Cockroaches spread bacteria, parasitic worms and other dangerous pathogens as they crawl through the ground picking up germs on their legs and bodies. They then transfer the germs to food and other surfaces. Recent studies link cockroaches to allergic reactions and even asthma.
German cockroaches are light brown or tan with two parallel stripes on their backs. They are 1/2” – 5/8” in size and oval in shape. They have 6 legs and an antenna.

Ants are social insects, living in large colonies of groups. Depending on the species, single ant colonies can be made up of millions of ants.
There are three kinds of ants in a colony: the queen, the female workers and males. The queen and the males have wings, while workers do not. The queen is the only ant that can lay eggs and spends most of her adult life laying eggs.

There are many families of spiders, all of which are considered predators. Spiders are not classified as insects but belong to a closely related group called arachnids. Spiders are advantageous to the environment because they reduce the overwhelming numbers of insects in gardens and landscapes. Most spiders are harmless to humans but some can be very dangerous. Spiders can enter homes through screens, around windows, doors and cracks. Some of the most common types of spiders found in Maryland are Wolf Spiders, House Spiders, Grass Spiders, Brown Recluse and Black Widow.
Wolf Spiders are 1/2” in size. Their shape is segmented and oval. They are dark gray and brown. They have eight legs and antenna.
Wolf Spiders reside close to ground level and will burrow into the ground if threatened. They are usually found around the home in gardens. They are primarily nocturnal and are quick movers if disturbed.
Their bite is very painful and poisonous but not lethal. They are usually not aggressive but will bite if provoked. Their bite can be dangerous especially to young children and the elderly. The bite may cause symptoms such as vomiting, dizziness, muscle pain and headaches. First Aid should be sought immediately.
House Spiders are 1/2” in size and their shape is segmented and oval. They are dark brown or black and have eight legs and antenna.
House Spiders move rapidly and are usually found near window frames, under eaves, in gutters, sheds, toilets, and around rocks and like to hide in corners. They nest wherever they can attract their prey. House Spiders eat other insects such as mosquitoes, flies and moths. They enter the house in early fall and are active for several months weaving webs in confined spaces.
These spiders can bite humans and cause a small irritating spot, which may not heal for 8 to 10 days. Bites can be dangerous especially to children and the elderly.
Grass Spiders are 3/4” in size with long spinnerets. They are dark gray or brown with stripes. They have eight legs and antenna.
Grass Spiders live and make their webs in tall grassy areas, heavy ground cover and thick shrubbery. Their webs are constructed near ground level around steps, window wells and foundations. Grass Spiders feed on other insects like mosquitoes and flies.
Although their bite is painful, they are not dangerous to humans.
The Brown Recluse Spiders seek out dark, warm, dry environments such as sheds, closets, porches, barns, basements, wood piles, tires and storage areas.
Just like other spiders, the Brown Recluse is shy and non-aggressive but will bite if threatened or with contact against the skin. Most bites occur in the summer months and can be very dangerous even causing death especially for children and the elderly. First Aid should be sought immediately after a bite.
The Black Widow is common in Maryland but rarely found indoors. These spiders are most often found in basement window wells, beneath lawn benches or porches, in garages, tool sheds, old lumber piles, rock piles, trash piles, and water meters.
Black Widows can lay up to 400 eggs at a time and are known to be cannibals, often eating each other. They also feed on beetles, flies, grasshoppers, moths and other spiders. Their webs are thick and unstructured resembling a cobweb.
Black widow bites are very painful. Doctor care should immediately be sought. It is very important to recognize this spider and describe the symptoms accurately so the physician can offer treatment.

They typically live outdoors in rural areas where they seek shelter in hollow logs or debris piles. When they enter the indoors, they usually remain in garages, crawlspaces or attics.
Deer Mice carry a potentially dangerous virus known as Hantavirus Pulmonary Syndrome. The virus is transmitted though their dead carcasses or by inhaling airborne urine droplets of diseased mice.
House Mice are 2” in size and round in shape. They are light brown in color.
They can live indoors or outdoors and can squeeze their bodies through tiny spaces as small as a dime. They are the most common breed of mice in the United States and breed quickly.
House mice carry fleas, lice, mites and ticks, which they then carry into your home. Their droppings contain harmful germs and contaminate food and food surfaces.
Norway Rats reside in wood piles and fields and prefer farmland although they have adapted to a more urban lifestyle and can also be found in sewers and garbage-strewn areas. They can squeeze their bodies though areas as small as a nickel. They feed on trash, seeds, meat, dairy, birdseed and compost.
Norway Rats are very dangerous and can spread harmful parasitic diseases. Their droppings also spread harmful germs and contaminate food and food surfaces.

Roof Rats are the creatures known for spreading the Bubonic Plaque. They spread parasitic diseases and contaminate food and food surfaces.
In fact, mosquitos have been called one of the biggest killers in the world. Mosquitos carry diseases like Malaria West Nile Virus, Encephalitis, Chikungunya, Heartworm (in pets), and Zika Virus just to name a few.
Mosquitos can be found just about anywhere throughout the world and typically breed in standing water. Mosquitos can thrive in any climate until the extreme cold months kill them off. In Maryland, mosquitos season typically starts in late April and extends to September.
