Leaving upstairs windows open at night is generally safer than downstairs ones due to reduced accessibility, but still poses risks like burglary, animal entry, or weather damage, so using window restrictors for a small gap, ensuring windows aren't easily reachable (e.g., near trees/roofs), and having security measures like alarms are recommended for balancing fresh air with security.
Keep windows shut at night – Most spiders are nocturnal, so keep windows and doors closed while you sleep to prevent them from getting into your home at night.
Sleeping with the window open can bring in fresh air and help regulate room temperature, but it may also expose you to allergens, outdoor pollutants, noise, and potential safety risks.
Keep all doors and windows closed and locked. An open window or door is an opportunity for burglars. Burglars are also quick to spot weak locks that may be easily forced open.
Generally, if your house is decently insulated, keep the windows and blinds closed when the sun is shining. Open the windows in the evening and at night. More specifically, keep the windows closed when the outside temperature is hotter than it is inside, and open the windows when it's cooler outside than inside.
In addition to dry air, sleeping with the window open can expose you to allergens that can be easily inhaled during sleep, notes Dr. Laren Tan, a pulmonologist and director of Loma Linda University Comprehensive Program for Obstructive Airway Diseases.
If you have a two-story home, use the stack effect to your advantage. Hot air rises, so opening upstairs windows along with downstairs windows creates a natural chimney effect. This pulls cool air in through lower windows and pushes warm air out through upper windows.
Select windows that are less accessible to potential intruders. Second-floor windows or windows that are difficult to reach from the ground are generally safer to leave open. If you have a multi-story home, favor the higher windows for nighttime ventilation.
Leaving on lights at all times doesn't seem to be an effective way to deter crimes. With a little planning and some home automation equipment, you can use lighting to your advantage and get better peace of mind.
1. Home Security Cameras. Our best deterrent for burglars is the presence of an outdoor security camera. Having cameras mounted around your exterior home is a great way to prevent burglars from entering your home!
Other windows, such as sliding sash windows, can be fitted with an additional locking sash to allow for a breeze while providing security. Install an anti-lift device to prevent windows from being lifted out of their frames. Use motion-detector spotlights in areas near windows to scare off potential burglars.
The top reason people sleep with their bedroom window open is controlling room temperature. People in cold states are more likely to sleep with a window or door open. People in the warmest states are more likely to sleep with windows and doors closed.
Sleeping with your bedroom door closed is a practice that significantly improves your chances of surviving a house fire. According to the FSRI, closing your door can greatly decrease carbon monoxide levels from 10,000 PPM to 1,000 PPM when compared to leaving it open.
Spiders hate strong, pungent smells, especially essential oils like peppermint, tea tree, and lavender, as well as scents from citrus (lemon, orange), cinnamon, eucalyptus, and cedar, which disrupt their senses. You can deter them with DIY sprays using these oils mixed with water, or use plants like basil and marigolds, or even vinegar, though vinegar's effect is temporary.
Spiders aren't directly attracted to light. Unlike moths and other night-flying insects, spiders are not drawn to luminous objects. However, they are smart predators and understand that other insects are attracted to light. Therefore, they often build their webs near light sources in order to capture their prey.
You should never squish a spider because it can release dozens of baby spiders if it's a mother carrying eggs, attract pests with released pheromones, cause allergic reactions from its internal fluids, leave stains and odors, and you'd be killing a beneficial predator that controls other insect populations. Most spiders are harmless to humans, and squishing them can backfire, worsening pest problems or causing messes.

Leaving Lights On Can Have The Opposite Effect
“A light in your home typically signals that someone is there, but in the middle of the night, it can also give the opposite impression—making it look like you're out of town,” MacDowell says.
Signs Your House Might Be Marked for Intruders
Opening the windows while we sleep is a great way to stay cool, breathe fresh air, and sleep soundly through the summer. However, this blissful rest can easily be disturbed by hovering bugs making their way indoors at night.
Sleep Quality
One of the main reasons for sleeping with a bedroom window open is that doing so can improve our quality of sleep, ensuring we wake up feeling fully rested. Scientists have found that a room temperature between 16° and 18°C is ideal for sleeping at night, although this varies by individual.
It's a common misconception that turning off the AC and opening windows at night in summer is more cost-effective. But this isn't always the case. As a general rule, if humidity levels are above 65% outdoors, then it's best to keep your windows shut.
10 Simple Actions to Take to Protect Your Home from Heat
Here's the thing: It's normal for your AC to run continuously during hot summer months. You see, on extremely hot days—we're talkin' high 90s to 100s—your system needs to keep up with the incoming heat. To do that, it will run longer in order to maintain a constant, desired temperature in your home.
