The hobo spider (Tegenaria agrestis) is a member of the genus of spiders known colloquially as funnel web spiders, but not to be confused with the Australian funnel-web spider. Hobo Spider It is one of a small number of spiders in North America whose bites are generally considered to be medically significant. Individuals construct a funnel-shaped structure of silk sheeting and lie in wait at the small end of the funnel for prey insects to blunder onto their webs. Hobo spiders sometimes build their webs in or around human habitations. This species of spider has a reputation for aggressiveness, due to its poor eyesight. They will normally avoid contact with humans unless accidentally crushed or squeezed. The spider’s venom is strong enough to cause considerable local pain and, possibly, necrosis. In tough cases, a professional company should be consulted with. Reach out to us for pest control services.
Carpenter ant species reside both outdoors and indoors in moist, decaying or hollow wood. They cut “galleries” into the wood grain to provide passageways for movement from section to section of the nest. Certain parts of a house, such as around and under windows, roof eaves, decks and porches, are more likely to be infested by Carpenter Ants because these areas are most vulnerable to moisture. Carpenter Ant As pests Carpenter ants can damage wood used in the construction of buildings. They can leave behind a sawdust-like material called frass that provides clues to their nesting location. Carpenter ant galleries are smooth and very different from termite-damaged areas, which have mud packed into the hollowed-out areas. Control involves application of insecticides in various forms including dusts and liquids. The dusts are injected directly into galleries and voids where the carpenter ants are living. The liquids are applied in areas where foraging ants are likely to pick the material up and, upon returning to the nest the insecticides will kill the rest of the Colony.
The cockroach is consider it to be a pest because it invades where we live, eat and sleep. There are between 4,000 to 7,500 different species of roaches. Of this amount, only one percent are considered to be a pest. Some of the more common species are: German Cockroach Oriental Cockroach-Blatta orientalis American Cockroach-Periplaneta americana Brownbanded Cockroach-Supella longipalpa German cockroach or Blatella germanica They have pathogens or bacteria on their bodies, but none have been known to be transmitted to humans. Their mouths are used for chewing, not biting. Most roaches are nocturnal, that is, they prefer the night and are sensitive to all forms of light except for the red spectrum. They are most active right after dusk and right before dawn. They seem to appear according to a biological clock. This activity may be a response to a genetic defense because light may indicate the presence of humans, their most dangerous predator. They prefer to live in warm, moist places and are more abundant in tropical areas. However, they can live in almost any environment and they have been found in the North and South Poles. Cockroaches are thought to be about 350 million years old, making them [Read the full story …]
