Spider pest Management
You alone caould select the methods that will solve your spider pest problem or your reaction to the problem Unfortunately, there was and always will be spiders. The one of the best solution is to Manage spiders is do not live where you do. It's unrealistic to expect that spiders could be totally eliminated. But one need not live with abundant spiders. If you can not live with your pest spiders, some of the following approaches could reduce their numbers. There are many ways to Manage spiders:
1) New construction: if you are adding a room, building a house, orremodeling, consider treating the wall voids with relatively non-toxic (to humans) boric acid. This material is picked up on the spider's bodyand eaten when the spider grooms itself.
2) Firewood: Spiders seek warmth and shelter in protected placeslike logs, under piles of rocks, bark and other debris. The wood pileis a choice winter residence. Many spiders ride inside on the firewood.Protect outside wood piles with covering. The more debris that falls onthe wood, the more attractive the spiders find it. It isn't advisableto spray the wood pile. Pesticides with enough residual to keep spidersout could be toxic to handle, ant there is no information available onpossible health effects of burning wood treated with pesticides.
3) Exterminators: Professional pest control operators (PCO's) orexterminators will tackle the job for you. There are many approachesused by various companies.
4) Pesticides (outside): Cyfluthrin, bifenthrin, permethrin,tetramethrin or deltamethrin can be applied around the outside ofdoors, window, vents, outdoor stairwells or window wells, foundations,or cracks and openings. Spray only where needed. Be sure that the site,(indoor use, along foundations outside, etc.) is listed on the label.The product should also be labeled for spiders or nuisance pests.
5) Pesticides (inside): an aerosol bomb or fogger will reduce spiders, as well as fleas and other insects that are already present.It will not provide residual control for insect coming in later. Thepesticide also may not penetrate inaccessible areas. Follow labeldirections.
6) Sanitation inside: Stored boxes, piles of magazines and otheritems in basements create ideal hiding places for spiders. Many liveout their lives and die without ever being noticed. The old practice ofspring and fall cleaning is a practical control measure. Vacuum behindand under furniture and book cases, along baseboards and corners and instorage areas.
7) Structural modification: To manage spider entry by keeping doorsand windows screened; by weatherstripping doors so there are noopenings between the bottom of the door and the doorsill; closing gapsaround water pipes under sinks; and sealing cracks and openings in thehouse.
8) Habitat modification: those spiders which are capable of movingindoors are ones which establish their webs in wood piles, junk piles,disused yard furniture or traps, trash bins, outdoor stairwells, windowframes, porch superstructures, brick piles, or ventilation structures.Eliminating or keeping these sites relatively clean will help to keepspider populations low.
