Okay this is proven to work and much safer if you have kids and pets.
We had an ant infestation over the weekend in my living room I mean they were swarming in through the heat vent, coming in through the base board and were in my throw rug where the baby plays.
I grabbed my can of Lysol and sprayed the lot of them killing them instantly! The house did NOT fill with toxic fumes you get from bug spray instead it smelled fresh and clean in my house.
I waited for the lysol to dry then vacumed up the dead ants and washed the floor!
No more ants!
Saves money, keeps the house clean and fresh and is safer for the kid's too. so if you have ants......grab that lysol and Kill them dead!
