I had the same problem with ants before, and no matter how many DIY solutions I tried, they always seemed to come back after a while. What finally worked for me was engaging a professional pest control service. They were able to identify the source of the infestation and treat it properly, which made a huge difference. Since then, I've made it a habit to schedule pest control at least once a year to help keep my home pest-free and prevent future infestations. It's been well worth it for the peace of mind.
