how to keep crickets from coming into my home?
Answers:
I get earwigs in my house and I use Spectracide Insect Killer to spray around the foundation of my house. I usually spray in the Spring and mid-Summer and I don't get those or any other bugs coming in.

You could try to get a bunch of frogs to hang out around your house entrances...
Don't answer the door. Sheesh!
They must be getting in through a gap somewhere, check around and get some expanding foam filler from your local hardware store and fill in any gaps or holes you see (make sure to follow the direcetions on the can). If it's messy or overflowing out of the gap, you can take a razor blade or a small file and shim off the excess when it's dry. It can also be painted to match the surroundings (and some foams come in different colours). Hope this helps!
You may have a nest in yard. I would visit a garden center and find poison to dilute and spray the whole yard and find the nest if there is one.
