Rover Ants Are on the Move: What Northern California Needs to Know

Invasive pests aren’t new to Northern California, but a newer and more elusive invader has recently emerged: rover ants. While these tiny, fast-moving ants have long caused frustration in Southern California, we’re now starting to see active infestations in our own backyard—particularly in Carmichael, Citrus Heights, and Roseville.

If you’re only familiar with aggressive Argentine ants, rover ants present an entirely different challenge—one that many pest control companies may not be prepared for if they haven’t dealt with them before.

Rover Ants vs. Argentine Ants

Argentine ants are well-known throughout the region for their sheer numbers and persistent trails. While aggressive, they follow predictable paths and respond well to many professional-grade baits and perimeter treatments.

Rover ants, on the other hand, are far more elusive:

• They don’t follow traditional foraging trails.

• They can nest inside your home—behind baseboards, in wall voids, or even electrical outlets.

• They’re highly adaptive and may ignore baits that work on other ant species.

While Argentine ants overwhelm you with their presence, rover ants frustrate you with their unpredictability.

Why Rover Ants Are Tougher to Control

1. Cryptic Nesting Sites

Rover ants don’t nest in obvious locations. They hide in tight, hard-to-reach areas—making them difficult to treat without advanced knowledge of their behavior.

2. Unpredictable Foraging

Unlike Argentine ants, rover ants don’t leave steady trails. They wander erratically, making it harder to trace them back to the colony.

3. Inconsistent Bait Preferences

Rover ants can be picky. They may avoid common baits used in Northern California and require specialized formulations and placement strategies.

4. Indoor and Outdoor Colonies

These ants can thrive inside and outside the home. Once indoors, they’re often active year-round, especially in humid areas like bathrooms, kitchens, and laundry rooms.

5. Limited Awareness in NorCal

Because these ants are newer to the region, many companies may misidentify them or apply outdated treatments meant for other species—leading to recurring infestations.

What You Can Do to Reduce Ant Pressure Around Your Home

While rover ants are tricky, there are simple steps homeowners can take to reduce the risk of infestation:

• Seal cracks and crevices: Especially around windows, doors, plumbing, and baseboards.

• Eliminate excess moisture: Fix leaks, dry damp areas, and reduce standing water.

• Maintain yard cleanliness: Trim bushes and trees away from the structure. Remove leaf litter and mulch buildup.

• Clean frequently: Keep food sealed, wipe down counters, and empty pet bowls overnight.

• Check potted plants and outdoor items: These ants often hitchhike indoors this way.
