These "vectors" have been shown to carry a variety of disease-causing organisms. Some of these organisms are the cause of Salmonellosis, Shigellosis, Leptrospirosis, and a variety of other food-borne illnesses. The problem with rodent bait in a food facility is that rodents may carry the poisonous bait in their mouths and drop the bait throughout the facility, contaminating food, food contact surfaces, and food related items.

Mosquitoes are known to have carried diseases such as malaria, yellow fever, dog heartworm, West Nile virus and St. Louis encephalitis. Only in the last century has it been known that mosquitoes are capable of spreading disease. The diseases are often viruses that are picked up by the mosquito when it feeds on an infected host. When the mosquito feeds on another host, it can then spread the disease.

Any insect that feeds on blood can transmit disease organisms from human to human, but mosquitoes are the most formidable transmitters of disease in the animal kingdom. Mosquito-borne diseases are caused by human parasites that enters their blood stream. The female mosquito picks up the parasite when she sucks blood to develop her eggs. The parasites complete a portion of their own life cycles in the mosquito, and either multiply, change in form inside the mosquito, or do both.

Yes, moles rarely but sometimes can be carriers of rabies. Rabies, a virus, progressively paralyzes and can kill any mammal, including humans. Rabies is generally contracted through contact with an infected mole through biting. Though humans should avoid contact with any mole, if a mole seems especially fearless around humans, it could be infected. Call United Wildlife mole control immediately for professional mole removal.

We test freshly killed rodents for diseases but once they are dead, their blood becomes unusable in minutes.

Glesne, Cockroaches are fast enough. They have giant fibers in their ventral nerve cord that transmit the sensory info from their cerci, which sense air currents, directly to their thoracic ganglia which control their leg muscles. This is a reflex circuit which does not need any decision by the cockroach brain. It is fast enough to detect the air wave in front of a predator and allows the cockroach to scuttle away, avoiding capture.

Cockroaches are omnivores, like us. For the most part they will eat anything organic. Mostly they eat dead or immobile things. As indicated elesewhere in the FAQ, they rarely bite a human but might nibble on a sore in the middle of the night when an animal is sleeping. They will eat the glue off the back of postage stamps and the glue bindings off the backs of books, traditional glue being derived from animal protein.

Feral goats carry many parasites such as cestodes, nematodes and protozoans. The degree of cross-infection between feral goats and stock is not known but thought to be fairly low except in well-watered pastures where stocking rates are high. However, feral goats are usually not common in these areas. Feral goats can also carry a wide range of bacterial and viral diseases such as the bacterium that cause melioidosis.

Geese do carry diseases, including swimmer’s itch, histoplasmosis, toxoplasmosis, and giardia. These goose illnesses are spread by contact with goose poop, nest materials and dead geese. When geese live in your pond, swimming pool or nearby lake, parasites that live on the geese will infest the water and climb aboard swimmers, giving them swimmer’s itch. The parasite larvae crawl onto the skin and burrow under it, which leads to a very severe, itchy red rash.

Wild armadillos have been known to be infected with the bacterium that causes leprosy (Hansen's disease). The only cases of transmission from armadillos to humans have occurred in rare incidents in which people ate undercooked armadillo meat.

The main disease problem in foxes is Mange, this cannot be transmitted to humans or cats. In theory fox mange could be caught by dog, but in practice it doesn't. The UK has been completely rabies free for many years and there are well prepared contingency plans for deal with any possible outbreak.

When it is cold, all the stages of the alkali fly life cycle slow down. This means that in warm spots you may see the flies year-round, however throughout most of the lake they are inconspicuous during the winter. Click here for more on the Alkali Fly. top Mono Lake doesn't freeze because it doesn't get cold enough to freeze the salty water. It does get cold enough for fresh water to freeze, however, and at times you can see a thin film of ice floating on top of the lake along the west shore.

I think for good reason, based on ethical intuition, that we are more impressed by the kind-hearted soul who nets the flies to let them out of the house alive versus the person hunting them down for certain chemical death with a bottle raid. Even if our great White Suburban hunter of houseflies uses a fly-swatter for ecological reasons, the more admirable course pertains to the person who uses a butterfly net to simply capture the fly for relocation outside.

