The short, honest answer
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.
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.
General information, not veterinary advice. For a suspected exposure, contact your veterinarian or a pet-poison hotline. Verdict checked 2026-07-13 against the EPA label and veterinary toxicology.
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.

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.
NPIC cyfluthrin fact sheet; Bayer SDS
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
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
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.

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.
Bayer EPA label 432-1363 / 101563-213
What's in it — and what it does to pets
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.

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.
Remove pets and cover or disconnect aquariums
The label directs removing or tightly covering aquariums and disconnecting air pumps before indoor application.
Apply as a spot, crack-and-crevice, or general surface treatment
Apply per label directions to the areas insects travel, avoiding food-contact surfaces.
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.
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.

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
- Get your pet away from the treated area and any wet residue.
- Gently wipe wet residue off paws and fur to stop grooming ingestion.
- Do NOT induce vomiting unless a veterinarian or poison expert tells you to.
- Have the product name and EPA registration number ready.

Safer pet-friendly alternatives
Honest options that reduce or remove pet-toxicity — no affiliate hype, real caveats included.
Enclosed/tamper-resistant bait stations
SaferEnclosed 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
SaferNon-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
SaferBotanical / 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.

Pet-safe pest control in New Hampshire
Professional concentrates like Tempo SC Ultra deliver strong residual control but demand correct dilution and placement — which is why New Hampshire treats applying pesticides for hire as a licensed activity: it requires a commercial applicator certified through the NH Department of Agriculture, Markets & Food (NHDAMF) Division of Pesticide Control under RSA 430. Anchor Pest Services holds that NH licensing (License #782664) and provides pet-conscious treatment across Manchester, Nashua, Concord, and the surrounding towns, timing re-entry around the pets in your home.
