Samantha Hedding says she's spent close to $1,000 trying everything from lights to attract them, citronella, and diffusers - but nothing has worked.
"We've got towels under all of our doors; another neighbor has taped her front door shut because we're not sure how they're coming in," said Hedding. "We haven't been able to open our windows in over a month. The weather's been beautiful, and we haven't been able to enjoy any of that. We're just absolutely miserable."
"She wears a long sleeve nightgown, the only thing out is her hands," said Richard Johnson about his wife. "So, she's laying with her hands outside the blanket, right? They come and they bite her in between the fingers."
Johnson and his wife live across the street from Hedding, and say they're also under attack. Johnson says many nights, his wife has a hard time sleeping because of the mosquitoes.
He's even called Vector Control out to his property.
"They come out and they walk around your property and they say 'No, you don't have any standing water," said Johnson. "They go next door; they don't have any standing water. There's no standing water in all the people that live around here. So, where's it coming from?"
El Segundo Mayor Chris Pimentel said the city first noticed an uptick in mosquitos mid-December, but tracking down the different sources has been an ongoing battle. He says while some progress has been made, the far western part of the city, near the Hyperion Water Treatment Plant, continues to see an influx.
"The water treatment plant, I mean they're dealing with 240 million gallons of water every day, so there's a lot of liquid there," said Pimentel. "So, we identified some standing places there, dewatered it, treated it, there's chemistry in there. We went up and down the greenbelt and basically removed and drained as much water as we could there."
Mayor Pimentel says he also lives in the area seeing an influx and after months of testing, there's been no sign of mosquito-borne disease. He says while that's important, he understands it's a cold comfort for residents waking up covered in mosquito bites.
