Crickets Inside House

I purchased a gallon of 9 month insect repellent spray from the hardware store and sprayed my foundation and all around the basement windows with this stuff. No more spiders or crickets except for the occasional one here & there. I live in a fairly dry climate so spraying twice a year is good for me but give it a try. For the crickets already in your house, there is a granular bait you can use for them to feed on to kill them.
