Why do crickets from outside die when they are in my house?

If you are having a high traffic turn over of crickets, it just may be some have naturally lived out their lives. You see the new ones and then see and clean up the dead ones. You wont see all that are in the house at the same time. If you have put out insecticides for termites, spiders, pill bugs, cockroaches etc.,if your crickets make contact, by stepping in it or breathing it eating etc., they as insects will also die. They may be dying of hunger or thirst. Provide food and water to slow down their illness and death. If you are so tidy they have nothing to eat it's your fault they're dying. A little levity? They like greens and vegetalbes. Leave a little water on them and they'll love it. They will dine on some clothes that are made from plant products. I've always had a soft spot in my heart for them. Mom always said they were fairie's horses. Since the first time I saw Peter Pan with Tinkerbell, I made sure our crickets were safe. We never killed them. But then I remember "Uncle Remus's" story about the cricket in the Chimbley. Brer Bear got so mad at listening to it sing, he did every thing to kill it. The final straw was pouring hot water into the chimney holes. The chimney being made of sticks and mud, as was the standard of poor folks in those days, got soft and collapsed. Being midwinter, the bears suffered terribly. Ever after it's been know to be bad luck to harm or kill them. Go ahead annihilate them if you dare. I know, I just sit back and listen to them sing. I make sure there is always a little lettuce dampened with water Just as a little added insurance.

well clearly this a problem that can be prevented...don't let them in your house

Crickets are filthy living in their own feces. But they sing so people like them. Cockroaches on the other hand are very clean. They indicate dirty surroundings.
