Spiders.There are about 40,000 species of spiders. Spiders are found worldwide, except for in the oceans, and they live in all habitats and at most elevations. Spiders have a different body structure than insects. The bodies of spiders divide into two parts (a fused head and thorax and an abdomen), and spiders have eight legs and eight eyes; they lack antennae and wings. All spiders are carnivorous and eat insects. Some spiders like moisture and are found in basements, crawl spaces and other damp parts of buildings. Others like dry, warm areas such as subfloor air vents, upper corners of rooms and attics. They like to hide in dark areas.
Mosquitoes are distinctive from flies because of their long stinger and scales on the back and veings of their wings. They are found in the tropics to the arctic and are reliant on water as a source.
The Brown Dog Tick is not only a pest of dogs, but, very often, is an unbearable nuisance in the home. Adult ticks can be found in the ears and between the toes of dogs. The female will lay from a few hundred to more than 5,000 eggs in cracks and crevices, carpeting, beneath baseboards, and beneath loose or cracking wall coverings.
