Spring Ant Invasions in the White Mountains: Why April Is Prime Time (And What to Do)

Every April, as temperatures start climbing across the White Mountains, homeowners in Show Low, Snowflake, Taylor, and Pinetop-Lakeside start noticing the same thing: ants. In the kitchen, along baseboards, around the back door. What feels like it came out of nowhere actually follows a very predictable pattern — and understanding it is the first step to stopping it.

At Neff Exterminating, we've been treating ant problems across the White Mountains for over 27 years. April is consistently one of our busiest months for pest calls — and ants are almost always at the top of the list.

Why Ants Come Indoors in April

Ants are cold-blooded, which means winter slows them way down. Once soil temperatures begin to warm in spring, ant colonies wake up hungry, rapidly expanding, and actively searching for food and moisture. Here in Arizona's high country, that threshold typically hits in April.

A few factors make spring especially bad for ant activity in the White Mountains:

• Snowmelt and spring moisture saturate the soil, pushing ants upward and toward structures
• Warming interior walls attract colonies looking for heat and nesting sites
• Post-winter food scarcity drives scouts indoors in search of crumbs, grease, and sweets
• Colony expansion means thousands of new worker ants are being produced and sent out to forage

Once a scout finds a food source inside your home, it leaves a chemical trail back to the colony. Within hours, you can go from seeing one or two ants to a full-on trail moving through your kitchen.

Common Ants Found in the White Mountains

Not all ants are the same — and knowing what you're dealing with matters for treatment. The most common species our technicians encounter in the Show Low and Snowflake area include:

Pavement Ants

Small, dark ants that nest under slabs, sidewalks, and foundations. They tend to enter through cracks in concrete and are common in homes with attached garages or patios.

Odorous House Ants

Named for the rotten coconut smell they emit when crushed, these ants are aggressive foragers and extremely common indoors during spring. They're difficult to control with store-bought bait because colonies can have multiple queens.

Carpenter Ants

Larger black or reddish-black ants that don't eat wood — they excavate it to build nests. Carpenter ants in your home can signal a moisture problem and, left untreated, can cause real structural damage. If you're seeing large ants, especially at night, contact us right away.

Fire Ants

Less common at higher elevations but occasionally found at the lower edges of our service area. Their painful stings make them a priority to address quickly, especially in yards where children or pets spend time.

Where Ants Are Getting In

Ants don't need much of an opening. A gap as small as 1/16 of an inch is enough. The most common entry points we see during inspections include:

• Gaps around window and door frames
• Cracks in the foundation or exterior walls
• Where utility lines (pipes, wires, cables) enter the home
• Under doors with worn weatherstripping
• Around plumbing penetrations under sinks
• Through weep holes in brick or block construction

One thing that's common in the White Mountains specifically: wood piles stored against the home. Firewood is practically a staple out here, but stacked wood is one of the most reliable ant habitats around. Keep it at least 20 feet from your foundation if possible.

Why DIY Ant Control Usually Falls Short

It's tempting to grab a can of spray from the hardware store and call it done. And sometimes, that'll knock back what you can see. But here's the problem: you're not addressing the colony.

Most over-the-counter sprays are repellents. They push ants away from a treated area — but they don't eliminate the source. In many cases, spraying without a proper treatment plan actually causes colonies to split and spread, making the problem worse.

Effective ant control requires:

• Correctly identifying the species
• Locating the colony (which is often outside the home)
• Applying the right product in the right locations — including bait that workers carry back to kill the queen
• Treating exterior perimeters to prevent re-entry

Our licensed technicians are trained to do exactly that. We treat the problem at the source, not just the symptoms.

What You Can Do Right Now

While professional treatment is the most reliable solution, there are steps you can take to make your home less attractive to ants this spring:

1. Clean up crumbs and spills immediately — even small food residue is enough to attract scouts
2. Store food in sealed containers — this includes pet food, which is a surprisingly common ant magnet
3. Fix leaky faucets and pipes — moisture is just as attractive as food
4. Seal visible cracks and gaps around windows, doors, and the foundation
5. Move firewood away from the house and keep it elevated off the ground
6. Trim back tree branches and shrubs that touch the exterior — ants use them as highways

These steps help, but if you're already seeing ant activity inside, the colony is likely already established nearby. That's when it's time to call in a professional.
