TERRO T2302 Spider, Ant, Roach, and Other Insects Killer Aerosol Spray – 2 Pack

Our house is a spider factory, or so it seems. Spiders and webs n a variety of shapes and sizes on the front porch, back deck, along the downspouts, and in our window wells. And, eventually, in our house! Not any more, thanks to this Terro. I've used it for several years with great success. I spray around the doors and windows, along the downspouts, and in the window wells. Ta-dah! Fewer spiders outside and inside. Great for the garage, too. Keeping a can or two on hand means I'm always ready when a creepy visitor arrives. FYI I try to spray only when we're not going to be outside soon after application and never when my doggie is outside.

IMO this is the best pest defense for your money. The smell is a little stronger, but it works fast.

Shake, shake, shake the can. With that said, it kills Joro spiders very fast. About 60 seconds or so. If used outdoors you may find any slight breeze will reduce the spray's range. Very little is needed to kill the spiders. A half a second spray that makes contact will do. You do NOT need to "marinate" or drown the spider with it. A quick spray and watch.

Works great, killed all the spiders!!

This spray is effective at killing spiders…and just about any other bug. I used it to kill the BIGGEST spider I have ever seen. It required several sprays to incapacitate it, and then a few more to completely kill it. But the gigantic spider died within a few minutes and without me having to touch it, so consider me impressed! Although the bottle is labeled as unscented, it smells absolutely terrible and really bothered my nose, lungs and skin. It must be toxic, so I try not to use it inside or at least vacate the room quickly if I do.
