RV camper problem #47: Ants in RV

Ants in RV? Are you dealing with an ant infestation in your RV? Ants can quickly become a nuisance when they invade your home on wheels. I was traveling for a few weeks (without my Airstream that I’m usually living in full-time) and when I came back, not only did I not have any coffee, wine, or food, but I also had an infestation of ants!
Not only are they unsightly, but they can also damage the structure of your RV and pose a threat to your health and safety. Luckily, there are several effective methods for getting rid of ants in your RV. In this article, we’ll explore some tips and tricks for preventing and eliminating ant infestations, so you can get back to enjoying your travels without any unwanted guests.
Ants can enter your RV through even the smallest cracks and gaps, making it difficult to keep them out. Once inside, they can establish colonies and cause damage to your RV’s electrical systems and structure. Additionally, ants can contaminate your food and create unsanitary conditions. Therefore, it’s important to take immediate action when you notice signs of an ant infestation, such as ant trails, nests, or swarmers. With the right approach and a little bit of patience, you can successfully eliminate ant infestations in your RV and prevent them from coming back in the future.
How did ants get into my RV?
Ants can enter an RV through a variety of entry points. Here are some of the most common entry points for ants:
- Cracks and gaps in the exterior walls: Ants can enter through any small cracks, gaps, or holes in the exterior walls of an RV.
- Open windows and doors: Ants can easily enter through open windows and doors. It’s important to keep windows and doors closed when possible.
- Vents and air conditioning units: Ants can enter through vents and air conditioning units on the roof of the RV. Make sure to seal these areas off to prevent ants from entering.
- Plumbing and electrical connections: Ants can enter through plumbing and electrical connections that are not properly sealed.
- Wheel wells and axles: Ants can enter through the wheel wells and axles of an RV. Make sure to check these areas and seal any gaps.
- Anywhere food is stored or prepared: Ants are attracted to food and will enter the RV through any area where food is stored or prepared. Make sure to keep these areas clean and free of food debris.
By identifying and sealing off these common entry points, you can help prevent ants from entering your RV in the first place.
Identifying the specific type of ant that has invaded your RV can help you choose the most effective method for controlling the infestation. If you’re not sure what type of ant you’re dealing with, a pest control professional can help identify the ant species and recommend appropriate treatment options.
How do I get rid of ants in an RV?
Ants can be a nuisance when they invade an RV. Here are some steps to get rid of them:
- Identify the source: Look for where the ants are coming from and try to identify the source of the infestation.
- Clean the RV: Thoroughly clean the RV, paying special attention to the kitchen and food storage areas. Make sure to remove any food debris, spills, and crumbs that might attract ants.
- Seal entry points: Check for any cracks, gaps, or holes in the RV and seal them off. This will prevent ants from entering the RV.

- Use insecticides: Use insecticides to kill any remaining ants. You can use a spray or dust insecticide specifically labeled for ants. Be sure to follow the instructions on the label carefully.
- Repeat: Repeat steps 2-5 as necessary until the ant infestation is completely eliminated.
It’s important to remember that prevention is key to avoiding future ant infestations. Keep the RV clean and free of food debris, and seal off any potential entry points.



What kind of ants do I have in my RV?
Several species of ants can invade RVs, but some of the most common types of ants that are found inside RVs include:
- Argentine ants: Argentine ants are small, dark-colored ants that are common in many parts of the United States. They are attracted to sweet foods and can establish large colonies with multiple queens.
- Odorous house ants: Odorous house ants are small, dark-colored ants that emit a strong, unpleasant odor when crushed. They are attracted to sweet and greasy foods and can establish large colonies with multiple queens.
- Carpenter ants: Carpenter ants are larger ants that are typically black or dark brown in color. They do not eat wood but can damage the structure of an RV by tunneling through it to create nests.
- Pharaoh ants: Pharaoh ants are small, light-colored ants that are attracted to sweet and greasy foods. They can establish large colonies with multiple queens and can be difficult to control.
- Pavement ants: Pavement ants are small, dark-colored ants that are commonly found in urban areas. They are attracted to sweet and greasy foods and can establish colonies under pavement, rocks, and other outdoor structures.
How does ant bait work (and is it safe to use in an RV)?
Ant bait works by using a slow-acting insecticide mixed with a substance that attracts ants, such as sugar or honey. The ants are attracted to the bait and carry it back to their nest to share with the other ants. As the ants feed on the bait, they also consume the insecticide, which is then spread throughout the colony. This leads to the eventual elimination of the entire ant colony (but it does take some time to wipe out the ant colony)
Ant baits are generally considered safe for use around pets when used according to the label instructions. However, it’s always a good idea to take some precautions when using ant bait around pets. For example, you can place the bait in areas that are inaccessible to pets, such as under appliances or furniture. You can also use bait stations that are designed to keep the bait contained and inaccessible to pets. Additionally, it’s a good idea to keep an eye on your pets to make sure they don’t come into contact with the bait. If you have any concerns about using ant bait around your pets, you should consult with your veterinarian or a pest control professional.
