Control
Eliminating an infestation of brown recluse or black widow spiders involves two basic principles:
1.(1) altering the environment in and around a building to make it less attractive to spiders; and
2.(2) finding and destroying as many spiders as possible.
The following measures can be used to control all spiders:
◾ Routine, thorough house cleaning is the best way to eliminate spiders and discourage their return. A vacuum cleaner or broom effectively removes spiders, webs, and egg sacs.
◾Spiders prefer quiet, undisturbed areas such as closets, garages, basements, and attics. Reducing clutter in these areas makes them less attractive to spiders.
◾Large numbers of spiders often congregate outdoors around the perimeter of structures. Migration indoors can be reduced by moving firewood, building materials, and debris away from the foundation. Shrubs, vines and tree limbs should be clipped back from the side of the building.
◾Install tight-fitting window screens and door sweeps to exclude spiders and other insects. Inspect and clean behind outdoor window shutters.
◾Consider installing yellow or sodium vapor light bulbs at outside entrances. These lights are less attractive than incandescent bulbs to night-flying insects which, in turn, attract spiders.
◾To further reduce spider entry from outside, insecticides can be applied as a "barrier treatment" around the base of the foundation. Pay particular attention to door thresholds, garage and crawl space entrances, including foundation vents. Carbaryl, bendiocarb, chlorpyrifos, or any of the synthetic pyrethroids (e.g., cypermethrin, cyfluthrin, lambda-cyhalothrin) are effective, but may need to be reapplied periodically throughout the summer. Wettable powder or microencapsulated ("slow-release") formulations are most effective.
There are basically two types of electronic pest control devices widely available, these are Ultrasonic and Electromagnetic.
Ultrasonic devices operate through emitting short wavelength, high frequency sound waves that are too high in pitch to be heard by the human ear (all frequencies greater than 20,000 Hz).[dubious – discuss] Humans are unable to hear sounds higher than 20 kHz due to physiological limitations of the cochlea. Some animals such as dogs, bats[citation needed], and rodents can hear well into the ultrasonic range. Some insects, such as grasshoppers and locusts can detect frequencies from 50,000 Hz to 100,000 Hz, and moths and lacewings can detect ultrasound as high as 240,000 Hz produced by insect-hunting bats.
Insects detect sound by special hairs or sensilla located on the antennae (mosquitoes) or genitalia (cockroaches), or by more complicated tympanal organs (grasshoppers, locusts, moths and butterflies).
Electromagnetic pest repelling devices claim to alter the electromagnetic (EM) field of household wiring, and vibrate the electromagnetic field that always exists around the wiring in the walls of your house. This alteration in the EM field is said to affect the nervous system of certain pests such as spiders and ants. This may well be on the scope of pseudo science however there have been similar studies using the same technology such as experiments on the effect of EM frequencies emitted by cellphones on humans.[1]
Radio wave pest control
You can make your own spider repellent to use in your home and garden. There are many natural ingredients you can use that repel spiders that won’t harm you, your family or your pets. Natural spider repellents have to be applied more often than pesticides, but they are safer and they have a pleasant smell. All spiders have their taste buds on the tips of their legs and there are certain scents they hate, so using those scents will repel the spiders, both inside and outside your home.

There's no way in hell I would allow the most poisonous spider known to humans in the world to live that close to my bed while I'm sleeping. If one just happens to be walking around your house when you're sleeping, and crawls up onto your bed, you roll over onto it and BAM get bitten, you're dead if you can't get to the hospital quick enough.
All because you allowed them to survive.
No way
No way
NO WAY! lol
