To hubby, whenever he sees a trail of ant crawling, it will be a mouth-watering mission. In fact, with such attitude, we barely see much many ants in our house now.
Pay attention to those old fitting. We been staying in this house for 10 over years and our kitchen fit in cupboard is that old too. As such ants will hide in those corner that are barely visible.
So when D sees ants, he will track down their nest and as such, he has managed to destroy at least 4-5 nest built in our home as of to date.
We also notice, all these nest are built in between the hinges of the cupboard or at the corner of the cupboard. Spray some Shieldtox there and it will definitely help.
Hope the above tips help.
