Next, add some dish soap into the solution and transfer it to a spray bottle. You can now coat this mix in areas near your home where wasps are more likely to build nests.

This can be under the eaves, in your patio, the ledge, the roof your porch, crevices or anywhere else you deem fit.

With more than 20,000 active species, ants are probably one of the most commonly found insects on earth. Given their widespread presence, you’ve probably crossed paths with them at some point in time or the other.

Luckily, you don’t always have to spray chemical-laden bug sprays to keep ants at bay. Yes, Lemongrass can do the trick just as well (or even better).
