I don’t leave food out. Garbage gets tossed, counters are cleaned. I replaced half the windows in my home and caulked up the rest. I bought a salt gun and have been picking them off but there’s always more.
How do I figure out where these little fuckers are getting in?
Some places use a directed air blast at the door whenever it opens up. Enough to push any bugs away from opening the door.
Air curtains.
In a residential home?
Bugs are pretty weak compared to humans so it makes sense that all it takes to keep a bug from opening the door is an air blast.
