This insect gets its name from its silvery, metallic appearance and fish-like shape and movements. Silverfish have no wings, but are able to run very fast. They tend to hide their presence from humans which means any damage they have caused could go unnoticed as well.
Silverfish tend to feed on paper items, glue, clothing and food items, such as flour and rolled oats. Silverfish can live up to a year without food, but require a high humidity environment. They move fast and are typically nocturnal.
Silverfish are found throughout the U.S. and are typically seen in moist, humid areas in the home, such as bathrooms, basements, and attics.
While silverfish are mainly a nuisance pest, they can contaminate food and damage paper goods such as wall paper and books.
Consider a dehumidifier for your home, repair leaky pipes and drains and eliminate or repair any moldy or wet wood. Don’t keep old books and magazines in areas where silverfish are usually found like basements, attics and garages. It’s also important to keep food items such as flour and sugar in tight containers.

Question & Answer

What pest has a boiling-hot response when attacked?


ANSWER: The bombardier beetle can shoot boiling chemicals at its attacker if it feels like it is in danger. The spray is extremely smelly and can reach temperatures of 100 degrees Celsius.



Cockroaches Linked to Increased Asthma and Allergy Attacks

In recognition of National Asthma and Allergy Awareness Month, celebrated in May, the National Pest Management Association (NPMA) is reminding people that cockroaches can trigger bug allergy and asthma attacks, along with other pertinent diseases.

According to the Centers for Disease Control and Prevention, an estimated 25.7 million people, including almost 7.1 million children, have asthma. Many of these cases are caused by one of the most dangerous allergens – cockroaches – that may be crawling inside your home.

“Cockroach droppings, saliva, shed skin and other body parts contain potent allergen proteins known to cause allergic reactions and exacerbate asthma symptoms, especially in children,” said Dr. Jorge Parada, medical spokesperson for the NPMA. “Unfortunately, people who are exposed to these allergens during childhood are at an increased risk for bronchial hyperresponsiveness and asthma problems later in life.”

In addition to being a culprit behind running noses, itchy eyes and wheezing, cockroaches spread nearly 33 kinds of bacteria including E. coli and Salmonella. They pick up germs on the spines of their legs as they crawl through decaying matter, which may be transferred to humans on hard surfaces and through food contamination.

Following tips to prevent cockroach infestations:

Seal cracks and holes around the outside of the home including utility pipes.
Properly ventilate basements and crawl spaces to prevent moisture buildup.
Keep counters free of crumbs and vacuum the floors often to reduce the accumulation of cockroach allergens.
Keep garbage in a sealed container and dispose of it regularly to avoid attracting pests.
Pay extra attention to kitchens and bathrooms – especially under appliances and sinks – as these areas are particularly vulnerable to cockroach infestations.
If you find signs of a cockroach infestation, contact a licensed pest professional to inspect and treat the pest problem.

Long Bodied Cellar Spider

Color: Pale yellow to light brown or gray
Legs: 8
Shape: Long skinny legs with a small body
Size: 1/4-3/8” (6-9mm)
Antennae: False
Region: Found throughout U.S.

Cellar spiders are commonly referred to as “daddy-long-legs” because of their very long, thin legs and as their name implies are found in dark and damp places. There are about 20 species of cellar spiders in the United States and Canada.


Cellar spiders build loose, irregular, tangled webs in corners. They hang upside down on the underside of the web. The webs are not cleaned but instead a new web is continually added. This habit can result in extensive webbing in a relatively short time.


The spiders and their webs are usually found in dark and damp places, such as cellars, basements, and crawl spaces. They can also be found in the corners of garages, sheds, barns, and warehouses, on eaves, windows, and ceilings, and in closets, sink cabinets, and bath-traps. Cellar spiders seem to fare better in areas with higher relative humidity,


Cellar spiders do not pose a threat to humans. While they are commonly found in homes, they usually stay in one place. They are not known to bite. Urban legend has it that their venom is of the most deadly of spiders, but their weak mouthparts keep them from injecting venom into humans. While it is correct that they cannot successfully bite, their venom is not very potent.


Seal cracks on the outside of the home, especially around doors and windows, and use screens to prevent entry into homes. Using yellow light bulbs for exterior lighting may reduce the number of spiders and other insects as they are typically attracted to white-light sources. Additionally, lowering the humidity in basements, cellars and crawl spaces with the use of a dehumidifier or ventilation can discourage cellar spiders from living there.


Merchant Grain Beetles


Merchant grain beetles are typically not found in grain products, but instead like to attack cereals, cake mixes, macaroni, cookies and chocolate. Merchant grain beetles are dark brown and have six saw-like teeth on each side of their bodies. They can grow to be one-eighth of an inch long and have very flat bodies.

Color: Brown, Shape: Narrow Oval, Size:1/10, Legs: Six, Antenna: Yes & Flying: Can Fly and Drawn to light.

The merchant grain beetle’s body shape allows it to crawl into packaging to eat, live and place eggs.

Merchant grain beetles are found in pantries or in food processing areas or warehouses.

Merchant grain beetles can infest stored food products and can contaminate food.

Discard infested packages. Clean spilled grain and food sources.



House Spiders

COLOR: Yellowish brown, abdomen dirty white with a few dark spots (sometimes with a black triangular spot in the center) to almost black, with several dark stripes meeting at angle above tip of abdomen; legs
SHAPE: Elongated abdomen
SIZE: 3/16 – 5/16“ (female) 1/8 – 3/16” (male)

This is usually the spider most often encountered indoors. It is a nuisance pest, probably more because of its webs than the spider itself. This spider is found worldwide and is common throughout the United States and Canada.
The house spider randomly selects its web sites and creates a tangled web. If a web does not yield prey it is abandoned, another site is selected, and a new web is built. Survival is low in modern homes with low humidity and few insects, higher in garages, sheds, barns, warehouses, etc. because of more prey and generally higher humidity, and highest outdoors in protected places.
Inside structures, house spiders are most likely to be found in upper corners, under furniture, in closets, angles of window frames, basements, garages, and crawl spaces. Outside they are often around windows and under eaves especially near light sources which attract prey.
House spiders are nuisance pests but pose no threats to humans.
Seal cracks and use screens on windows and doors. Use a vacuum to remove adults, egg sacs and webs. If a broom is used, adults usually escape.
