The answer to 'cockroach prevention tips' is to take a proactive approach to keep cockroaches out of your home. Start by sealing any cracks and crevices where they could enter, using caulk or other sealants. Keep your kitchen clean by wiping up spills and crumbs immediately, and store food in airtight containers. Use boric acid or diatomaceous earth in problem areas to kill existing cockroaches and deter new ones from moving in.
It's also important to reduce moisture sources that attract cockroaches, such as leaky pipes or standing water. Regularly inspect and clean under sinks, behind appliances, and in other damp areas. Consider using dehumidifiers or fixing any plumbing issues to make your home less appealing to these pests.
