Who would have thought your peaceful backyard retreat could double as a tiny ant colony’s picnic spot? Welcome to part 3 of the "Who Would Have Thought?!" series by Portable Spas New Zealand, where we tackle the unexpected challenges of spa ownership. Previously, we uncovered how rodents can wreak havoc on control units. In this instalment, we dig into why ants find your portable spa irresistible and, more importantly, how to keep your MSpa pest-free.
Why Are Ants Attracted to Portable Spas?
Ants are highly resourceful creatures, always on the search for food, water, and shelter. Your portable spa ticks many of these boxes, making it an unexpected attraction for these tiny invaders. Here are some reasons why spa pools in New Zealand often become an ant favourite:
- Warmth and Moisture: The humid environment around your MSpa creates an ideal habitat for ants, especially during colder months when they’re seeking warmth.
- Residual Water or Debris: Even small droplets or leftover particles of food from spa-side snacking can attract ants.
- Secluded Spaces: The crevices and gaps in control units or spa skirts provide perfect nesting sites for a colony.
Understanding these attractants is the first step to ensuring that your backyard oasis doesn’t turn into an ant colony’s new home.

The Risks of Ant Infestations in Your Spa
An ant infestation might seem like a minor inconvenience, but these little critters can cause significant problems for your spa:
- Damage to the Control Unit: Ants are notorious for finding their way into electrical components, which can short-circuit your control unit—a costly repair that isn’t covered under warranty.
- Clogged Filters and Pipes: Ants and their debris can block your spa’s filtration system, reducing efficiency and potentially causing flow errors.
- Contaminated Water: Ant activity can lead to bacterial contamination, making your spa unhygienic and unsafe to use.
By taking preventative measures, you can avoid these risks and keep your spa in pristine condition.
Effective Ways to Keep Ants Out of Your MSpa
1. Maintain a Clean Spa Area
Ants are drawn to food and drink residues, so make it a habit to tidy up after spa-side snacks. Regularly sweep or clean the area around your spa to remove crumbs, spills, or any other residues.
2. Seal Entry Points
Inspect your MSpa and its surroundings for any gaps, cracks, or openings where ants might enter. Use silicone sealant or mesh to close off these access points, particularly around the control unit.
3. Set Up Ant Deterrents
- Place natural repellents, such as cinnamon or peppermint oil, around the spa area; ants despise these scents.
- For more persistent infestations, consider bait stations or ant traps positioned strategically away from the spa itself.
4. Regular Maintenance of Your MSpa
- Clean your inlet and outlet valves weekly to prevent debris build-up that might attract ants.
- Check the control unit frequently for early signs of ant activity, such as live ants or trails leading to the spa.
- Flush your spa’s control pipes periodically to ensure that no blockages develop from insect debris.
5. Store Chemicals Safely
Keep your spa chemicals tightly sealed and stored away. Ants may be attracted to certain scents in improperly stored chemicals.
6. Consider the Surrounding Environment
- Keep nearby plants, bushes, or trees trimmed back to reduce nesting and hiding spots for ants.
- Remove any standing water sources, as these can also be a magnet for pests.
What to Do If Ants Have Already Invaded
If you suspect an infestation, act quickly:
- Disconnect the Power: To prevent damage or hazards, disconnect your spa from power before inspection.
- Inspect the Control Unit: Carefully open the control unit and look for signs of ants or nests. Remove visible ants and clean the area.
- Flush and Clean: Flush your spa’s pipes and clean the filters to ensure no debris is clogging the system.
- Contact the Experts: If significant damage is suspected, email our team at service@portablespas.co.nz for professional advice or repairs.
