    Life in the summertime is often full of pests. Like most Long Island homeowners, I want to ensure my suburban life with pest-free living. So it was with wide-eyed wonder that I greeted the smiling exterminator (灭虫者) who rang my bell.

“We’ll be serving your neighbors, Mike and Sarah (I’m not familiar with either one by name),” he waved in the other direction. “Since we’ll have a team here tomorrow, we’re offering a discount.” He came out with numbers beginning from $299 then in seconds to $89.

“You’ve probably been seeing the ant hills around.” he moved toward my front walkway and lawn. “And have you seen the bees that dig nests in the ground?” he continued with his head shaking up and down pushing me to do the same.

“What we do is spray three feet out from your foundation and three feet up.” As he was talking, and without breaking eye contact, he opened his iPad cover and began operating at the screen to show me frightening images. “It also kills other pests, like spiders. It is the best pesticide (杀虫剂),” he said, pausing for effect.

He then went into soft talk to close the deal, correctly foreseeing that I would be concerned about safety and the environmental impact on my vegetable garden, plants and our little patch of planet here on Long Island. “The products are environmentally responsible, safe with children and pets,” he said.

I’m unkind when it comes to unwanted visitors entering on my out-of-doors moments. Any insect found in my house or on my deck is bound to be poisoned or pancaked.

Unfortunately for the exterminator, just as I was considering making an appointment, Billy, my fearless husband, pulled into our driveway, which made me ask for a business card out of politeness instead.