What chemicals are used in ant bait traps and insecticides?
The chemicals used in ant bait traps vary depending on the specific product, but some common active ingredients include:
- Boric acid: Boric acid is a natural compound that is toxic to ants. It works by interfering with the ant’s digestive system, causing it to starve to death.
- Hydramethylnon: Hydramethylnon is a chemical compound that is toxic to ants. It works by disrupting the ant’s metabolism, causing it to die of starvation.
- Fipronil: Fipronil is a chemical insecticide that is toxic to ants. It works by disrupting the ant’s nervous system, causing paralysis and death.
- Abamectin: Abamectin is a chemical compound that is toxic to ants. It works by interfering with the ant’s nervous system, causing paralysis and death.
Ant bait traps typically use a small amount of these chemicals mixed with a substance that attracts ants, such as sugar or honey. The bait is then placed in areas where ants are likely to be found, such as along ant trails or near entry points.
It’s important to use ant bait traps according to the label instructions to ensure safe and effective use. Keep in mind that while ant bait traps are generally considered safe when used as directed, they can still be harmful if ingested by pets or small children. Be sure to place bait traps in areas that are inaccessible to pets and children and store them out of reach when not in use.
How long does it take for an ant bait trap to work?
Don’t expect ant bait traps to work overnight. in fact, you may actually see MORE ants after putting down a few of the ant bait traps in your RV (I know I did!). While it may be frustrating to see more ants around the ant bait traps, DON’T kill them, otherwise, you are defeating the whole purpose of the ant bait traps, which is for the ants to take the bait back to the ant colony, where it can kill the rest of the ants.
This tip was hard for me to follow on the first day…I set the ant bait traps and checked back a couple of hours later and it looked like the ants were in line for an all-you-can-eat buffet at the bait traps! WFT?!? Fortunately, I re-read the package inserts and realized that the entire point of the ant bait traps was to ATTRACT the ants to eat the insecticide and then keep them alive long enough to bring the insecticide back to the ant colony. So good thing I didn’t start spraying them. Two days later now, and 99% of the ants are gone, with only a few still wandering around (so I’ve repositioned the ant bait traps)
The time it takes for an ant bait trap to work can vary depending on the type of bait and the severity of the ant infestation. In general, ant bait traps are designed to work slowly, allowing the ants to carry the bait back to their colony and share it with other ants. This slow-acting approach can take several days to several weeks to eliminate the entire ant colony.
After placing an ant bait trap, you may notice an initial increase in ant activity as the ants are attracted to the bait. This is a normal part of the baiting process and should subside as the bait starts to take effect.
It’s important to be patient when using ant bait traps, as it can take some time for the bait to work. Additionally, it’s important to avoid using insecticides or other ant control methods while using ant bait traps, as this can interfere with the baiting process and reduce the effectiveness of the traps.
If you’re concerned about the effectiveness of an ant bait trap or if you have a severe ant infestation, it may be best to consult with a pest control professional for more effective treatment options.
Does water and vinegar work to keep ants out of an RV?
Water and vinegar may help repel ants to some extent, but it is not the most effective way to keep them away from your RV. Vinegar is acidic and can disrupt the pheromone trails that ants use to communicate with each other. However, this effect is only temporary, and the ants may return once the vinegar scent dissipates.
To effectively keep ants away from your RV, it’s best to use a combination of methods, including:
- Cleanliness: Keep your RV clean and free of food debris, spills, and crumbs that might attract ants.
- Sealing entry points: Seal off any cracks, gaps, or holes in the RV to prevent ants from entering.
- Ant bait: Use ant bait traps around the RV to attract and eliminate ants.
- Insecticides: Use insecticides to kill any remaining ants. You can use a spray or dust insecticide specifically labeled for ants.
- Natural remedies: Some natural remedies that can be effective at repelling ants include peppermint oil, cinnamon, and diatomaceous earth. These substances are non-toxic and safe to use around pets and children.
Are there natural remedies for keeping ants out of your RV
Natural remedies can be effective at repelling ants because they contain substances that disrupt the pheromone trails that ants use to communicate with each other. Here are some examples of natural remedies and how they work:
- Peppermint oil: Peppermint oil contains compounds that have a strong odor that repels ants. When applied around the perimeter of an RV, the strong scent of peppermint oil can disrupt the pheromone trails that ants use to communicate, making it difficult for them to find their way into the RV.
- Cinnamon: Cinnamon has a strong scent that can also disrupt the pheromone trails of ants. Sprinkling cinnamon around the RV or placing cinnamon sticks near entry points can help repel ants.
- Diatomaceous earth: Diatomaceous earth is a natural powder made from the fossilized remains of diatoms. The powder is abrasive and can damage the exoskeletons of ants, causing them to dehydrate and die. When sprinkled around the RV or applied to entry points, diatomaceous earth can be an effective barrier against ants.
