Temprid FX has two mix rates: 8 mL (0.27 fl oz) per gallon of water for the standard rate, and 16 mL (0.54 fl oz) per gallon for the high rate. Which one you use depends on the pest you’re targeting and the severity of the infestation.
Standard vs. High Mix Rates
The standard rate of 8 mL per gallon creates a 0.075% solution. This is the go-to dilution for most general pest control, including ants, spiders, and light to moderate cockroach problems. The high rate of 16 mL per gallon doubles the concentration to 0.15% and is designed for severe infestations, faster knockdown, and longer residual protection.
For cockroaches specifically, you can use anywhere from 8 to 16 mL per gallon depending on how bad the problem is. A few roaches in the kitchen might call for the standard rate. A heavy infestation with roaches appearing in multiple rooms warrants the full 16 mL.
Bed Bug Mix Rate
Bed bugs have a strict cap: 8 mL per gallon of water, no exceptions. You cannot use the higher 16 mL rate for bed bugs even in severe infestations. This limit is set on the product label and applies to every application.
Indoor bed bug treatments are limited to spot sprays and crack-and-crevice applications. You can treat along mattress seams, bed frames, baseboards, and furniture joints, but you cannot broadcast spray entire floors or rooms. Spot treating beneath furniture, in closets, and in storage areas is allowed.
Coverage Per Mixed Gallon
For outdoor and perimeter applications, the label specifies coverage based on 1,000 square feet of surface area. At the standard rate, you apply 8 mL of product per 1,000 square feet. At the high rate, it’s 16 mL per 1,000 square feet. How much water you use to deliver that product depends on your sprayer type.
With a hand pump sprayer, one gallon of mixed solution at the standard rate covers roughly 1,000 square feet of perimeter. Power sprayers use more water per square foot, so you adjust the concentration accordingly. For example, mixing 4.5 fl oz (133 mL) of Temprid FX into a 50-gallon tank and spraying at 3 gallons per 1,000 square feet delivers the correct standard rate.
For landscape plant bed broadcasts, use at least 2 gallons of diluted solution per 1,000 square feet to get adequate coverage into soil and mulch. Carpenter ant soil treatments require a much heavier volume: 1 gallon of dilution per 8 square feet of soil.
Indoor Application Restrictions
Temprid FX is not labeled for broadcast spraying indoors. You cannot spray entire floors, carpets, or open room surfaces. All interior use must be spot treatments or crack-and-crevice applications: think baseboards, behind outlet covers, under appliances, along door frames, and inside wall voids. You also cannot use it as a space spray or fogger.
Outdoor Application Rules
Outdoor use is more flexible but still has boundaries. You can treat the foundation of a building up to 3 feet above ground level. Eaves, soffits, and the undersides of doors or windows that are protected from rain by an overhang are also fair game. Around potential pest entry points, you’re limited to a spray band no wider than one inch.
You cannot spray directly onto sidewalks, driveways, patios, or other hard surfaces except as a spot or crack-and-crevice treatment. This restriction exists to prevent runoff into storm drains and waterways.
Retreatment Schedule and Annual Limits
You can reapply Temprid FX every 7 to 10 days if pest activity continues. Don’t spray more frequently than that.
The product label also sets a yearly maximum of 32 fl oz of concentrated Temprid FX per acre per calendar year. In practical terms, that works out to 118 gallons of mixed solution at the standard 8 mL rate, or 59 gallons at the high 16 mL rate, per acre per year. For most residential properties, this limit is unlikely to be an issue unless you’re treating a large lawn or landscape repeatedly throughout the season.
Drying Time and Re-Entry
After spraying indoors, keep children and pets out of treated areas until the product has completely dried, which typically takes about one hour. Outdoor applications take longer to dry, generally 4 to 6 hours, because of heavier application volumes and variable airflow. Once the product is fully dry on the surface, treated areas are safe for normal use.
