Spider Sightings Increase in Fall Months

Spider Sightings Increase in Fall Months | Phoenix Spider Control Experts

Spiders aren’t a seasonal pest, but many homeowners tend to notice an increased presence in their homes in the early fall months as the arachnids become more obvious while they search for a mate. Even though most spider species in the United States don’t pose health risks to humans, most people aren’t comfortable with any species sharing their living space. Magic Pest Control reminds homeowners that the best way to prevent spider infestations is to remove harborage sites within their homes.

Spiders seek out secluded, undisturbed areas where they can build a web to catch their next meal, which means attics, basements and seldom used closets could be harboring these pests. Spiders can also crawl into homes through damaged window screens or cracks in the siding, meaning homeowners should conduct periodic checks of these areas to reduce spider problems.

It’s important to note that the black widow and brown recluse spiders are two species found in the United States that do pose health risks to humans when disturbed or feeling threatened.

The brown recluse spider typically does not bite humans unless threatened, but their bites can be painful and result in open sores. Measuring about a half inch with a dark brown violin marking on its back, brown recluse spiders build their webs in warm, dry and dark environments, notably basements and closets. Similarly, black widow spiders do not bite humans instinctively. However, when they do bite, they can cause extremely painful bites, especially for children and the elderly. Recognized for its red hourglass shape under the abdomen, these spiders spin their webs close to the ground and are most often found in woodpiles and undisturbed areas.

Magic Pest Control offers the following tips to help prevent contact with spiders:

  • Avoid keeping clothing and shoes on the floor, especially if in an area known for spiders; consider storing inside plastic containers.
  • Seal cracks and crevices around the home.
  • Vacuum/sweep away webs in and around the home.
  • Shake out all clothing that has been in the laundry basket before wearing/washing.
  • Keep garages, attics and basements clean and clutter free.
  • If a spider bites you, contact your primary care physician for medical advice.
  • If you have an infestation in your home, contact a licensed pest control professional to inspect and treat the pest problem.

Why Researchers Are Fascinated With The Spider Species That Eats Only Termites

Why Researchers Are Fascinated With The Spider Species That Eats Only Termites

Animal Predators can be either picky or indiscriminate when it comes to their feeding choices. There does not exist any predators that can eat just anything, as every predator species has its own tastes. Researchers have also never discovered any predatory animals that only consume one single species, except for one. Recently researchers discovered the very first monophagous true predator, which is a predator that consumes only one particular species of animal. The predator in question is a type of spider that belongs to the Ammoxenidae genus. Researchers have demonstrated that at least one spider species in the Ammoxenidae family preys upon, and consumes only one termite species. This termite species is known as Hodotermes mossambicus.

The Hodotermes mossambicus species of termite is more commonly referred to as the harvester termite, and they can be highly destructive to grassland and other forms of vegetation. Ammoxenid spiders live both in and out of soil and they are sometimes called sand divers due to their ability to dive headfirst into the ground when threatened. Since these termites and spiders both inhabit South African soil, they naturally encounter each other often, and these encounters never end well for the harvester termites. The spiders are always found to be concentrated in regions that are also highly populated with harvester termites, as the harvesters are their only food source. Ammoxenid spiders are able to detect termites either through vibrations or chemical cues. Once a young Ammoxenid spider is given its first harvester termite prey, the spider picks up on tactile cues from this initial encounter in order to locate more harvester termites on its own in the future.

The spider will first attack a harvester by biting one in between its head and cephalothorax. The harvester is then pulled beneath the soil’s surface where it is sucked of all its innards. Since harvester termites are not active year round, the spiders must collect enough harvester prey to keep on reserve during the termites off season. The spiders collect extra harvester termites by placing them in silken sacs for later consumption. The Ammoxenid spiders and their silken sacs are often found habitating abandoned harvester termite mounds.

Do you think that there are more spiders or insects that prey upon one particular species, but scientist have yet to discover them?
