That headline is almost certainly an exaggeration.
There is no household mixture that will guarantee you’ll “never see flies, mosquitoes, or cockroaches again.” These pests have different behaviors and habitats, so a single recipe rarely works well against all of them.
Common ingredients in viral recipes
Posts like this often use combinations of:
- Vinegar
- Sugar
- Baking soda
- Lemon
- Essential oils (peppermint, citronella, eucalyptus, clove)
- Dish soap
Some of these can have limited effects:
- Sugar + liquid can attract and trap some flies.
- Citronella and some other essential oils may help repel mosquitoes temporarily.
- Dish soap can be used in homemade traps for certain insects.
Why they usually don’t solve the problem
- Mosquitoes breed in standing water, so eliminating breeding sites is more important than indoor scents.

What actually works best
For mosquitoes
- Remove standing water.
