OK ATOT what is the best bug spray to kill spiders?

[CrackRabbit]

So last night I go to put the garbage cans on the curb and much to my surprise there was a black widow that was happily living in between them. D:
After trying to kill it and another that I found living near by with ant and roach spray and several other household chemicals to little avail,
I need to know what will kill them very dead and make sure they don't come back, before my house ends up looking like something out of 'Arachnophobia'.

Hairspray and a lighter?

Had lot of trouble finding this stuff in Canada, because it's probably illegal. Works really well. It does not kill them on contact but it leaves a residual that kills most bugs over time. You spray your whole house with it (preferably outside but it's considered safe for indoor use with some precautions). I used to have tons of spiders in my house and I have a phobia of spider webs, the spiders don't really bother me but it's the spider webs that do. So I wanted something to kill the source. Not only does it kill the spiders, but it kills whatever food they might be feeding on. This stuff will even kill bed bugs apparently.


Anything else that has Lamda-Cyhalothrin as the active ingredient will work well.

This is the answer to all your spider and bug problems. They clean up EVERYTHING and eat each other when the bugs are gone. Pretty soon you'll just have "Bubba" left and as long as you give him your lunch money, everything's copacetic.

This isn't something you need to worry about. You fired the first salvo last night. The spiders will respond in turn tonight. You may want to consider not sleeping tonight - a black widow's favored mode of revenge is to crawl into the open mouth, nose, and/or ears of its intended victim, biting from the inside.

If you do happen to fall asleep tonight, please try to be aware of any tickling or other odd sensations in or on your face.

That sounds like exactly what I need, now to see if I can find it locally.

There is only one solution, I must strike again before sundown.
None shall live to see dawn tomorrow.

Lamda-Cyhalothrin is a damn good chemical.

Also, something with cypermethrin works well. Both chemicals are 2nd generation pyrethroids and work fantastic. Demon is a common brand of cyphermethrin.

More importantly than brand is the concentration of the chemical, either in solution in ready to use containers or after mixing in concentrates. To get an idea about the best, find the ready to use version of whatever brand, and check the concentration there.

Also, wear gloves and long clothes while you spread the stuff. While its not especially toxic to mammals (you have to chug it basically), it can irritate the skin. New evidence also suggests that getting the wet stuff on you/inhaling it could be carcinogenic. Don't let your kids or pets around it before it has dried (inside or outside) and when I use it inside, I usually like to air the place out for a couple hours. You don't need to, but some sprays can be chemically smelling (other ingredients?).

Also, they say the chemicals can last several months. Most are only effective for about 3 months inside, and 1 month outside. If you're getting a concentrate, buy a sprayer. It will make your life so much easier.

Do you really think Amazon is the only source on the planet? Check your local nursery.

WD40 works better.

Nobody buys anything outside of Amazon. :biggrin:

What would be, in general, a good concentration of the Lamda-Cyhalothrin to use? So far I've only found one OTC product that has it and it has a .03% concentration to it.

Edit: NM looks like most products use a .03 to .06% concentration of Lamda-Cyhalothrin.

I don't know why you'd use a spray. Just crush the spider with your shoe or a stick or something.

Not everyone can stand around 24/7 waiting for spiders to come in. A residual spray does all the work, and all you have to do is get rid of the carcases.

According to an experiment I made it takes a day or two for a spider to die from the stuff I suggested. It basically just dries right up. Go to pick it up and it breaks.

Yeah, .03% is the usual concentration for spiders. I'm not familiar with black widows (not to many up here in New England). For hardier insects (such as roaches) concentrations can go to .06% to .08 or .09% for exterior applications. Though you're not supposed to use a "high" concentration unless you have licensing for it (in most states)

If you want a contact spray, just use soap. It sounds too simple but it works, just use some dish soap + water in a spray bottle. It works for all insects incl ants/roaches. I found out that mr muscle could take down houseflies in mid flight after a few shots. Depending on the brands/ingredients, the KO ability will vary but they all work easily on slow moving insects like spiders.
