If there are ants (or other creepy-crawlies) in a sink on Shabbat, what is permitted to do with them when using the sink? Here are some things i can think of:
- Intentionally avoid pouring water on them
- Don't think about it at all
- Pour water in their general area, but not specifically on any ant
- Pour water directly on them to get rid of them
1 is obviously good, but what about 2 and 3?
