Not all of them. Sorry to burst your bubble, but peppermint is less effective against ticks and bed bugs. Those critters are just stubborn. For mosquitoes, though? Definitely. A 2019 study even found that peppermint oil repelled mosquitoes for up to 90 minutes—comparable to some DEET-based repellents. (Take that, chemical companies.)
And spiders? Oh, they hate it. I once sprayed a peppermint solution around my basement windows and saw a daddy longlegs do a full U-turn. It was like watching a cartoon character hit an invisible wall. Felt like a victory dance was in order. (I may have done one.)

One little warning before you go wild
Peppermint oil is super concentrated, so don’t use it on pets—especially cats. The menthol can mess with their breathing and cause drooling or worse. Stick to using it on surfaces, not on Fluffy. For yourself, always do a patch test, because some people’s skin reacts. (Mine loves it. You might be different.)
Also, if you’re growing peppermint in your garden, know that it spreads like a gossipy relative. It’s a rampant grower, so plant it in a pot unless you want your entire yard to smell like a candy factory. Not a bad problem to have, but still.
At the end of the day, peppermint is that friend who shows up, makes things better, and doesn’t ask for anything in return. It’s cheap, smells amazing, and turns your outdoor spaces into bug-free zones. So next time you’re under siege by mosquitoes, skip the chemical fog. Grab a leaf, crush it, and give those bugs the minty boot. Your skin—and your nose—will thank you.
Now go enjoy that burger without the buzzing. And if anyone asks why you smell like a candy cane? Just say it’s your secret weapon.
