Is Demand CS Insecticide Concentrate Safe for Use Around Dogs?

Demand CS Insecticide Concentrate can be used safely around dogs, as long as you follow a few important precautions. The spray is only dangerous to dogs when it’s wet or being applied. Once it dries, the risk to your dog is very low because the active ingredient, lambda-cyhalothrin, binds tightly to surfaces and isn’t likely to transfer onto your pet’s fur or paws.

Keep your dog away from all areas that have just been treated until the spray is completely dry. “Dry” usually means there’s no more visible moisture or tackiness where you sprayed—this often takes about 2 to 4 hours, depending on how much was sprayed and the ventilation in the room. After everything is dry, it’s safe for your dog to come back into the space without extra precautions.

If your dog accidentally walks on a wet, treated area, wash their paws right away with soap and water. Never let your dog lick, chew, or roll in treated surfaces while it’s still drying. Used properly, Demand CS is effective for pest control and poses minimal risk to your dog once dry. Always keep any pesticides—and application equipment—stored out of reach of pets, too.

Is Demand CS Safe to Use Around Cats?

Demand CS Insecticide Concentrate can be used in homes with cats, but only if you follow safety steps carefully. The product is dangerous to cats (and other pets) if it is wet or if they come into direct contact with it before it has fully dried. Cats groom themselves by licking their fur and paws, so anything they touch could end up in their mouths. This is why keeping them completely away from treated areas while the spray is wet is essential.

Once Demand CS has dried completely (usually about a few hours, depending on ventilation and surface), it bonds to the surfaces and is much less risky for your cat. Never spray it directly on cats, their bedding, toys, litter boxes, or food/water dishes. Keep cats out of the area being treated and do not let them return until the surfaces are fully dry. Always read the label and directions, as misuse can cause harm. If you have kittens or cats with health issues, consult your veterinarian before using any insecticide in your home.

Safety of Demand CS Around Small Pets Like Hamsters and Guinea Pigs

Demand CS Insecticide Concentrate by Syngenta contains a chemical called lambda-cyhalothrin. This ingredient is very toxic to small pets such as hamsters, guinea pigs, mice, and similar animals. Because these pets are much smaller and more sensitive than dogs or cats, even tiny amounts left on surfaces, in the air, or on bedding can harm them. Exposure can lead to serious health problems like trouble breathing, tremors, weakness, and sometimes death. These animals often explore their environment with their nose and mouth and can easily come into direct contact with harmful residue.

For homes with small pets, Demand CS should not be used in areas where the animals live, roam, or have contact with surfaces. Simple separation (like moving a cage temporarily) is not enough because the chemical can linger for weeks, and particles can settle into bedding or food. Professional pest control specialists strongly recommend choosing methods or products specifically approved as safe for small mammals, or using natural pest control methods instead. Always keep all pesticides—especially sprays and concentrates—far away from areas that small pets use, and never apply around their living quarters.
