Does alcohol kill roaches

Yes, alcohol can kill roaches by dehydrating them and disrupting their cellular functions. Isopropyl alcohol, in particular, can be effective when sprayed directly on the insects. However, while it may kill some roaches, it is not a comprehensive solution for infestations, as it doesn't eliminate eggs or the entire population. For effective pest control, it's best to use targeted insecticides or professional extermination methods.
