Is Tempo SC Ultra Premise Spray by Bayer Safe for Pets?

Use with caution
Tempo SC Ultra is a professional-grade pyrethroid (beta-cyfluthrin) sold as a concentrate that gets diluted with water before spraying — it isn't used straight from the bottle the way a consumer aerosol is.Once diluted and applied, it follows the same broad pyrethroid pattern as other products on this hub: dogs generally tolerate the dried residue reasonably well, but cats are the most sensitive common pet because they lack the liver process that clears pyrethroids efficiently, and the label explicitly states this product is extremely toxic to fish and aquatic invertebrates. If it's applied indoors, the label directs removing or tightly covering aquariums and disconnecting air pumps. Keep every pet off treated surfaces until fully dry, and call your vet or a poison hotline if a pet licks wet residue or shows drooling, twitching, or tremors.

The verdict for pet owners

The short, honest answer

Pet-safety score
50out of 100
Use with caution

The score rolls up every per-species verdict below, weighted by the honest exposure that matters — a chewed-open tube, not a hidden dab — and is checked against the EPA label and veterinary toxicology.

The verdict
Use with caution

A concentrated professional pyrethroid — potent undiluted, but the applied spray is a diluted residue. Cats, birds, and fish still need real caution.

Tempo SC Ultra is a suspension-concentrate pyrethroid (beta-cyfluthrin 11.8%) meant to be mixed with water — typically diluted many times over — before it's sprayed, unlike the ready-to-use aerosols elsewhere on this hub. Once mixed and applied, the residue behaves like other pyrethroid sprays: dogs generally tolerate labeled use once dry, while cats remain the sharpest exception because they can't efficiently clear pyrethroids, and the label itself flags this product as extremely toxic to fish and aquatic invertebrates. Because it's a professional-line concentrate, correct dilution and placement matter more here than with a pre-mixed consumer aerosol.

Safety by pet

It's not one answer — it's one per animal

Cats, birds, and fish routinely differ sharply from dogs. That contrast is the whole point of this scorecard, and no manufacturer page draws it.

DogsCaution

Generally tolerated once the diluted residue is fully dry

Dogs clear pyrethroids like beta-cyfluthrin relatively well, and the concentrate is heavily diluted before application, which lowers the applied concentration compared to the undiluted product. The main risk remains a dog licking wet residue before it dries. Keep dogs off treated surfaces until dry.

CatsAvoid
Cats differ — added blood-disorder risk

Keep cats off until fully dry and ventilated

Beta-cyfluthrin is a Type II pyrethroid, and cats lack the efficient liver glucuronidation that lets other mammals clear these compounds. Wet residue on paws or fur is then ingested during grooming, so cats should be kept out of treated areas until surfaces are completely dry.

Merck Veterinary Manual pyrethroid toxicosis

Small mammalsCaution

Remove during application and until dry

Small mammals housed near baseboards or floor level where residue settles should be moved out of the room during treatment and until the area is dry and ventilated.

NPIC cyfluthrin fact sheet

BirdsAvoid

Keep birds out of treated rooms; SDS notes transient hyperactivity typical of pyrethroids

Bayer's own safety data sheet notes transient hyperactivity effects typical of the pyrethroid class, and birds' respiratory systems are broadly sensitive to sprays and airborne residue. Remove birds before application and ventilate before their return.

FishAvoid

Extremely toxic to fish — cover or remove aquariums and disconnect air pumps

The product label explicitly states it is extremely toxic to fish and aquatic invertebrates, and directs removing or tightly covering aquariums and disconnecting aerators before indoor application.

The chemistry, in plain terms

What's in it — and what it does to pets

Beta-cyfluthrin
11.8% concentrate (diluted before application) · Pyrethroid (Type II)Broad-spectrum residual insecticide
Beta-cyfluthrin

A Type II pyrethroid that overstimulates the nervous system in sensitive animals, producing drooling, tremors, and hyperexcitability in cases of significant exposure. It is sold as an 11.8% concentrate but is diluted substantially with water before spraying, which lowers the concentration pets actually contact once dry. It is extremely toxic to fish and aquatic invertebrates and highly toxic to bees per the label.

The actionable core

How to use it safely around pets

This is a professional suspension-concentrate product, mixed with water at a labeled rate (commonly a small amount per gallon) before spraying — correct dilution and placement matter as much as drying time for pet safety.

