Store food properly: Cockroaches are attracted to open food containers, so store food properly. Keep food in airtight containers, and do not leave food out on counters or tables.

Take out the trash regularly: Cockroaches are attracted to garbage, so it is essential to take out the trash regularly.

Call a professional: If you have a severe cockroach infestation then call a professional cockroach pest control company. They use specialized equipment and techniques to get rid of the roaches and help prevent future infestations.
