What’s Bugging Yuba City and Marysville This June
June in the Sacramento Valley means triple-digit days are right around the corner, the rice fields are flooded and green, and pest season is hitting its stride. After a wet spring, we’re seeing some real pressure from several different critters across Yuba City, Marysville, and the surrounding communities of Wheatland, Live Oak, and Gridley. If you haven’t thought about pest prevention yet, now’s the time — because trust us, the bugs have already started thinking about your house.
Here at Green Bones Pest Control, we’ve been running calls all across this area since 2012, and Matt has been doing this work for over 25 years. Every June follows a pattern, and this one is no different. Here’s what we’re seeing right now and what you can do about it.
Why June Is a Critical Month for Pest Activity
Temperatures in Yuba City and Marysville are climbing into the 90s and pushing toward 100°F by mid-June. The spring rainfall we had earlier in the season left soil moisture levels higher than usual, which is great for crops and terrible for keeping pests outside where they belong. As the ground dries out and heats up, insects and rodents start looking for two things: water and cool shelter. Unfortunately, your home offers both.
On top of that, the agricultural activity ramping up across the Sacramento Valley — rice flooding in Sutter and Colusa counties, stone fruit harvest underway, and orchards buzzing with activity around Gridley and Live Oak — all of this displaces pests from the fields and pushes them toward residential areas. It happens every year, like clockwork.
The Top Pests We’re Seeing Right Now
1. Ants — Argentine Ants and Pavement Ants
Ant activity is absolutely exploding this month. Argentine ants in particular are highly motivated right now — when soil temperatures spike and ground moisture drops, entire colonies relocate. They’ll find the tiniest crack in your foundation, follow plumbing lines, and set up shop inside your walls before you know what happened. We’re getting calls about ant invasions from neighborhoods all over Yuba City and down into Wheatland regularly right now.
Watch for: Trails of tiny ants along baseboards, near windows, or around your kitchen sink. Don’t just kill the trail — that won’t fix the colony.
2. Mosquitoes
With the rice fields flooded and standing water sitting in yards, gutters, and low spots throughout the valley, mosquito populations are significant this June. The warm nights we’ve been having are perfect for breeding. This is especially relevant for folks living near the Feather River corridor or on the outskirts of Marysville and Live Oak near agricultural land.
Watch for: Standing water anywhere on your property — bird baths, clogged gutters, plant saucers, even bottle caps. Dump it weekly.
3. Roof Rats and House Mice
Rodents don’t wait for winter. This time of year, as field crops grow tall and thick, rats and mice have plenty of cover — but they’re also actively scouting food and water sources near homes. Once temperatures get brutal, they want inside. We see a big uptick in rodent activity in June and July across the Yuba-Sutter area, especially in older neighborhoods near downtown Marysville and established residential areas of Yuba City.
Watch for: Droppings near appliances, chewed food packaging, or scratching sounds in walls at night.
4. Wasps and Yellow Jackets
Queens that overwintered have been building colonies all spring, and by June those nests are big enough to become a real problem. Paper wasps love eaves, patio covers, and fence rails. Yellow jackets often nest underground, which makes them especially dangerous for kids and pets playing in the yard. We’ve been finding active nests in Gridley and Wheatland neighborhoods in spots homeowners didn’t even know to look.
Watch for: Increased wasp traffic around your roofline, under deck boards, or near wood piles.
5. Earwigs and Silverfish
These moisture-loving insects get pushed indoors as the yard dries out. Earwigs congregate under mulch, debris, and potted plants, and they’ll slip inside through door gaps and weep holes. Silverfish are showing up in bathrooms and laundry rooms more frequently this time of year.
Watch for: Earwigs near exterior doors at night and silverfish darting away when you turn on a bathroom light.
5 Things Yuba City Homeowners Should Do Right Now
- Seal entry points: Check door sweeps, window screens, and any gaps around pipes entering your home. Even a dime-sized gap is an open invitation.
- Eliminate standing water: Walk your property weekly and dump anything holding water. Mosquitoes can breed in a tablespoon of it.
- Pull mulch and debris away from your foundation: Keep a clear zone of at least 12 inches. This removes harborage for earwigs, ants, and rodents.
- Store food and trash properly: Keep outdoor bins sealed and don’t leave pet food out overnight.
- Schedule a preventive treatment: The best time to treat is before you have a full-blown infestation. A perimeter treatment now can save you a lot of headaches in July and August.
Don’t Wait Until It’s a Full Infestation