We hire commercial flying services to handle our flying. Since 1997 we have used Bluewater Aviation in Silver Falls to handle our commercial flying needs. They are safe, use the best equipment, and know the fly-in business better than most. They are also a licensed maintenance company (Winnipeg River Aircraft).

Liz, The feet of insects including cockroaches are made up of a brush like pile which reacts with a surface like myriad weak suction cups. The weak forces involve adding together thousands of such individual adhering pillus ends and result in a strong enough force to suspend the body of a fly, a roach or even larger non-insectal critters such as lizards. To step the cockroach must remove the pilli individually in a wave, like ripping off some cellophane or an adhesive bandage.

Cockroaches (and most other insects) have two light receptors, one sensitive in the ultraviolet range and one in the green range. Many insects also have a third light receptor peaking in the blue. Most pest cockroaches are not attracted to light. They are active at night and if anything they might avoid light. However, if you have a patio that is lit you might be asking what type of light should you have in your patio lighting scheme.

Laurie, There is a pest cockroach, Periplaneta australasiae, which is common outdoors in the southern USA. It is commonly called the Australian cockroach. It is found worldwide as a pest and also called the greenhouse cockroach because of its predilection for establishing itself as a pest in the warmth of greenhouses at all latitudes. It is also found in western Australia. I am not sure of the etymology of the common name, 'Australian cockroach'.

http://www.bio.umass.edu/biology/kunkel/rolleston/plate_viii.html ... This is an illustration by GEORGE ROLLESTON published in 1870. Cockroaches shred food with their mouthparts and then swallow it using their salivary glands (e) and salivary reservoir (f) to moisten their food before it enters their crop (d).

Cockroaches, like all insects, breathe through a system of tubes called tracheae, a word similar to the name of the tube leading to our lungs. The tracheae of insects are attached to the spiracles which are small valved openings on the side of each body segment, excluding the head. Thus the cockroach can breathe without its head! The valves open when the CO2 level in the insect rises to an unacceptable level; then the CO2 diffuses out of the tracheae to the outside and fresh oxygen diffuses in.

First, few cockroaches die on their backs in the wild. Natural death of cockroaches probably occurs in the stomach of a bird, bat or other small animal. Second, Cockroaches are not used to living on a polished marble or vinyl floor. They are more used to a ruguous living plane including leaves and sticks and other vegetable debris.

I have been told that cockroaches are more resistant to radiation and in a world nuclear war, only the cockroaches would survive. But I have not seen any publication that discusses it with any credibility. I can give only an opinion of my own. I have irradiated cockroaches and constructed killing curves for them using gamma irradiation.

Yes, cockroaches do sleep, if you define it that way. Cockroaches have activity rhythms, i.e. regular times in the day when they are quiet and hide away from the rest of the world as well as wakeful times when they are active, seeking food, water and a mate. The subject of cockroach activity rhythms is well represented in the scientific literature (see my cockroach bibliography). In general, most pest species of cockroaches are active (i.e. awake) during the four hours after lights-out.

Lyme disease – affects humans as well as dogs and rarely cats. In dogs it may cause fever, lethargy, arthritis and occasionally skin disease. Anaplasmosis – rarely diagnosed in the UK but symptoms include fever, reluctance to move and general malaise.Europe Ehrlichiosis – a disease that’s seen in the Mediterranean, signs range from mild fever with loss of appetite to severe illness with anaemia and blood clotting.

Yes. Fleas are a VERY REAL HEALTH HAZARD and are vectors of many diseases. Among these are BUBONIC PLAGUE, SALMONELLA, TAPEWORM, TYPHUS and other FEVERS.

Yes. There are several other viruses circulating among mosquitoes in Ohio that can cause encephalitis. St. Louis Encephalitis, which is closely related to WNV, caused a major epidemic in 1975, resulting in 416 human cases and 29 fatalities. Every year, about 14 Ohioans, primarily children, are affected with La Crosse Encephalitis. In 1991, an outbreak of Eastern Equine Encephalitis affected horses in the Killbuck Marsh area in Holmes and Wayne Counties.
