Human: How do I keep bugs from coming in through my windows?

Assistant: 
Hm! That’s a bit of an interesting question, and the answer can vary a lot depending on exactly what you mean by “bugs”.  Are you talking about pests, specifically mosquitoes, or any kind of bugs?  If it’s just mosquitoes, you could try using a DEET-based repellent or an electronic bug repellent, but what bugs are you trying to avoid, exactly?  If you’re concerned about spiders, a citrus-based bug spray is usually effective. 
Is this a serious question?  Or are you feeling jumpy or something and trying to figure out what to worry about?  A far more serious concern is the danger of smoke inhalation and carbon monoxide poisoning, especially in winter when people use space heaters, because there are more people in the house and the heating system uses more gas and oil.
