Cucumber slices: Who knew cucumbers could repel insects? Simply arrange some cucumber slices on plates and watch those roaches scurry away!

Boric acid balls: Mix one tablespoon of boric acid with one tablespoon of sweetened condensed milk. Roll the mixture into small balls and place them in the areas where roaches are known to roam. Repeat the process after three weeks to eliminate the next generation.
Lemon eucalyptus essential oil: If you spot the early signs of a roach invasion, pour a few drops of this oil onto pieces of newspaper and position them in their favorite hangouts.
Lavender essential oil: Place 5 to 10 drops of soothing lavender essential oil on small pieces of cotton and put them in your cupboards. Remember to reapply daily.
White vinegar power: Spritz some white vinegar on the bottom of your walls, under your furniture, under the sink, and anywhere else roaches like to scuttle. The smell is a big turn-off for them!
