If you’ve felt like pest activity around your home has been getting worse in recent years, you’re not imagining it. Yelp’s Spring 2026 Infestation Index, which analyzed pest-related searches across the United States from March 2025 through February 2026, put a number on what South Bay residents have been experiencing firsthand. Los Angeles ranked number one in the entire country for pest control search volume. Not second. Not third. First.

For those of us who live and work here, that finding isn’t surprising. But it’s worth understanding what’s driving it, what pests are surging the most and what it means practically for homeowners in Torrance, Redondo Beach, Manhattan Beach and throughout the South Bay.

How the Index Works

Yelp compiled the 2026 Infestation Index by analyzing the volume of pest-related searches on their platform across core-based statistical areas throughout the United States. Cities were ranked based on total search volume and limited to two cities per state to ensure geographic diversity in the results.

The data covers a full year of search behavior from March 2025 through February 2026, which means it reflects real consumer behavior across all seasons rather than a single spike during one particularly bad month. It’s a broad and meaningful snapshot of where pest pressure is genuinely being felt.

Los Angeles at Number One

Los Angeles claiming the top spot ahead of cities like San Francisco at number two, New York at number three, Dallas at four and Phoenix at five says something important about the nature of pest pressure in Southern California.

Most cities with significant pest problems are driven by seasonal surges. Hot humid summers in the South, spring thaws in the Midwest, late summer heat in the Southwest. Los Angeles and the surrounding region, including the South Bay, don’t follow that pattern. Our mild temperatures mean pests stay active year-round. There is no hard winter to kill off populations, no cold season to slow reproduction and no months where pest pressure naturally drops to a manageable baseline.

The result is a city where pest control searches stay elevated across every season because pest activity stays elevated across every season. Homeowners here aren’t just dealing with a summer spike. They’re dealing with consistent pressure twelve months a year and the Yelp data reflects exactly that.

The Pests Driving the Biggest Search Surges

The index also highlighted which specific pests are generating the most dramatic increases in search activity. Three stand out and all three are pests we’ve covered in depth here on the ASPCW blog.

Bees: up 197%

Searches for bee control spiked 197% on Yelp comparing February 2025 to March 2025, making it one of the sharpest single-month jumps in the index. This reflects the natural surge in bee activity that happens as spring arrives and colonies become more active and visible. As we discussed in our article on whether bees are protected in California, bee situations require a thoughtful and informed approach. Not every hive needs to be removed and understanding what you’re dealing with before taking action is always the right first step.

Wasps and hornets: up 212%

Wasp and hornet extermination searches rose 212%, the largest increase of any pest category in the index. This lines up with what we see in the South Bay every spring as wasp colonies that began building in early spring reach a size where homeowners start noticing nest activity near eaves, in wall voids and under decking. Yellow jackets in particular become increasingly aggressive as their colonies grow through the summer and into early fall.

Mosquitoes: up 157%

Requests for mosquito extermination rose 157%, a surge that reflects both the growing presence of the Aedes mosquito species in Southern California and a broader increase in awareness about what professional mosquito control can actually accomplish. As we covered in our article on keeping mosquitoes out of your yard, the Aedes mosquito bites during the day, breeds in very small amounts of standing water and is far more disruptive to daily outdoor life than the evening-biting species most people grew up dealing with.

Why California Leads the Country

Yelp’s report specifically noted California’s mild temperatures as a key factor in the state’s elevated pest activity compared to other parts of the country. This is something we talk about constantly with our customers and it’s worth putting it plainly.

In most of the United States winter functions as a natural pest control mechanism. Cold temperatures kill off large portions of insect and rodent populations, slow reproduction and give homeowners a genuine break from active pest pressure. California, and the South Bay in particular, doesn’t get that break. Our winters are mild enough that ants, cockroaches, spiders and other common pests stay active and reproductive throughout the year. What would be a seasonal problem elsewhere becomes a year-round management challenge here.

This is exactly why recurring pest control service makes so much more sense in the South Bay than a once-a-year or as-needed approach. The environment isn’t giving you the seasonal reset that homeowners in other climates rely on. A maintained barrier is what fills that gap.

What This Means for South Bay Homeowners Right Now

Spring is historically when pest activity begins its annual ramp-up and the Yelp data confirms that Southern California homeowners are already feeling it. The surge in bee, wasp and mosquito searches between February and March 2026 tells us that people are encountering these pests in meaningful numbers and actively looking for solutions.

If you’ve been thinking about getting pest control service set up, or if you’ve been on a plan and wondering whether to stay on it, the data makes a clear case. You are living in the number one pest pressure market in the entire country. The conditions that drive that ranking, mild temperatures, coastal humidity, dense urban landscaping and year-round pest activity, aren’t going anywhere.

The good news is that consistent professional service works. Customers on recurring plans with us deal with far fewer urgent situations because problems are caught and controlled before they have a chance to establish. That’s the practical response to living in the most pest-active metro in the country.

The Full Top 20 for Reference

For context, here is how the full Yelp 2026 Infestation Index top 20 ranked out. Los Angeles, San Francisco, New York, Dallas, Phoenix, Chicago, Washington DC, Houston, Seattle, Miami, Boston, Philadelphia, Atlanta, Tampa, Portland, Charlotte, Honolulu, Denver, Detroit and Las Vegas rounded out the list.

Two California cities in the top two spots. That’s not a coincidence. It’s a reflection of the climate conditions and year-round pest pressure that make professional pest control not just useful but genuinely necessary for homeowners throughout the state.

Frequently Asked Questions

Why did Los Angeles rank number one for pest control searches?

The primary driver is California’s mild climate, which keeps pest populations active year-round rather than experiencing the natural seasonal die-offs that occur in colder climates. Combined with the density of the Los Angeles metro area and the coastal conditions that support mosquito and insect activity, the result is consistent and elevated pest pressure across every season. Yelp’s data reflects what homeowners here are experiencing on the ground.

Are bees, wasps and mosquitoes really that much more active this spring?

The Yelp data suggests yes. Bee control searches spiked 197%, wasp and hornet extermination rose 212% and mosquito extermination requests were up 157% comparing February to March 2026. These are significant single-month increases that align with the natural surge in stinging insect and mosquito activity that happens as spring arrives and temperatures warm.

Does living in the South Bay mean I’ll always have pest problems?

Not always, but it does mean consistent pest pressure is part of the environment you live in. The mild climate that makes the South Bay such a desirable place to live is the same climate that keeps pests active year-round. The practical response is consistent management rather than reactive treatment. Homeowners who stay on a regular service plan deal with far fewer significant pest situations than those who wait until something becomes a visible problem.

What should I do if I’m already seeing increased bee or wasp activity this spring?

Give us a call before taking any action. As we covered in our bee and wasp articles, the approach to stinging insects depends heavily on the species and the location of the nest. Bees in particular deserve a thoughtful assessment before any removal is considered. We can come take a look, identify what you’re dealing with and advise on the right course of action.