Mix and apply strictly to the labeled dilution rate

Follow the product label's dilution instructions exactly; this is a concentrate, not a ready-to-use spray, and over-concentration raises pet-contact risk.

Watch out
This product is intended for licensed or experienced applicators — DIY use should follow the label precisely.

Remove pets and cover or disconnect aquariums

The label directs removing or tightly covering aquariums and disconnecting air pumps before indoor application.

Watch out
This step is explicit on the label, not a general precaution — don't skip it for indoor use.

Apply as a spot, crack-and-crevice, or general surface treatment

Apply per label directions to the areas insects travel, avoiding food-contact surfaces.

Watch out
Do not apply to surfaces pets eat or drink from.

Keep pets off until fully dry

Once dry, the residue is far lower-risk than wet product. Let the treated area dry completely and ventilate before pets return.

Watch out
Residual activity can last up to roughly 3 months — treated surfaces stay active insecticide zones during that window even once dry, so avoid repeat wetting/reapplication pets could contact.
The re-entry rule

Keep all pets off treated surfaces until the diluted spray is fully dry and the room is ventilated.

Follow the product label, which is the legal authority; treat wet residue as the primary hazard window.

Cats, birds, and fish warrant extra caution and ventilation time; disconnect aquarium air pumps before any indoor application.

Let a licensed applicator handle dilution and placement

Anchor's NH technicians apply professional-grade products like this one at the right concentration, in the right spots, away from pets.

If something's off

Symptoms to watch for

A sign, its urgency, and what to do — never a diagnosis. When in doubt, the emergency panel below is one tap away.

  • Drooling or hypersalivation

    Often the earliest sign in cats

    Moderate
  • Paw flicking or ear/skin twitching

    Moderate
  • Vomiting

    Moderate
  • Tremors

    Serious
  • Hyperexcitability or agitation

    Serious
  • Seizures

    Most likely in cats with significant exposure — seek emergency care

    Emergency
If your pet was exposed

Act now — call a vet or a pet-poison line

Do not induce vomiting unless told to

If your pet contacted this product, act now — bring the label or container when you call. This page is general information, not veterinary advice — for a suspected exposure, contact your veterinarian or ASPCA Animal Poison Control (888-426-4435) right away.

What each situation calls for

  • Your pet licked or walked through wet residue

    Wipe the residue off paws/fur with a damp cloth to stop further grooming ingestion, then call your vet or a pet poison hotline for guidance. Do not induce vomiting unless a professional tells you to.

  • Your cat is drooling, twitching, or tremoring after being in a treated room

    Treat as urgent — cats are the most pyrethroid-sensitive common pet. Call your vet or ASPCA Animal Poison Control immediately and bring the product label or container.

  • A fish tank was in the treated room during application

    If the air pump wasn't disconnected or the tank wasn't covered, contact an aquatic veterinarian or specialist promptly — beta-cyfluthrin is extremely toxic to fish even at trace levels.

In the next 60 seconds

  1. Get your pet away from the treated area and any wet residue.
  2. Gently wipe wet residue off paws and fur to stop grooming ingestion.
  3. Do NOT induce vomiting unless a veterinarian or poison expert tells you to.
  4. Have the product name and EPA registration number ready.
  5. Call your veterinarian or one of the hotlines below.
Lower-risk options

Safer pet-friendly alternatives

Honest options that reduce or remove pet-toxicity — no affiliate hype, real caveats included.

Enclosed/tamper-resistant bait stations

Safer

Enclosed bait (kept out of pet reach)

The active is sealed inside a station rather than sprayed across surfaces pets contact, sharply reducing exposure.

Still contains an insecticide — place where pets and children can't pry them open.

Mechanical exclusion + sanitation

Safer

Non-chemical

Caulking entry points and removing food/moisture sources reduces the underlying pest pressure with zero pet toxicity.

Slower than a residual spray; best paired with targeted baiting.

Plant-based (EPA 25(b) minimum-risk) sprays

Safer

Botanical / minimum-risk

A lower systemic-toxicity profile for mammals than a concentrated synthetic pyrethroid.

Not "harmless" for cats — concentrated essential oils can still cause irritation; let surfaces dry.

Professional pet-conscious treatment (Anchor Pest Services)

Safer

Licensed professional service

Correct dilution, targeted placement, and re-entry timing are exactly what a licensed applicator manages — this is a professional-line product best handled by one.

A service, not a product — request a pet-safety-focused plan.
