Cucumber repels cockroaches.
Don't throw away the remaining cucumber heads after cutting vegetables, so that you can continue to use the residual heat to drive away cockroaches. Put the cucumber head in the cupboard where the food is stored, and the cockroach will not dare to come near it again. If the taste of cucumber has faded after a few days, you can cut the cucumber vertically and let it continue to emit this taste.
