    Crickets can enter your home through cracks or gaps around the house. If there is a lot of clutter inside, they can find a place to hide. If there are cardboard boxes, they can chew on them. Paper fibers are a source of sugar and food for them. When the boxes become damp micro fungi grow on them. Crickets are attracted to them and consume them. If your house has this sort of environment, crickets may find it a suitable place to live.

    You can seal the cracks through which the crickets enter the house. If there are crickets in the house, you can use sticky traps to capture them. You can also use some insecticides. But those insecticides may kill some beneficial insects also. So it is better to keep the house clean and run a dehumidifier to dry out the air. It will create an environment that is not suitable for them.
  • Question
    Can we change the beer can to something else like a Coke can?
    Community Answer
    Yes, the cricket should be attracted to the sugar in a soda can as well.
  • Question
    How can I tell if a cricket is in my home or outside?
    Community Answer
    Try going outside to see if the chirping is louder. If the chirping sounds louder when you're indoors, the cricket is probably in your house.
  • Question
    Can I mix sugar instead of using beer to kill a cricket?

  • Question
    Do crickets move around inside?
    Community Answer

  • Question
    Is there a possibility that it would also attract ants?
    Community Answer
    If you use the beer can method or the molasses method, there is a possibility that you could attract ants.
  • Question
    How do I catch crickets when they know where the traps are?
    Community Answer
    They aren't that smart. Amazon has a 36 pack of sticky traps for $14, and that is enough to cover 1,500 sq. ft.
  • Question
    Are glass bottles usable in place of a metal can?
    Community Answer
    They would have too easy a time getting out of the bottle. If it’s all you have, then try making a funnel with paper and tape, with the smaller opening being about 1/2” diameter, and taping it with the smaller end into the bottle.
  • Question
    What can you do if you're hearing them (crickets) in the walls all over the house?
    Community Answer
    If you can't see them much less catch them, it is probably best to call pest control.
  • Question
    Can I use corn syrup instead of molasses?
    Community Answer
    Yes, corn syrup will be sticky enough––maybe add some sugar though. Crickets are attracted to sugar.
  • Question
    Do crickets like everything that's sweet?
    Community Answer
    Yes, because anything sweet has sugar and crickets are attracted to sugar. Make sure to keep the sugar contained in a trap, you want to catch them, not attract them.
