To prevent a bed bug infestation, it is important to keep your bedroom and bedding clean and hygienic. When traveling, keep your suitcase off the bed and check the mattress and sheets for any signs of bed bugs before sleeping. Use mattress protectors and regularly inspect and clean cracks, skirting boards, and furniture where bed bugs could hide. If you suspect a bed bug infestation, contact a professional pest control service to address the issue.
