Big black ants

My trailer is parked on a seasonal site. What can I use on the outside to TRY and keep black ants from getting into my unit. We keep all food in sealed containers and keep kitchen area clean but those pesky big black ants still come in for a visit. Thanks for any replies.

    Not all "large black ants" are carpenter ants. We have them here in the northwest and most of them are not carpenter ants. Take one in to a local agriculture extension office if you have one close. They can identify it. I would not take one in to a pest control office. They will tell you the end is near.

    I certainly would work to eradicate them as soon as possible. Have you seen any signs of sawdust in or around the trailer. That would be a sign that they are carpenter ants. Good luck.


    Yep, I keep forgetting we have all different kinds of critters across our great country. Here in PA, they are carpenters. I saw them carrying hammer and saws.

  • Some years ago I had a pop-up that got I infested with ants. They were eating their way through the roof insulation leaving styrofoam "sawdust" everywhere. I was able to completely eliminate them with a product called terro. It's a slow sweet poison that ants take to the nest and it slowly poisons the entire colony.
  • Those big black ants are generally not looking for your food. They are carpenter ants. They like to eat rotting wood. Google "carpenter ant bait". there are specific baits for them. Apply to areas where they are climbing up into the trailer (cords, tires, stabilizers, etc). Also make sure there are no tree limbs touching your trailer. They will use these as a bridge to get to the trailer. And ... they will fall off of branches above your trailer. Add some bait up there for those "dropping in" for dinner.
