When it comes to spider extermination in Fresno, one of the most common misconceptions people have about is that creating a barrier is the best way to keep spiders away. With spiders long legs they are often able to walk over many types of pest barrier without adverse effects.
A good spider treatment starts with the fence line and moves to the home, making sure to treat the spiders directly. Then all the bushes, lawn and flower beds should be treated. Most companies have stopped including a flea & spider lawn treatment and those that do rarely use an eco-treatment. We do both, making sure to treat spiders where they hide and removing the spiders food (Bugs) source.
There are several spiders we encounter more than any other:

All spiders are not poisonous. In fact, the vast majority are not. However, we do have several varieties of highly toxic spiders in Fresno and the Central Valley.
The most common one is the black widow. They’re an easily identifiable spider with a large black abdomen and red hourglass on the back (pictured). If you notice these spiders in or around your home, its important to call professionals for assistance. The black widow is widely considered the most venomous spider in North America.
While most other spiders are not poisonous, this doesn’t mean they’re fun to have around your home. Regardless of the type of spider, give us a call for a free quote and to schedule an inspection.
It’s a process called ballooning, in which a spider uses the earth electric field and a strand of silk to travel as high as 3 miles in the air and as for as 1,000 miles. Sailors first noticed this in the 1800’s when there boats would be covered in webs, even when they were miles from land.
Black Widow spiders are one of the most venomous spiders, famous for eating their male mates. However, the bite of a black widow spider is almost never fatal to humans.
The webbing of a black widow spider is super sticky and can be found in places that make it easy for it to hide such as the underside of stones, decks, inside trees that have a hollow space in the trunk, etc. Black widow spiders can also grow inside your homes but mostly in dark corners or garages or under the sink etc. The male black widow does not bite, it is the female that is concerning. Humans can resist the bite if they are an adult but children may be very threatened because of it.
Types: The family from which the black widow spider comes, namely Theridiidae, there are known to be about thirty-one species of the spider in the genus however there are five main types listed below;
1. The red widow 2. The brown widow 3. The Western Widow 4. The Southern Widow 5. The Northern Widow
Size: The interesting fact about the size in which the black widow spider can range is that they vary upon the gender. The female black widow spider is known to have a body and abdomen that ranges from twelve to sixteen millimeters whereas upon including the leg span too, the average size increases to thirty-eight millimeters. The male black widow spider ranges about half of the female’s size, might as well be even smaller than that.
The breeding ritual of the black widow spiders is where its name was derived from. The female black widow spider feeds on insects but it also feeds on its male mates. The spider tends to feed on it’s male’s counterparts right after mating thus becoming a widow itself hence, the name black widow. The breeding of the spider is very violent. The process starts when the male spider lays its semen on the web along with his sperm and palpi. Upon inserting his palpus into the female’s opening, the mating begins. The female then lays her eggs in a secured sac. A female black widow spider can lay up to several hundred eggs per sac. The can lay as few as four sacs and as many as nine sacs each year. The process takes twenty days to a month.
In the maturation of the eggs, till they hatch. Around one hundred spiderlings will usually survive as they are known to be cannibals and end up eating the other eggs during the maturation process. The female spiders are larger and live longer than the males.
Black widows are found in California. They can also be found around the globe in Asia, Australia, Africa, as well as South America. They usually reside in dark places where they can easily hide.
Life Cycle: The mating occurs in early spring and by the end of the summer, the female black widow has already laid her eggs. The eggs are protected by the female spider until they hatch into spiderlings.
By the time spring arrives, these babies mature into young spiders. Young spiders are white and orange in color but they turn into shiny black as they grow up. Then during the next process which is called ballooning, the spider becomes able to release the silk web thread into the air and it creates a passage for itself to move to different places. Then they entirely become adults overwinter by hiding and find their own food along with making their own webs.almost
