Pest control
None of this is expert advice. It's what people worked out for themselves, usually the hard way — what actually helped, and what they'd tell someone standing where you are. Take what fits and leave the rest.

Stay in bed with lights off for 5-10 minutes so mosquitoes settle nearby, then check walls for them.

One approach some take is to kill spiders immediately rather than letting them stay.
Some feel spiders are intruding on their space and should be removed if they do not 'pay rent'.
- This view includes extreme measures like flushing them down toilets or burning houses, which are not recommended as general advice.
one person who lived it
Strike a fly quickly from close range using a light, flexible object like a pen, aiming for the small margin of error above the surface where the fly takes off.
Flies tend to take off straight up, leaving a narrow window to hit them without hitting the table.
one person who lived it
- Spread your index and ring fingers on the surface near the fly while holding your middle finger back with another hand; release the hold so the middle finger snaps down to squash the fly.1
- Blow gently on a fly to force it to grip the surface tightly, making it easier to swat by hand.1
- Clap above a flying insect rather than swatting where it lands, aiming slightly behind its position as it lifts off.1
Slap flying insects with one hand rather than two to prevent air displacement that helps them escape.
Using both hands displaces air, which helps the insect escape.
- This method may not work against tropical mosquitoes.
one person who lived it
Turn off lights and open screened windows; flies will go to the lighter windows, then close the window while they are on the screen to trap them or let them escape through a bottom opening.
