The Amazing Spider Brain!

Spiders are extraordinary creatures. Spiderman is perhaps the most well known demonstration of what spiders are capable of.  And just like Peter Parker, spiders are not only phyiscally extraordianry but are mentally adept as well. The spider may be small and unassuming but its brain, like spider man, is nothing short of amazing.

With just apoppy-seed-sized head, spiders employ sophisticated hunting methods. They can successfully navigate their way out of complicated labyrinths, and some have developed a mating dance that takes the breath away from their fellow spiders. Elaborate decorations on the male’s abdomens come in bright fluorescent colors, with patterns that look like human faces and other artistic designs.  Truly amazing. But the whole spider is only about five millimeters long.  What is truly and even more amazing is a central nervous system that allows the male to raise and shake its colorful banner on command, and raise its third legs, in a complex mating display that could last an hour.

Mating is just one behavior controlled by a spider’s brain. The brain is aslo responsible for engaging all its senses, knowing how to hunt and find food and knowing how to operate its eight legs in a coordinated way.

Another amazing feature is their sophisticated visual systems. Jumping spiders have eight eyes. Mutiple eyes gives them a 360 degree (nearly) panoramic view in addition to two front-facing eyes that are as acute as as human’s. This visual combination allows these spiders to pursue and pounce on prey in the same way that cats do. The question that has been puzzzling scientists is how the spider brain actually processes the visual information.

Cornell biologist Ronald Hoy is one of the first scientists to look inside a live spider’s brain with a tiny electrode. He noted tha the organization of the spider brain is similar to any other brain. “If you look at a section of spider brain you’ll find that there are clusters of cell bodies with a cabling of the axons going from one part to another part and that’strue of insects and that’s true of us too,” Hoy says. “Things are just more compact in a spider’s brain because you’re packing a normal head brain into the thoracic ganglion.”

Creepy Crawlies That Give Homeowners A Scare This Halloween

While it’s normal to see bats, spiders and other creatures invade your front doorstep on Halloween in the form of trick-or-treaters or spooky décor, Hulett Environmental Services advises people to be on the lookout for real-life ghoulish pests this fall.

Halloween is a fun celebration of all things creepy and crawly, but it also serves as a reminder that actual pest infestations can cause quite the fright. The spirit of this spooky holiday, we are reminding homeowners to take preventative measures to keep pests from taking up residence indoors.

Here’s a guide to some common critters that may spook homeowners this fall, along with tips to prevent them from turning the home into a haunted house.

Rats – One of the most reviled pests, rats can contaminate food, spread dangerous diseases and create fire hazards by chewing through electrical wires. Before homeowners bring boxes of pumpkins and faux cobwebs inside to decorate for Halloween, they should inspect them for signs of an infestation such as gnaw marks and rodent droppings.

Spiders – Some species of spiders, mainly the brown recluse and black widow, can administer a painful bite when disturbed. Homeowners can avoid coming in contact with spiders by wearing heavy gloves when moving items that have been stored for a long period of time and shaking out shoes before wearing them.

Bed bugs – Bed bugs are similar to vampires in that they feed off of human blood, typically at night. These elusive pests do not transmit disease, but they can leave red, itchy welts on the skin. Before dressing up in a costume that came from a rental or second-hand store, make sure to inspect it for bed bugs.

Hulett Environmental Services offers some additional tips to prevent a pest infestation this Halloween season:

  • Seal cracks and crevices around the home’s exterior using caulk and steel wool. Pay close attention to where utility pipes enter the structure.
  • Keep basements, attics and crawl spaces well ventilated and dry.
  • Keep kitchen counters clean, store food in airtight containers and dispose of garbage regularly in sealed receptacles.
  • Store fire wood at least 20 feet away from the house and keep shrubbery well trimmed.
  • If you see signs of an infestation in your home, contact a licensed pest professional.

Prevent Spiders

Hulett Environmental Services reminds homeowners that there are several ways to prevent spider bites and keep them out of the house all together:

  • Install screens and weather stripping on windows and door sweeps on doors.
  • Fix any cracks in siding and walls, especially where pipes or wires enter the home.
  • Store clothing and shoes inside plastic containers, and shake out all clothing that has been in a hamper, on the floor or in storage before wearing.
  • Wear heavy gloves when moving items that have been stored for a long period of time.
  • Inspect shoes before wearing them, as spiders often hide inside.
  • Reduce clutter in basements, garages and attics.
  • Store firewood at least 20 feet away from the house.

What to do if a spider bites you

What To Do

  • If you suspect a spider has bitten you, try to bring it with you to the doctor so they can determine the best course of treatment based on the species.
  • Clean the site of the spider bite well with soap and water.
  • Apply a cool compress over the spider bite location (using a cloth dampened with cold water or filled with ice).
  • If you suspect the bite is form a black widow or brown recluse spider, and the bite is on an extremity, elevate it.
  • Consider tying a snug bandage above the bite and elevate the limb to help slow or halt the venom’s spread. Ensure that the bandage is not so tight that it cuts off circulation in your arm or leg.
  • Adults can take aspirin or acetaminophen and antihistamines to relieve minor signs and symptoms (but use caution when giving aspirin to children or teenagers).
  • Seek medical attention for any severe signs and symptoms, or if signs and symptoms continue to worsen for more than 24 hours.