It’s important to note that while natural remedies are generally safe and non-toxic, they may not be as effective as other methods, such as ant bait or insecticides. Additionally, natural remedies may need to be reapplied more frequently than other methods. If you have a severe ant infestation, it may be best to consult with a pest control professional for more effective treatment options.
Using Cinnamon or Peppermint Oil to get rid of ants
Cinnamon and peppermint oil are both effective natural remedies for repelling ants. Here’s how they work:
- Cinnamon: Cinnamon has a strong scent that can disrupt the pheromone trails that ants use to communicate with each other. This can make it difficult for ants to find their way to food sources and nesting sites. Additionally, cinnamon contains compounds that are toxic to ants, which can help eliminate ant populations over time. To use cinnamon as an ant repellent, simply sprinkle cinnamon powder around the perimeter of your RV or on ant trails.
- Peppermint oil: Peppermint oil has a strong and pleasant scent that repels ants. When applied around the perimeter of an RV, the strong scent of peppermint oil can disrupt the pheromone trails that ants use to communicate with each other, making it difficult for them to find their way into the RV. To use peppermint oil as an ant repellent, mix a few drops of peppermint oil with water in a spray bottle and spray it around the RV or on ant trails.
It’s important to note that while cinnamon and peppermint oil can be effective at repelling ants, they may not be as effective as other methods, such as ant bait or insecticides. Additionally, these natural remedies may need to be reapplied more frequently than other methods. If you have a severe ant infestation, it may be best to consult with a pest control professional for more effective treatment options.
Do I need to be careful with pets or children around cinnamon or peppermint oil?
Yes, you should be careful when using peppermint or cinnamon around pets or children. While these natural remedies are generally considered safe, they can still cause irritation or allergic reactions in some individuals, particularly if they are ingested or come into contact with sensitive skin.
To avoid any potential risks, it’s important to keep pets and children away from areas where peppermint or cinnamon has been applied. If you’re using peppermint or cinnamon as an ant repellent, it may be best to apply it in areas that are inaccessible to pets and children, such as high shelves or cabinets. Additionally, be sure to store any unused peppermint or cinnamon products out of reach of pets and children.
If you notice any adverse reactions in pets or children after using peppermint or cinnamon, such as skin irritation, vomiting, or respiratory distress, seek medical attention immediately. As with any pest control method, it’s important to use natural remedies safely and according to the label instructions.
Using Diatomaceous earth to get rid of ants
Diatomaceous earth (DE) is a natural powder made from the fossilized remains of diatoms, a type of hard-shelled algae. DE is composed of silica, a mineral that is commonly found in rocks, sand, and soil.
Diatomaceous earth is an effective insecticide because it has a sharp and abrasive texture that can cut through the waxy outer layer of an insect’s exoskeleton, causing it to dry out and die. DE is also effective against ants because it can be ingested by ants, causing damage to their digestive system and leading to their eventual death.
Diatomaceous earth is safe to use around humans and pets because it is non-toxic and does not contain harmful chemicals. However, it is important to use food-grade diatomaceous earth, which has been specially treated to remove impurities and is safe for human and animal consumption.
To use Diatomaceous earth for ant control, you can sprinkle the powder around the perimeter of your RV, paying special attention to entry points and areas where ants are likely to travel. You can also apply the powder directly to ant trails or to areas where ants are nesting. Reapply the powder as needed, as Diatomaceous earth can lose its effectiveness when wet.
It’s important to note that while Diatomaceous earth is an effective natural insecticide, it may take longer to see results compared to chemical insecticides or ant baits. Additionally, Diatomaceous earth can be messy and may need to be cleaned up after use.
Can ants set up a colony inside my RV wall?
I know you may not want to hear this, but, Yes, ants can set up a colony inside the walls of an RV. Ants can enter through small cracks, gaps, or holes in the walls and establish a nest inside the wall voids. Once inside, the ants can build their colony and continue to expand and forage for food and water.
If you suspect that ants have established a colony inside the walls of your RV, it’s important to address the infestation as soon as possible. Ants can cause damage to the RV’s structure and electrical systems, as well as create unsanitary conditions.
To eliminate an ant colony inside the walls of an RV, it may be necessary to use a combination of methods, such as ant bait traps and insecticides. In some cases, it may be necessary to open up the walls to access and treat the colony.
Prevention is key to avoiding ant colonies inside RV walls. Keep the RV clean and free of food debris, and seal off any potential entry points to prevent ants from entering in the first place. Regular inspections and pest control treatments can also help prevent ant colonies from establishing inside the walls of an RV.
Where do I buy ant bait traps for my RV?
Ant bait traps and ant insecticides can be purchased at most hardware stores, home improvement stores, and online retailers. Look for products that are specifically labeled for ants and follow the instructions carefully.
When storing ant bait traps, it’s important to keep them in a cool, dry place, away from direct sunlight and heat. Be sure to keep them out of reach of pets and children, and store them in their original packaging to prevent contamination.
When disposing of ant bait traps, it’s important to follow the label instructions carefully. Some products may be disposable in the regular trash, while others may require special disposal methods.
