Bed Bugs take a bite out of San Francisco


SF's Bed Bug Infestation Getting Worse-44% And "hundreds of calls" Worse

Are you ready for a healthy dose of paranoia inducing bug news? Well, here it comes: the bedbug invasion of SF is only getting worse. Invasion, in the US vs. Iraq/Afghanistan sense of the word - the bugs have held a presence here for a long time but the number of troops are growing over the years. In the past couple weeks, there has been quite a surge.

The Public Health Department has seen a 44 percent increase in cases over the past three years. Since bed bugs lay and hatch eggs quicker and more plentiful when it's hot, the recent heat wave has caused a spike in cases. Since the hot weather hit, the Health Department has fielded hundreds of calls about the little beasts.

While most complaints come from single room occupancies (SROs) in the Tenderloin, SoMa and the Mission, the bugs can and do show up everywhere. It was once a common assumption that bedbugs are linked to poverty, but that is not the case. All over the country, they have infiltrated upscale condos, private residencies, movie theaters, and even corporate headquarters like the Penguin Group in Manhattan.

To really get a feel for how widespread this is, check out the National Bed Bug Registry,coincidentally started by a San Franciscan. The San Francisco page shows reports in many different neighborhoods, from the Richmond to Russian Hill.

"It's become an increasingly serious problem in all rental housing in San Francisco," said Sara Shortt, executive director of the Housing Rights Committee of San Francisco. "If it's not treated properly, it becomes explosive, and that's been part of the problem. There wasn't aggressive treatment by landlords."

Bedbugs don't carry diseases but they do leave nasty bite marks on people that are allergic to the numbing agent in their saliva. If you are not allergic, you may be getting bit and don't even know it. For example, this SFBG writer reported last year that it took a while to figure out what was going on when his girlfriend was getting bit every night but he was not.

So, what do we do about it? First, figure out if you have them. Bed bugs only come out for short periods of time and are good at hiding. If you find dark spots (blood or feces), shed skins, eggs, and dead bugs on your mattress, box spring, or linens, you probably have bed bugs. It is recommended that you actually find a bed bug before you start freaking out at your landlord.

Carpenter Ants


Insects Set To Surge, Thanks To Active El Niño Weather Pattern

(NAPSI)-El Niño-the wet- weather pattern blamed for this winter's record snowfall in the East and mudslides in the West-is expected to wreak more havoc this summer with a surge in insects.

Just how bad your pest problem will be depends on several factors, explained Dr. Bob Davis, entomologist and scientist with BASF, the world's largest chemical company. Dr. Davis offered the following pest problem outlook for specific U.S. regions.

The South

With its hot, humid summers and temperate winters, the South offers ideal conditions for a wide range of pests, including many species of ant. Ant populations are expected to grow across the South this year, bolstered by an influx of foreign invaders, including the "Caribbean crazy ant," which had only recently been seen in Texas but has begun to spread to multiple counties in Southeast Texas and may now be in the neighboring state ofLouisiana. The threat of termite infestations could also intensify this summer, with forecasts predicting average temperatures in Florida,Georgia and other surrounding states and above-average to average precipitation.

The West

Colder-than-normal temperatures and heavy precipitation hit many areas of the Western states this past winter. February packed a punch of precipitation and, in March, California officials said the average water content in the Sierra mountains' snowpack had reached 107 percent of normal seasonal levels. One frequent menace is the Western subterranean termite. This native pest can enter structures through cracks less than one-thirty-second of an inch wide, including the tiny openings in concrete slabs, around drainpipes and between the slab and a home's foundation.

The Midwest

States from Missouri to Iowa to Wisconsin saw more flooding last year, with thousands of homes damaged by water. The residual effect this year could be a proliferation of household pests that thrive in damp conditions, such as silverfish and spiders. Moisture also increases the odds for termite invasions, especially in Midwestern states such as MissouriIowaOhio,Indiana and Illinois. In the colder Northern-tier states, carpenter ants are a greater threat to homeowners. Carpenter ants prefer to nest in trees and wood next to homes, but they'll come inside to nest if the opportunity arises.

The Northeast

With record snowfall in the Northeast, wet conditions will likely persist. Combined with the warming temperatures, this will create attractive conditions for a variety of bugs. Common culprits include the Eastern subterranean termite and the black carpenter ant.

Blood-sucking bed bugs on the rise


Cases of bed bug infestations in Lincoln have doubled in the past few years, according to experts.

And it's not just hotels and hospitals that are calling in the experts. Cases of infestation in Lincoln homes

bed bug

 have also rocketed, with more people than ever needing the help of specialist firms to get rid of the nibbling monsters.

Experts say one of the main issues is that bed bugs are very resilient, living not just in mattresses, but furniture, clothing and even between cracks in skirting boards.

Pest control specialist Ian Spraggins from Eradicate Pest Control Specialists, based in Doddinton Park, said: "Bed bugs are most certainly on the increase in Lincoln – we saw a 50 to 55 per cent increase last year and who knows what this year will bring?

