there is a greater chance they’ll be drawn inside your establishment, too.

They are capable of carrying a number of disease-producing bacteria on their bodies, which can cause illnesses such as diarrhea, food poisoning, and pneumonia. To help keep crawling pests from finding a meal on your patio, follow these tips:
