How Spiders Can Attack and Take Over Your House

There are many benefits that can be attributed to spiders on our environment, and arachnids in the garden will help in keeping the pest insect populations low. Insects that spread diseases like fleas, mosquitoes, and cockroaches are eaten by spiders, and some arachnids even hunt lesser spiders.

Though they don’t pose any structural damage to your house, unlike termites, spiders can quickly breed, populate, and make your home appear unkempt, unseemly, and a dangerous living environment.

A variety of spider species will react differently to methods of extermination, and your house has to be spider-proofed, so they don’t keep entering from outside. The number one concern of having spiders in your living spaces, whether indoors or outdoors is that you may get bitten, resulting in severe health issues.

Spiders don’t usually attack people as a means of seeking nourishment, but many will bite as self-defense or protect their young.

Season changes will attract more spiders into your house from the surroundings as spring turns to autumn into winter. Spiders will breed all through their lives, and mating sees them traveling further afield, leaving many of the resulting offspring making your home a permanent abode.

Recommendations from Pest Management Operatives

Proper sanitation makes your home unfavorable for spiders

Controlling a spider infestation begins with adequate home and surroundings sanitation with an aim to reduce conditions that favor them. This can include simple tasks such as thorough vacuuming to remove spiders, cobwebs, and egg sacs or to deal with their food sources, which are other insects.

Clutter from within your closets, corners, basements, or garages and ground covers against the outer foundations of your house must be cleared.

For interior spaces of your house, preventative measures will include sealing any vents, door, or window spaces that provide spider entry. Potential pathways also include gaps where plumbing pipes, wiring, and cables have been passed into the house.

Anything brought into your home from the yard, storage shed, or garden should be checked to stowaway spiders, including firewood or plants.

Reduced insect infestations drive the hungry spider away

As opposed to the way spiders like to occupy spaces with humans, they luckily don’t eat the food you eat, and cutting off their insect supply is an effective way to discourage their habitation. Spiders eat insects such as house flies, ants, cockroaches, or mites, and eliminating these requires the above-mentioned sanitation or house-proofing methods.

Leftover food, dirty dishes, bread crumbs on the floor, and dirty tables or counters attract insects that appear as a buffet to spiders. This is likely to make them stay and populate within your home, and keeping a clean house will discourage clutter that creates hiding spaces within which to build webs as a means to catch insects or hatch their eggs.

Trap your way to a spider-free home

Setting traps all over your living space not only effectively acts on rodents and cockroaches, but also can help catch spiders. Sticky glue traps are natural, non-toxic, and can be laid in attics, basements, closets, or in your spider-infested outdoor spaces. Traps can, however, be a nuisance in houses where there are pets or toddlers, while they require constant monitoring or replacement.

Clearing the spiders breeding grounds

The surrounding of your house should be made as spider as unfriendly as possible, except for your garden where they help to keep plant harmful pests at bay.

Clutter around the house, such as rocks, compost, and woodpiles, must be cleared while cracks, where spiders can reside, should be caulked. The exterior of your house can be power-washed of any cobwebs, while weather strips or sweeps are used on windows to seal spider entry points.

Vegetation nearest to the perimeter of your home can be shifted further away as this attracts insects and serve as spider hiding spots. Trees, shrubs or climbing ivy along the walls of your house, as well as leaves, mulch or green fences, provide ample hunting ground for spiders.

Blindside spiders with less outdoor lighting

Diminishing the number of insects that make up spider cuisine coming to your home will discourage arachnids from overwhelming your living spaces. Most night-time insects love bright lighting, and spiders will set up camp where your lights, lying in wait for these bugs.

Reducing outdoor lighting, or replacing bulbs with yellow, sodium vapor lights are known to minimize spider infestation as insects migrate to other stronger floodlit areas.

While light sources should be fixed away from doors and windows, insects that spiders love to dine on are more attracted to dark siding houses as opposed to homes with lighter sidings. Yellow sodium vapor bulbs don’t attract spiders since they find them too bright and less appealing to insects that spiders hunt.

Let professionals handle the spider-cides aspects

Due to the safety awareness and knowledge of spiders that pest management solution providers have, its best to have them figure out an effective spider mitigation plan. There are chemical formulations that require the application to spider breeding spaces, while others act as barrier treatments or microencapsulated powders.

Exterminating, controlling, and managing spider investment must not be taken as a quick fix, and pest management professionals have the expertise for this ongoing effort.

Type of Spiders Found both Outside and Inside your Home

Various spider types prefer living in environments that are different from others within the species, as some are attracted to dry while others take to damp places. Common house spiders will spend their entire lives hidden in basements, air vents, crawl spaces, attics, and high ceiling corners,as long as food and water are available.

Spiders generally have a preference for spots that are hidden, quiet, and there’s a lot of clutter, such as garages, storage shed, house eaves, shrubby areas, and within light fixtures.

On the northern hemisphere, the most common types of spiders that you’ll come across within your home include;

  • Common house spider, Parasteatoda tepidariorum
  • The cellar spider, Pholcus phalangioides
  • The wolf spider, Lycosidae
  • The giant house spider, Eratigena duellica
  • The jumping spider, Salticidae
  • The southern house spider, Kukulcania hibernalis
  • The hobo spider, Eratigena agrestis
  • The yellow sac spider, Cheiracanthium mildei
  • The Eastern parson spiders, Herpyllus Ecclesiasticus

Though common spiders aren’t inherently harmful to humans as opposed to other common insects like bees, this creepy crawlies create a nuisance and degrade your house with cobwebs. Spider bites are rare but can prove life-threatening when they happen, giving you one more reason why you should keep spiders out of your living space.

Types of spiders whose bite can send you to the ICU include the hobo spider, yellow sac spider, black widow spider, brown recluse spider, and the eastern parson’s spider.

How to Effectively Get Rid Of the Venomous Types of Spiders

The total elimination of spiders from your indoor or outdoor living spaces can be time-consuming, while using strong chemicals may compromise the health of your household.

Research shows that of more than 3000 spider species in the US, 60% are responsible for a nasty bite, but only half of these are found in your neighborhood, let alone within your living areas.

The two documented spiders that haunt the areas you reside in are the brown recluse and the black widow spider.

According to extensive research done by the University Of Kentucky’s College Of Agriculture Food And Environment, all spiders have poison glands that are attached to fangs. Though only a few types of spiders have venom that is extremely poisonous to humans, they use it alongside excellent sight to either stalk, ambush, or trap insects with their webs.

People with an allergic reaction to spider venom, the elderly and young children are especially susceptible to severe side effects when bitten, and it makes sense to keep a spider-free living environment.

Some spiders, such as the venomous mouse spider, will hunt and consume your small pets, while the poison is detrimental to the health of cats or dogs.
