Every spring there is a surge of request asking for help to get rid of sugar ants in RVs. Sugar ants are virtually harmless, they don't bite or really do anything other than swarm your RV looking for what they love, sweet stuff. If you ever spill anything sweet on any surface in your RV you will instantly know how they got their name. You will see swarms of these little critters appear seemingly overnight and it can be a little overwhelming!
Take heart. There is a simple way to get rid of them. It's not instant, but it is safe and effective and cheap!
Sugar ants have a sophisticated way in which they communicate a "sweet find" to the rest of their nest. When a single ant finds something good to eat, it immediately shares it's location with all the others in the nest, and they all do the same. They march (often in a single, orderly black line that you have to see to believe) to the source and they devour it.
The ants gleefully gorge on the syrup and transport it back the to their nest, feeding it to all the others. Pretty genius to have them help you kill the nest, right? Yes, it does take a day or two or even three. You will see an alarming swarm of ants all over the traps-and you will be tempted to nuke them with ant spray. DON'T! They will keep to themselves, focused on harvesting the deadly nectar and rushing it back to the nest. Let them do their job. Then one morning, you will find they are GONE! I mean GONE. Not one. It's magic.
If you are transient and not staying more than a day or two, this method is not very helpful. Just know that the ants will go away after you leave. They will not breed in your coach and multiply. This is when spray might be a little more helpful.
