Best for Spiders

Wednesday August 8, 2012


Mr Pest Control


Spiders have been REALLY BAD here this year and I have been getting a whole lot of complaints about them. I have switched products to Temprid and Tempo Ultra and have been dusting weepholes, under decks/patios, and any other place I can see spider webs. What, in your opinion, is the best product for controlling these SOB's? If you have any other suggestions, I'm all ears.

I'll be honest with you Jeremy and say that pyrethroids like Tempo and Temprid have always been the superior materials for spiders. This would also include other pyrethroid active ingredients such as permethrin, cypermethrin, deltamethrin, etc. They have, since Demon TC first started its use on spiders about 25 years ago, just knocked these difficult pests down quickly and with some lengthy residual effect. Some of the new chemistries other than pyrethroids will likely show great spider control as well, but the pyrethroids should continue to be good choices. 

You should talk about spiders and their biology with your customers, and perhaps suggest managing exterior lights as well as possible. Where the lights can simply be shut off at night this will really help keep night-flying bugs away from porches, and spiders have figured out that if they too hang around the lights there will be plenty of other bugs to eat, so one manages the other. You also, if you are not already, could be using a Webster duster each visit for a quick walk around the home to remove spider webs. This could possibly be an add-on service for a few dollars more, but with the persistent webs gone the customer no longer perceives the spiders to still be there. 

But, living things go in cycles too, and more spiders this year suggests that there must be more of their own food available. The heat this summer, nationwide, seems to be higher than usual, and from all the news reports this has translated to more bugs in general. It may have nothing to do with what you are using and how as much as it does to just more spider pressures. There also are a few spider web materials, like Web Away or Cobweb Eliminator, that are advertised to not only remove the existing webs when you spray them but to discourage spiders from building new webs on that treated surface. Supposedly it somehow makes it difficult for the web-spinning spiders to attach the webs to the surface.
