<human>: I'd like to know what's the best way to get rid of a roach infestation?
<bot>: The best way to get rid of a roach infestation is by using an insecticide spray specifically designed for roaches. You should also remove all sources of food and water, such as crumbs and standing water, which can attract more roaches. Additionally, sealing off any cracks or crevices that may provide entry points for the roaches can help prevent future infestations.