"One of the contributing factors is that more people are heading overseas on cut-price holidays where cleanliness might not be given as much attention. All it takes is a few to crawl into a suitcase, be carried back to the UK, then get nice and settled in your own home."

Originally the Norway Rat was called the "Hanover rat" by people linking problems in 18th century England with the House of Hanover (German Royal Dynasty), it is not known for certain why the brown rat is named Rattus norvegicus (Norwegian rat) as it did not originate from Norway.  

Today, we refer to the Norway Rat as the "brown rat" or the "Serwer Rat".


The Norway Rat can be found throughout the United States, all continents and is currently the dominant rat in europe. The Norway rat is most commonly found in urban enviroments and will live anywhere humans live.


This rat is a true omnivore and will eat just about anything, favoring high protiens such as dog and cat food, nuts and even fish. Favorite food items of the Norway Rat include; eggs (cooked), pop-corn, cereal and even macaroni.


Norway rats are well know for damaging and destroying material by gnawing, eats and contaminates stored food, its bite is also a risk to humans as they are a vector or carrier of diseases

The Norway rat is nocturnal and unlike mice they shy away from new objects introduced into their territory. The Norway rats nesting preference is the lower parts of structures such as basements in piles of debris and or merchandise but has also been found outdoors on or around riverbanks, railroad embankments, piles of rubbish and under concrete slabs.


Norway Rats are 7"- 9 1/2" with a tail length of 6"-18" long. Fur is coarse, shaggy and color is usually brown. The Norway rat has a blunt muzzle, small ears and eyes.

Rodents - Calls over rodent problems 'drop' during cold


As Northern Ireland emerges from its sub-zero temperatures, two populations appear not to have fared so well in the big freeze.

An apparent absence of house mice and rats has had a knock-on effect at Belfast City Council.

The council's pest control department has said there has been a decrease in calls over mice and rat problems during December.

Rat The council says calls over rat problems were down in December

The Council's Pest Control Manager, Earl d'Hulst, said both populations may have been hit by a combination of the severe cold and lack of food in some of their habitats including sheds and garages.

The council provides a pest control service to both domestic and commercial rate payers. The council area takes in about 160,000 domestic properties.

Atlanta At Risk For Rats?

WSB News
By : Chris Camp @ October 29, 2009 5:29 AM

(WSB Radio) -- A new report commissioned by one of the nation's largest rodent control companies indicates Atlanta is one of the top cities in the nation at risk for rat infestation.big rat

Rodent researcher Bruce Colvin tells the Atlanta Journal-Constitution "Atlanta's high ranking in the latest evaluation stems from greater urban areas of poverty, a very high foreclosure rate and a much lower city spending on structures and highways."

The d-Con study, which used U.S. Census data on unemployment, foreclosure filings, climate and pest control sales; ranks New York number one, followed by Atlanta, Houston, Louisville, Philadelphia, Chicago, Boston, San Antonio, Milwaukee and Detroit.

More on ladybug swarns!

Seasonal ladybug swarms pester even bug experts

Posted: Oct 21, 2009 02:27 PM PDT

Updated: Oct 21, 2009 08:27 PM PDT

Associated Press Writer

ST. LOUIS (AP) - Pest-control specialist Gene Scholes even gets bugged by them - legions of ladybugs lately swarming his rural Missouri home and other stretches across the country, exploiting gaps in door and window seals for cozier climes inside.

Bug experts say the Asian lady beetles, considered harbingers of good luck in many cultures, are making their seasonal appearance in droves in search of warmth for the approaching winter.

The beetles are harmless to humans. That doesn't make them any less annoying for folks like Scholes.

"Every night when I get home and it's dark, I turn on the lights and I have them to greet me. A lot of them," said Scholes, an entomologist for Reliable Pest Solutions in Quincy, Ill.

Thousands of them have congregated since Sunday outside his home near Hannibal, Mo. Dozens more have weaseled their way inside, he said, "and when they get in my space like that, that's when they bother me."

Their fate? Scholes' vacuum cleaner.

The beetle swarms tend to be heaviest on warm days after a period of cooler weather, Scholes and other insect experts said.

Where the beetles swarm can vary wildly, according to experts. The bugs have been especially thick in recent weeks in parts of Illinois, possibly because of this year's abundance of soybean aphids on which the beetles feasted, said Phil Nixon, a University of Illinois extension entomologist.

"Based on casual observation, many think we haven't had this many Asian lady beetles before," he said.

The beetles are particularly drawn to light-colored buildings with sunny exposures as they look for a warm place where they can ride out the winter. "Basically they just shut down," said Collin Wamsley, an entomologist with the Missouri Department of Agriculture.

The ladybugs aren't venomous but at times bite humans, leaving a red mark as they test a person's fitness as a possible meal. And "people don't like them because they smell bad," the result of their stinky ability to reflexively bleed to ward off birds and other predators, Nixon said.

Some accounts of recent infestations resemble something out of an Alfred Hitchcock film.
