Ants in the house

I don't like ants too much. At least those that tried to bite me, or crawled on me.

So, when I got home today, I saw a bunch of ants: by the sink, on the counter, on the walls, in my plants , and my oven! Ack !!! I tried to figure out what is getting them interested, because generally there are only a few scouts... or if they found food - there will be a line formed. Its sort of like in between scouting and food find. Think they are confused by bad information.

Not sure where they are coming in either :(

The attempt to get ride of them involves:

• Squeezing them individually. That was too slow.
  
• Spraying them with Chlorx
• Sqeezing them - after Chlorx was sprayed. They were still alive.
  
• Spaying them with those insect spray.
  

That worked. Tho its pretty poisonous. So I scrubbed the counter top with soap before i forget and eat stuff off it.

I left some ants in my garbage and tossed it out. Now I feel a bit bad. Is it better to have them killed than leaving them living in the garbage and die of a slow death? Sometimes I think about molds like that too...
