Cricket killer sprays are the most direct and flexible tool for dealing with an infestation - whether you’re doing a perimeter treatment around your foundation, spot-treating inside a garage, or hitting crickets directly in the act. The spray format lets you apply insecticide precisely where crickets travel, shelter, and enter the home. In 2026, the best formulas combine fast contact knockdown with residual activity that keeps killing for weeks after application. We tested five of the top products to help you pick the right spray for your situation.

1. Ortho Home Defense Wand Spray - Best for Foundation Perimeter Treatment
Ortho Home Defense’s continuous spray wand is the easiest and most effective product for creating a residual barrier around your home. The wand reaches tight corners and crawl-space edges without bending over, and the bifenthrin formula dries to a colorless, odorless film that keeps killing for up to 12 months indoors on non-porous surfaces. Apply around doors, windows, baseboards, and the full exterior foundation line.
2. Raid Max Multi-Insect Aerosol - Best for Indoor Spot Treatment
For visible crickets inside the house, Raid Max aerosol is the fastest solution. A direct spray kills on contact within seconds, and the formula leaves a residual film on treated surfaces - under sinks, behind appliances, along baseboards - that intercepts crickets traveling through treated zones over the following weeks. The aerosol format is precise enough for tight spaces without over-applying to open room surfaces.
3. Hot Shot Ant, Roach & Cricket Spray - Best for Kitchen and Crawl Space Use
Hot Shot’s ready-to-use spray formula is specifically formulated for use in kitchens, bathrooms, and crawl spaces where crickets often shelter before moving into living areas. The water-based formula is lower odor than solvent-based aerosols and safe for use around food preparation areas when applied as directed. It’s also effective in crawl spaces and basements where cricket populations build up before infesting the main living areas.
4. Spectracide Terminate Spray - Best for Outdoor Broadcast Treatment
Spectracide’s Terminate spray connects to a garden hose for large-area outdoor application, making it the most efficient option for treating lawns, mulch beds, and the zone immediately around your foundation. The lambda-cyhalothrin active ingredient creates a broad kill zone for crickets in the soil and on vegetation, with residual activity that persists through light rain after a 24-hour cure period. Ideal for late-summer pre-migration treatments.
5. TERRO PCO Concentrate Spray - Best for Heavy Infestations
When you’ve tried consumer products and the infestation persists, TERRO PCO Concentrate is the step up you need. Mixed to label dilution in a pump sprayer, it delivers a higher concentration of active ingredients than ready-to-use products, with a dual-active formula (bifenthrin + zeta-cypermethrin) that handles resistant cricket populations. More economical per square foot than ready-to-use sprays and effective enough for rental properties and multi-unit situations.
What to Look For
- Contact vs. residual action: The best products do both - knock down visible crickets immediately and leave a residual that kills new arrivals. Check both claims on the label.
- Indoor/outdoor approval: Never use an outdoor-only concentrate spray indoors - use only products with explicit indoor approval for interior treatments.
- Application equipment included: Ready-to-use wand sprayers save setup time and reduce over-application; concentrates require a pump sprayer but cost less per treatment area.
- Odor and staining: Some oil-based formulas leave stains on fabric and painted surfaces - water-based formulas are safer for interior use on most surfaces.
Final Thoughts
For most homeowners, Ortho Home Defense’s wand spray is the single most useful product in this category - its ease of use and long residual make it the right default choice for foundation and indoor perimeter treatment. Pair it with Spectracide Terminate on the lawn and outdoor areas for complete coverage. If the infestation is severe or recurring, TERRO PCO Concentrate will deliver professional-grade results at a fraction of the cost of a pest control service call.
Frequently asked questions
What is the best spray to kill crickets instantly?+
Aerosol sprays containing pyrethroids - such as those in Raid Max or Hot Shot aerosols - provide the fastest contact knockdown on individual crickets. Direct spray contact kills within seconds. For longer-lasting control beyond instant knockdown, liquid residual sprays like Ortho Home Defense applied to baseboards and entry points continue killing crickets for weeks after the initial application.
Can I spray cricket killer inside my house?+
Yes, but only with products specifically labeled for indoor use. Read the label carefully - many outdoor concentrate sprays are not approved for indoor application. Indoor-approved products like Ortho Home Defense Indoor and Raid Max Aerosol are formulated at concentrations safe for interior use when applied as directed, with people and pets kept out of treated areas until the surface has fully dried.
How do I spray for crickets around my house foundation?+
Apply a residual spray in a band 2 to 3 feet wide along the base of the foundation and 2 to 3 feet up the wall. Also treat window wells, door thresholds, utility entry points, and the first few feet of ground adjacent to the structure. Apply in the evening when crickets are most active and temperatures are cooler. Repeat every 60 to 90 days during the warm season or after heavy rainfall.
