The Yellow Sac Spider can be identified as having a bright green or yellow body with dark feet. This nocturnal nusence spends most of its life indoors (corners, basements, attics) and outdoors (grass, trees, bushes or shrubs). During the daytime they rest in small cocoons that are found in attics, ceilings, or basements. They can build these nesting areas in as little as 10-15 minutes.
Yellow Sac Spiders are surprisingly more aggressive than most Utah arachnids. They are responsible for most of the spider bites that are found when waking up in the morning. The bite is know as Cytotoxic, meaning it causes skin death in small areas where the bite takes place. It can be compared to Hobo or Brown Recluse spider, just not as toxic. The bite will cause a small red bump on the skin.
The months of April-October are the heavy outdoor season and they migrate inside the home the remaining months of the year.
The Utah Plant and Pest Diagnostic Lab surveyed of most frequent identified Arachnids from 1978 to 2010. Here are the results of the findings:

The female spider can lay up to 3,000 spider eggs in one sac. The sac maintains a fairly consistant humidity level to keep the eggs from freezing during extreme winter temperatures. After the female spider lays the eggs, she usually will die afterwards due to the effects of the laying.
Areas where spider egg sacs are most common is in the eaves or in any wood or brick corners. This is where there is a comfortable crevice to safely harness the sac from weather conditions.
The Black Widow spider is approximately (1 1/2 inches) in diameter, including legs. Black Widow spiders are common around wood piles, and are frequently encountered when homeowners carry firewood into the house. They are found under eaves, in boxes, outdoor toilets, meter boxes and other undisturbed places. The female Black Widow occasionally eats the male after mating (hence the name). She hangs belly-upward and rarely leaves the web. The black widow is not aggressive, but it will bite instinctively if you touch it. Black Widow bites are sharp and painful, if you are bit seek medical attention immediately.
Ever wonder what causes the little holes in your backyard? 9 times out of 10 they are holes from Voles (often confused with mice). Mice and rats have large ears, voles, on the other hand, have very small ears. Voles will burrow underground and create a tunnel system near grassy areas.
In the U.S. 23 species of Voles are currently present. Five are common in Utah- the Prairie, Meadow, Long Tailed, Water, and the Montane Vole. This small pest is generally less than 10 inches in length and can usually be distinguished by a brown or gray color. They can be found in areas where they feed, in large patches of grass or heavy foliage areas. Beside eating only vegetation and bark off of trees, they also eat snails and insects. Voles are both nocturnal and diurnal, meaning they live in both the day and night. If you see any holes around your home contact us immediately to get this pest taken care of.
