why should ants be squshed?

I think this depends on where the Ants are and what they are doing. If in the house track down where they enter and seal it or dust with pepper. If they are farming Aphids on a plant, Squirt water from a hose to wash off the Aphids and then when its dry use the pepper.or stand the plant if potted on a tray surrounded with water,raising the plant pot above the water so it is like on an island as it mustn't get waterlogged. ANTS are a life form and where possible avoid killing them. Their life style is so fascinating that they are more interesting than many plants.

I'm glad you said that, Poaanua, I was about to say - why should they be squashed? Are they a nuisance or dangerous across the pond?

and i third that, i avoid killing anything i don't have to (except slugs! lol) Have you ever seen the film Anz, Reii? think you may not want to squash them after seeing this.

I believe in the old addage of "live and let live" in most cases unless you are experiencing a negative impact. I have two sons and 3 grandchildren who are severely allergic to ant bites. Due to this issue, my entire place must be totally ant free. Every spring the hunt begins for all anthills.

That's a special case, though, Skippy. You wouldn't want ALL ants killed in other places away from your own environment, would you?
