Seed bugs swarm California communities, invade homes, cars

LONE PINE, Calif. -- The gas station's ground was covered with the small, winged bugs. Piles of carcasses, inches deep, sat swept to the sides.

On the road, they rained onto car windshields. They flew by the thousands toward even the smallest sources of light and crept along windows and kitchen tables.

Such has been the skin-crawling reality for the past two months in the high-desert communities at the foot of the Sierra Nevada's eastern slopes, where residents have seen an explosion of the black-and-red seed bug species Melacoryphus lateralis.

"They're in everything. There's no way to get rid of them or eradicate them. They're just here," said Blair Nicodemus, 33, of Lone Pine, while driving with a bug creeping on his windshield. "Sometimes there will be these micro-plumes that'll come through where there will be just thousands of them, and they'll be all over you. ... I'm sure I've eaten at least two dozen, because they get into your food."

Such outbreaks have happened in Arizona's Sonoran desert near Tucson, but scientists say it's the first one they have record of in California.

The influx has been driven by a mild winter and monsoonal weather, which provided healthier vegetation for the nutrient-sucking bugs, said David Haviland, an entomologist with the University of California Cooperative Extension in Kern County.

The bugs' flight into town and toward the lights in homes, businesses or cars, however, might be related to the drying up of native vegetation in the summer heat and the drought, said Nathan Reade, agricultural commissioner for Inyo and Mono counties.

To the north, a different type of bug is infesting the site of the popular Burning Man counterculture festival in Nevada's Black Rock Desert. State officials are working to identify the green, coin-shaped insects swarming the outdoor venue and biting workers setting up for this year's event, which starts Sunday.

Entomologist Jeff Knight, with the Nevada Department of Agriculture, said the bugs aren't bloodsuckers and don't seem to pose a health risk.

In California, the outbreak of fingernail-sized seed bugs is a main topic of conversation in the infested communities.

A printout in a Lone Pine motel lobby warned people to keep their doors shut at night, and a hotel worker advised people to keep their car windows up if lights are on. A Dollar General Store in Inyokern limited its store hours after dark to avoid dealing with the bugs.

Lia Sensanbaugh of Inyokern doesn't turn on her lights at home.

"I've got them real bad," she said. "I've been living off my TV light for about a month and a half."

Gas stations and rest areas along Highway 395 -- a roadway that crosses through sparsely populated and rural areas -- are prime bug targets because of their lights.

After dark, the bugs swirl like surreal artwork below the Pearsonville Shell gas station's overhead lights.

"Millions, tens, twenty, we can't count it," gas station owner Soma Praba said. "At night time, if you go into the station, they'll follow. They go everywhere. They get on your body, your head."

Each morning, Praba's workers have spent three hours sweeping the ground and using a leaf blower to clear away piles of the bugs.

Around eight times a day, workers will sweep, discovering two hours later the same amount of bugs are back, Praba said with frustration.

Spraying insecticide hasn't helped, Praba said, and exterminators have been equally stymied. The bugs also have limited natural enemies: Praying mantises and some spiders or lizards will catch a few.

The only reprieve from the seed bugs seems to be a windy day and the recent smoke from fires.

"We are tired of it," Praba said. "I am waiting for the first snow to come."

At a Lone Pine gas station this week, the side of the building was covered with bugs, and a woman was hosing off the wall, despite the drought, said Kathi Hall, who owns the town's Mount Whitney Restaurant with her husband.
