Every fall, Riverside homeowners deal with the same problem. The temperatures drop slightly, and suddenly crickets are everywhere. In the garage. Under the doors. Behind the appliances. Chirping all night from somewhere inside the walls.
It is not a coincidence. It happens every year for the same reasons, and it will keep happening until you address what is actually drawing them in.
The short answer:
Crickets invade Riverside homes in the fall because cooling temperatures push them indoors in search of warmth, moisture, and light. Getting rid of them requires sealing entry points, reducing outdoor attractants, and treating both the interior and exterior of your home. One cricket is manageable. A full infestation requires professional pest control to resolve completely.
Here is exactly what you need to know.
Why Crickets Invade Riverside Homes Every Fall
Crickets are cold-blooded insects. When outdoor temperatures drop, their body temperature drops with them. At a certain point, survival instinct takes over and they start looking for warmth.
Riverside’s fall weather creates the perfect conditions for this. Daytime temperatures stay warm but nights cool down significantly, especially in inland areas. That temperature swing is exactly when crickets start moving toward homes.
Three things attract crickets to your property specifically:
Light
Crickets are strongly drawn to bright light. Exterior lights, porch lights, and light visible through windows all act as a beacon that pulls crickets toward your home at night.
Moisture
Crickets need moisture to survive. Leaky outdoor spigots, standing water, dense ground cover, and moist soil around the foundation all create ideal harborage conditions right next to your exterior walls.
Warmth
Once crickets are near your home, any gap in the structure becomes an invitation. Door sweeps, foundation cracks, utility penetrations, and gaps around windows are all common entry points.
Understanding why they are there makes the solution much clearer.

The Difference Between a Cricket Problem and a Cricket Infestation
A few crickets finding their way inside is normal, especially during fall in Riverside. An infestation is something different.
Signs that you have moved past a minor nuisance:
- Chirping coming from multiple areas inside the home
- Crickets visible during the day, not just at night
- Damage to fabric, paper, or stored food items
- Cricket droppings along baseboards or in corners
- Large numbers of crickets congregating around exterior lights after dark
House crickets and field crickets are the most common species in Riverside County. Both are capable of damaging clothing, upholstery, and stored goods if a population establishes itself indoors. If you are seeing consistent indoor activity, the problem is not going to resolve on its own.
How to Get Rid of Crickets in Your Riverside Home
Step 1: Seal Entry Points
This is the most important step and the one most homeowners skip. Treating crickets inside your home without sealing the entry points is like bailing out a boat without plugging the hole.
Do a thorough walkthrough of your home's exterior and look for:
- Gaps under doors and around door frames
- Cracks in the foundation or exterior walls
- Gaps around utility pipes and conduit entering the home
- Damaged or missing weatherstripping on doors and windows
- Openings around garage doors
Door sweeps and weatherstripping are inexpensive fixes that make a significant difference. Caulk any cracks along the foundation and around utility penetrations. This step alone reduces cricket entry dramatically.
Step 2: Reduce Outdoor Attractants
If crickets are congregating outside your home in large numbers, sealing entry points buys you time but does not solve the root problem. You need to make your property less attractive to them.
Practical steps to reduce outdoor cricket pressure:
- Switch exterior lights to yellow or sodium vapor bulbs, which are far less attractive to crickets than standard white or bright LED lights
- Move woodpiles, mulch, and dense ground cover away from the foundation
- Fix any leaky outdoor spigots or irrigation lines creating moisture near the home
- Keep grass and vegetation trimmed close to the house
- Remove debris, leaf piles, and clutter from around the perimeter
Reducing the population congregating outside your home means fewer crickets pressing against the structure looking for a way in.
Step 3: Address Interior Activity
If crickets are already inside, you need to treat the interior directly. Focus on the areas where crickets prefer to hide.
Crickets inside homes typically concentrate in:
- Garages and utility areas
- Basements and crawl spaces
- Behind appliances in the kitchen and laundry room
- Along baseboards in dark, undisturbed rooms
- Inside storage boxes and bins
Reducing clutter gives crickets fewer places to hide and makes treatment more effective. Keep stored items in sealed plastic bins rather than cardboard boxes, which crickets are known to chew through and nest in.
Step 4: Treat the Exterior Perimeter
The most effective long-term control comes from treating the exterior of your home before crickets make it inside. A barrier treatment applied along the foundation, around entry points, and across high-traffic areas creates a zone that eliminates crickets before they reach your walls.
This is where professional pest control services make the biggest difference. Over-the-counter sprays provide limited coverage and break down quickly. A licensed technician applies the right product in the right concentration to the right locations, and the barrier lasts significantly longer than a DIY application.
For properties with heavy outdoor cricket pressure, rodent control is worth reviewing at the same time. Large cricket populations attract rodents that feed on them, and a cricket problem that goes untreated can become a rodent problem by winter.
Will Crickets Go Away on Their Own After Fall?
Some will. As temperatures continue to drop into winter, cricket populations naturally decline. Adults die off and activity slows.
The problem is that fall is also when crickets lay eggs. If a population establishes itself in or around your home and completes its reproductive cycle, you are setting yourself up for the same problem next year but starting with a larger baseline population.
Addressing a cricket infestation in the fall, rather than waiting it out, breaks that cycle. It also prevents the fabric and material damage that a sustained indoor population can cause over the course of several weeks.
When to Call a Professional for Cricket Control in Riverside
DIY steps work well for minor cricket activity. If you are sealing entry points, adjusting your lighting, and keeping the perimeter clean, you will reduce the problem significantly.
Call a professional when:
- Crickets are visible inside daily despite your own efforts
- You are hearing chirping from multiple locations inside the walls
- The population outside your home is large enough that they are covering exterior walls or gathering in large groups near entrances
- You have identified damage to stored clothing, upholstery, or food items
