Spiders

Myths and a few fatal poisonings have made many persons afraid of spiders. Others may be annoyed by their habit of building webs across doorways, in corners, on furniture and in other places.

Unpopular as they are, most spiders are shy and harmless to humans. Most have fangs too small or weak to puncture human skin. They usually will not attempt to bite unless accidentally trapped or held. Most are quite beneficial by feeding on harmful insects (flies, crickets, etc.) and mites in and around the home, yard, garden and field. If you are in an area that has heavy populations of dangerous spiders, then some control will be warranted.

Spider Control Challenges

Many circumstances render spiders difficult to control.  They may on occasion make little contact with treated surfaces, sometimes avoiding or absorbing a lethal dose of an insecticide.  And passive hunters such as black widows, remain in their webs, away from any treated surfaces.

Where should I treat for best results?

On the structure:  If possible, apply treatments to likely harborage sites, paying careful attention to areas of web building. This may include, under or around gutters, gaps in the seams of siding, around window frames, shutters, overhanging eves, porches, decks, or fireplace transitions.

Off the structure:  walls, debris, or any other area where spiders may harbor.

 

 

Mechanical control measures can be very effective for immediate and long term control. What we mean by “mechanical control” is simply locating spiders and webs and physically destroying them. Use the Cob Web Duster for brushing out spiders and their webs. By regularly removing old webbing, you can easily determine new activity, and it also removes their food sources in the webs making their environment uninhabitable.

 

 

 

 

 

 

In addition to sanitation measures, utilize the incorporation of glue board spider traps for the capture and elimination of foraging spiders. Trapper Max Glue Boards are sold in packages of 72. Set them out in dark areas where spiders might be hiding or foraging. Maintaining sticky traps behind furniture, to either side of exterior doors, and in the garage is an excellent way to intercept most spiders as they enter.

 

 

 

Treat with a residual insecticide such as Talstar, Tempo, or Suspend, around the foundation of the structure, window frames, door frames, soffit areas, vent openings, exhaust areas, garages, basements, mounted lights, air conditioning areas, cable entry points, deck areas, stoop and patio areas.

Using Drione or Delta Dust in the attic area would be a good measure if there is an infestation in that area. Or you can apply Delta Dust to your crawl space, as it is moisture proof.
