A cricket constantly chirping in a hidden place in the home can be extremely annoying. But some people say "Don't kill crickets in the house -- it's bad luck!"
Crickets as Pets
In the Walt Disney film Mulan, Cri-kee the cricket is considered to be a lucky charm for Mulan's family. The idea was based on the traditional Chinese custom of keeping crickets in cages in the home for luck. Many Native American tribes also thought that crickets brought good luck, and the belief holds true for many Americans. Today, who believe that it is bad luck to kill a cricket in the house or harm a cricket at all.
Despite those beliefs, the incessant chirping of a cricket in one's home can quickly become annoying, especially when it only goes quiet when the search for it begins. In fact, that was one of the very reasons that the Chinese kept crickets in their homes; the insects acted as a sort of home security system: they stopped chirping when a person approached, so its silence gave an alert that someone was coming.
Crickets as Pests
But if you already have a home security system, or just prefer not to keep crickets in a cage, or have them in your home at all, the rest of this article discusses two common cricket species, how to get crickets out of the house, and how to keep them out.
Like millipedes and centipedes, crickets are considered to be only occasional invaders of homes and other buildings. That is because they prefer to live outdoors and don't survive well or breed indoors. However, they will enter structures in search of shelter if the weather gets bad, or if they just accidentally happen to hop through an open door, window, or other openings.
Because crickets are attracted to warmth, they are most likely to be found in kitchens or near sources of warmth, such as the furnace or water heater. Once inside, they also can burrow into cracks and behind baseboards.
The House Cricket (Acheta domesticus):
- Is about 3/4 to 1 inch long.
- This cricket has a light yellowish-brown body with 3 dark bands on the head and long, pointed wings.
- This cricket eats almost anything.
- Will chew on and damage fabrics, paper, rubber, and foods.
The Field Cricket (Gryllus spp.)
- Is 1/2 to 3/4 inch long.
- This cricket has a dark brown to black body with curved wings.
- It feeds on plants and fabrics.
- It is attracted to lights at night.
A cricket or two in the home will rarely cause damage, but high populations can be of concern because of their tendency to chew.
To control crickets in the home:
- If there are just one or two, place glue boards in the areas of the room where chirping is heard. Use corn meal in the center of the board as bait, and the cricket should be captured within a day or two.
- If the cricket can be found, it can be vacuumed up. The vacuum should then be emptied, or the bag was thrown away, outside the home.
If a heavy infestation has developed, some sprays and baits are available through home and garden stores, department stores, etc. Read the labels to select one that is registered for the control of crickets. As a general rule:
- Spray pesticides can be applied to entry points, baseboards, and in garage and basement areas.
- Baits can be placed in non-food areas.
But, for both, when using any chemical, be sure to purchase only those labeled for the insect you want to control and the area it is to be used, then read and follow all label directions.
Keep Crickets Out
Crickets can only enter the home if there is an opening for them to get in, and they can only survive if conditions allow. So, to prevent infestations:
- Caulk or seal all potential entry points, such as cracks in the foundation, and gaps around doors and low windows.
- Keep the foundation and perimeter of the home free of grass, weeds, and mulch.
- Never store firewood or other organic material or debris near the home, like crickets and other pests can use the wood for shelter, then make their way into the home.
- Reduce harborage by setting trash cans up on bricks.
- Use yellow sodium-vapor lighting outdoors rather than white or mercury vapor lights. When possible, place lights on poles with the lighting directed toward the door or area you wish to light. This will draw insects to the light source rather than to your opening door.
- Inside the home, reduce clutter, piles, etc. to reduce potential harborage and hiding areas.
