The idea of slathering the legs of my bed with Vaseline doesn’t really appeal to me.
Many beds (like mine) have designs that don’t really lend themselves well to this. I have a sleigh bed which doesn’t have individual legs. It has two big pieces of wood at the head and the foot of the bed that touch the floor. So for each end of the bed I would need to coat all four sides of a piece of wood roughly 4.5 feet wide x 2 inches deep. I don’t want to damage the wood and I don’t want Vaseline on the carpet. I also don’t want it out where my pets can get to it.
If the above applies to you, what can you do? The Bedbug Beacon is a nice choice. You can see the most popular ways of catching bed bugs here.
