Shabbat: Permanent Knots
You may not tie permanent knots on Shabbat. A permanent knot is a knot intended to remain tied for at least 24 hours. Any strings you connect on Shabbat must be able to come undone by pulling on a single string, such as a bow.
Note Since opinions differ on what constitutes a permanent knot, we do not even tie knots that are intended to be untied, such as a double figure-eight knot.
Shabbat Key as Tie Clip or Brooch

Shabbat: Biting or Stinging Insects
You may trap insects on Shabbat that may hurt you, such as mosquitoes (without diseases) or bees that might sting you. You may also trap them or chase them away with bug spray. You may not trap insects that just annoy you, such as gnats or flies.
Shabbat: Insects that May Carry Diseases
You may kill mosquitoes and other insects on Shabbat if they carry deadly diseases (which makes the insects a danger, or sakana). You may kill insects that might carry deadly diseases even if you do not know for certain that they do.
Shabbat: Water Heater below 120° F
If you keep your water heater permanently set to less than 120° F (49° C) and if you turn off the heater before Shabbat, you may use that hot water on Shabbat. But you may not lower the setting just before Shabbat and then use hot water from that heater, since the water in the tank will still be hotter than 120° F for many hours (or even a day or more) after lowering the heater temperature.
Note If you will be using a large volume of hot water during Shabbat, consult a rabbi since the heating element might inevitably be turned on and that would be forbidden on Shabbat.
