If crickets are chirping outside your window, showing up in the basement, jumping in the garage, or damaging your lawn, the first step is not buying a random spray. The right fix depends on which cricket you have and where it is active.
This guide explains the main cricket types US homeowners run into, how to tell them apart, what signs to look for, and which next step fits your situation: indoor traps and exclusion, basement moisture control, perimeter cleanup, or lawn-level mole cricket treatment.
Quick Answer: How to Identify and Control Crickets
To solve a cricket problem, match the cricket to the location. Indoor chirping and fabric damage usually point to house crickets. Damp basements and crawl spaces often point to camel crickets. Brown lawn patches, loose turf, or surface tunnels may indicate mole crickets.
- Crickets inside the house: reduce moisture, seal entry points, remove hiding spots, and use traps or indoor cricket products where activity is concentrated.
- Crickets around the foundation: thin mulch, remove debris, mow tall grass, adjust outdoor lighting, and treat the perimeter only when needed.
- Crickets damaging the lawn: check for mole crickets. They need soil-level treatment, not indoor traps or surface-only sprays.

Choose Your Cricket Problem
Use this quick table before choosing a treatment. Cricket control works better when the fix matches the species and location.
| What you notice | Likely cricket issue | Best next step |
|---|---|---|
| Chirping inside at night | House cricket or field cricket indoors | Use the indoor cricket control guide |
| Jumping insects in basement or crawl space | Camel crickets in damp areas | Reduce moisture, improve ventilation, seal gaps, and place traps in dark corners |
| Crickets gathering near doors, patio, or foundation | Field crickets or house crickets outside | Clean up hiding spots, change outdoor lights, and compare perimeter control products |
| Brown patches, loose turf, or shallow tunnels | Mole crickets in the lawn | Use mole cricket lawn treatment steps |
| You know you need treatment but not the product type | Product mismatch risk | Compare cricket traps, sprays, and lawn treatments |
What Are True Crickets?
Also known as true crickets, these insects are small to medium in size and found in nearly every region of the world except the coldest areas. True crickets belong to the family Gryllidae within the order Orthoptera, the same broad insect order that includes grasshoppers and katydids. They are characterized by round heads, cylindrical bodies, long antennae, and strong back legs built for jumping.
There are over 900 cricket species worldwide. The United States is home to about 100 of them, but only a handful regularly enter homes or damage property.
The 4 Cricket Types US Homeowners Encounter
Most cricket problems in the US come down to four main types. Knowing which one you have determines how to treat it.
| Cricket Type | Where You Find Them | Main Problem |
|---|---|---|
| House crickets | Basements, garages, warm indoor areas | Loud nighttime chirping, possible fabric damage |
| Field crickets | Yards, patios, foundations, lawns | Outdoor nuisance, occasional indoor invasion |
| Camel crickets | Crawl spaces, damp basements, garages | Damp-area activity and sudden jumping behavior |
| Mole crickets | Lawn soil, garden beds, turfgrass areas | Lawn and root damage, brown patches, loose turf |
Cricket Identification: What Do They Look Like?
Most crickets you’ll encounter are nocturnal — active in the evening and at night. They are typically black, brown, or tan, which helps them blend in with soil, mulch, and dark indoor corners.
Like most insects, they have six legs: four walking legs and two powerful back legs built for jumping. Long antennae attached to the head are used for smelling and feeling their surroundings. People often confuse crickets with grasshoppers because the body shape is similar — the easiest way to tell them apart is antenna length. Crickets usually have long, thin antennae, while grasshoppers usually have shorter antennae.
The body is flattened vertically. Wings, when present, lie flat on the back. Some species are completely wingless, and a few — like mole crickets — have wings but rarely fly.
What Do Crickets Eat and How Long Do They Live?
Crickets are scavengers and omnivores, which means they will eat many different organic materials. Common food sources include seeds, flowers, leaves, tree bark, and decaying plant matter. Some species are predatory and feed on smaller insects and other small invertebrates.
Diet varies by type. Field crickets eat ornamental plants, vegetables, and fruits. Tree crickets feed on aphids, making them somewhat beneficial. Bush crickets prefer flowers, leaves, and fruit. Camel crickets eat fungi, dead insects, and roots. Mole crickets feed heavily on grass roots and shoots — which is why lawn damage is their primary impact.
The average cricket lives about three months. Eggs hatch in 7–8 days, and nymphs go through several molting stages, called instars, before becoming adults. The exception is the mole cricket, which can spend winter deep underground and may have a longer life cycle depending on the species and climate.
