Thank you for reaching out with your question about the safety of Terror Ant Killer Spray for pets.

For your safety, we recommend that you do not allow adults, children, or pets to enter the treated area until the spray has dried. Additionally, do not allow children or pets to contact treated surfaces until the spray is fully dry. Please also ensure that the product is applied in a way that avoids direct contact with adults, children, or pets, including any potential drift.

Following these precautions will help ensure the safety of everyone in your household.

If you have any further questions or need additional information, please don't hesitate to contact us.

Thank you for reaching us. Ant Killer spray kills ants on contact and continues to kill them for up to 6 weeks. The spray can also protect against scorpions, crickets, spiders, cockroaches, silverfish, centipedes, and Asian lady beetles, however, it doesn't work on wasps.

Hi, thank you for reaching us. Do not apply the product in areas where food will be placed, prepared, or consumed. It is safe for pets after it dries. needs to be reapplied after you wash the floors. There is no need to reapply it after vacuuming.

We recommend testing the product in an inconspicuous area before applying it to painted surfaces. Spray until the surface is slightly wet but not to the point of run-off. Please note that over-application may cause damage.

The TERRO® Ant Killer Spray has a light scent, but it is not designed to leave a strong lingering odor after application.

It should not be sprayed directly on electrical wiring, inside outlets, or into sockets. Apply it only to cracks, crevices, and surfaces where ants are active, following the directions on the label.

When sprayed directly on ants, it kills them on contact. It can help control visible ants and treat areas where they travel, but it is not intended to reach or eliminate an entire nest deep inside walls or structures.

For ants in a newly installed lawn, a granular outdoor ant control product is usually the best option because it can treat the mounds without putting excess liquid on the sod. TERRO® Ant Killer Plus can be applied to lawns and around the perimeter areas when used as directed.

If you prefer a spray, avoid overapplying directly to fresh sod until the grass is fully established. Always follow the label instructions for application rates and watering directions to help protect the lawn.
