We typically (tho not to frequently) get guys who want to do tree work for us or pest control guys. They all ring the bell, then step back off the porch to the foot of the steps.
The pest control guys (2 in 2 days) are really “assertive” - asking if I’ve talked to “your neighbor, Dave.” Um, no. Other than the guy directly next door, we don’t know anyone’s names. We’ll wave and/or say hi to anyone walking by, but the houses are spread out on large lots and people tend to stay inside unless mowing. So, back to the topic, no, I don’t discuss pests with “Dave” or anyone else. At that point, I just say “Thanks, but not interested” and I go back inside, even if the sales guy is still talking.
The tree guys are less annoying, and in the past, we have hired a couple of them. In fact, the next one who stops by may well get a job.
