In the US, many stores with food (grocery stores, restaurants) have what’s essentially a crappy pressurized airlock. You go through one set of doors, above which is an outward-facing blower, into a small room with higher pressure, then through another set of doors. The airlock is also often filled with hidden bug zappers, but even without them, insects getting in would be drastically reduced.

Well yeah that works I guess, impossible to fit into old and often small buildings though so not an option for us. Let alone at home!
Thx for the response!
For older and smaller buildings with food, we often have an “air curtain” generated by a blower above the door. https://berner.com/air-curtains-101/types-of-air-curtains/
Though I’ve never seen a home with one.
