How to get rid of ants indoors safely for my cat without pesticides?

You are right in saying that certain chemicals should be avoided around cats. This should include permethrins, pyrethrins, and any of the chemicals derived from these compounds. However, most studies have already shown that as long as your kitty isn't actively licking this chemical, being directly sprayed with it,or eating dozens of the ants killed by it, the level of toxic exposure required to cost significant harm or death in a cat is pretty unlikely. That is not to say that ultimately it would be safer to relocate your cat during the extermination process or use a different chemical that kills ants. There are many different insecticides that have very limited intoxication potential. If you have any concern about what to use, I would advise you to reference the pet poison healthline website. You can also call them if you want specific advise concerning your pet. Here's the website: http://www.petpoisonhelpline.com/ Good luck in your ant killing journey!

I would not use essential oils. There are many that are toxic and aren't safe to have around cats. Ant bait stations are safe for cats and you can find ones with low toxicity. I recommend getting those to kill the ants. I hope this helps!

I'm sorry to hear about the loss of your cat! How awful. It's very unlikely that the ant traps would have had anything at all to do this with this - borax is fairly non-toxic, and would require ingestion of a really large amount in order to cause any serious problems. Exposure to traces of it from simply being in the same area as the traps should not cause any issues at all. Again, I'm very sorry for the loss of your kitty.

Below is a link with information on some products that are safe for pets. Read the label before applying any products. You could also call an exterminator and ask that they use a pet friendly product. https://roachtreatment.com/pet-safe-roach-killers/

It depends what spray you used, with most spray it should be fine after 12 hours but some products have longer effect in the environment, i recommend to read the cautions that needs to be taken on the spray label.

You can use plain vinegar and water in a 50/50 dilution to clean most hard surfaces. Commercial products that are safe to use include Green Works wipes, the Seventh Generation line and the Mrs. Meyer's line of "eco-cleaners".

Hello. Most recipes I have seen recommend using 5 drops of peppermint oil to 16 oz water & a dash of soap, so check to make sure 10 drops will not be too strong for you. Just fill the bottle 1/2 way, add the 10 drops & see how it smells. If too strong, just fill the bottle the rest of the way with water. I do not think this will be a problem to any of your cats as long as the spray has a chance to dry before letting your cats back into the room. You can use the stronger dilution outdoors with no issues, but indoors, check to see how your cats react in just one area after the spray has dried. It cannot harm them once dry, but you certainly do not want anyone licking up any drips. Thanks for using Petco Pet Education Center, formerly Petcoach.