Mole Crickets: The Cricket Type That Damages Lawns
Most crickets in this guide are surface-dwelling — they chirp at night, hide in dark corners, and sometimes wander into basements or garages. Mole crickets are different. They live underground, tunnel through lawns, and damage grass roots from below the surface.
If your lawn has brown patches that look like drought damage, loose turf that pulls up easily, or small raised tunnels near the soil surface, mole crickets may be the cause. Unlike house or field crickets, sticky traps and indoor sprays will not solve a mole cricket problem — they require lawn-level treatment with granules, bifenthrin concentrate, or beneficial nematodes. They are most active in early to mid-summer, when young nymphs feed close to the soil surface.
Common Signs of a Cricket Infestation
Crickets become a nuisance when they invade your home or damage your lawn. Here’s how to recognize activity before it spreads further.
Physical Signs of Indoor and Outdoor Activity
Indoor crickets prefer warm, dark, slightly damp areas. Common hiding spots include behind appliances, inside closets, under sinks, in basements and garages, and around trash bins. Outdoors, they hide in tall grass, mulch beds, woodpiles, and under outdoor furniture. They can be hard to spot during the day because they go silent under threat.
Loud and Persistent Nighttime Noise
The chirping comes from males rubbing their forewings together — a mating call to attract females. Females are silent. One or two crickets outside is normal background noise, but persistent loud chirping inside the home often means a male has gotten indoors.
Fabric Damage and Droppings
Indoor crickets may chew on silk, wool, cotton, and synthetic fabrics — especially items with sweat or body-oil stains. They may also leave small dark droppings on surfaces near their hiding spots. Crickets are not dangerous to humans or pets, but persistent indoor activity can damage clothes, linens, and stored fabrics.
Lawn Damage and Surface Tunnels
If you have brown patches, raised tunnel ridges, loose turf, or soft spongy areas in your lawn, you may have mole crickets. Damage often expands after rain or irrigation and may attract birds or other animals digging for the insects.
How to Get Rid of Crickets
The right control approach depends on which cricket type you have and where they are active.
- For indoor crickets, including house crickets and camel crickets: Start with sticky traps, moisture reduction, sealing entry points, and targeted indoor products if activity is persistent.
- For outdoor crickets, including field crickets: Yard cleanup and perimeter treatment can help reduce cricket activity around the foundation. Remove woodpiles, debris, dense weeds, and tall grass where crickets hide during the day.
- For mole crickets in the lawn: Use lawn-level treatment such as granules, bifenthrin concentrate, or beneficial nematodes applied directly to the soil. Surface sprays and indoor traps will not solve a mole cricket problem.
5 Prevention Tips: How to Keep Crickets Out of Your Home
- Seal entry points: Apply caulk to cracks around foundations, doors, windows, and utility penetrations where crickets can enter the home.
- Change outdoor lighting: Switch to sodium vapor or yellow “bug light” bulbs — crickets are far less attracted to these wavelengths.
- Reduce indoor moisture: Fix plumbing leaks, run dehumidifiers in basements, and ventilate damp areas properly to discourage camel crickets.
- Maintain your yard: Mow your lawn frequently, remove woodpiles and debris, and keep mulch beds thin near the foundation.
- Store fabrics properly: Keep wool, silk, and seasonal clothing in sealed containers if crickets are active indoors.
Interesting Facts About Crickets
They Are Harmless to Humans
Crickets don’t transmit diseases to humans or pets, and they don’t bite aggressively. Large house or field crickets may pinch if handled, but this is rare and harmless.
Only Male Crickets Make the Sound
Females are silent. Males have a specialized vein at the lower part of their forewings that acts like a scraper — the male pulls this wing against the upper surface of the opposite wing to produce sound, a process called stridulation.
The Chirp Has a Risky Purpose
Males chirp to attract females from long distances. But the male must be careful — chirping also attracts natural predators that listen for the same sound.
Some Species Can Fly
There are more than 100 species in the US, so it’s not surprising that some can fly and others can’t. Most species rely on their powerful hind legs to jump and run rather than flying.
You Can’t Easily Sneak Up on Them
Their legs contain sensitive vibration-detecting organs. When they sense footsteps or nearby motion, they fall silent and freeze as a survival mechanism.
Cricket Chirps Can Roughly Predict the Temperature
Known as Dolbear’s Law, this simple estimate is often associated with snowy tree crickets. Count the number of chirps in 15 seconds and add 40 — the result is a rough estimate of the temperature in Fahrenheit.
