Why are there ants in your kitchen? Do you need to do a thorough clean and put away of foodstuffs rather than reach for a spray that will fill the room with toxic vapours?
If you need to kill ants, equal parts of borax and icing sugar will be effective with no danger to the air you breathe; however, keep out of reach of children and pets as borax is poisonous.
If a bowl of pet food is the attraction, place the feeding bowl in a saucer of water. The moat effect will prevent ants reaching the food.
Ants are repelled by wiping benches with vinegar. Eucalyptus oil is a deterrent too.
To destroy an ant nest, flood it repeatedly. Alternatively, using a bucket, blend together half a cup of lime with a generous amount of detergent. Now fill the bucket with very hot water and pour carefully down the nest’s entrance holes.
