Does it kill spiders? I am loving what I am reading but no comments about spiders (we seem to have a lot of wood spiders)

Hi, yes it does kill spiders. We had 2 major bug problems and that was with fleas in the back yard and black widows around our garage. It helped tremendously with both. The trick is to lay down a light layer of the earth along the wall creases and corners if you are putting it on the inside of your house. You only want to do a light layer at first because you want them to walk through it, if it's too much they may avoid the area all together. Then after a week you lay down another light layer just to keep it fresh and to catch any stragglers that may still be out. I only dusted the inside of our house around our windows cause that's where they seemed come in at but we mainly used it outside. We dusted our whole back yard with it and then along the sides of the garage. Keep in mind to only lay it in the dry areas outside because if you lay it in an area that's always moist it won't do any good. But again same process, light layer at first, wait a week and then refresh or refresh anytime after it rains. Keep in mind it does take a few days for the bugs to die and they have to have walked through it in the first place but still it is effective. The fleas dropped pretty well after the first layer and as long as we keep up on refreshing the yard with it they are pretty much kept at bay. The spiders took a little longer but I think it's just because they took longer to walk through it. I hope this helps. :)

My understanding is that is kills any type of hard shell bug. The product is made of tiny little shrimp. The reason that is not toxic is because the diatomaceous earth breaks down the hard shell of the bug leaving it unable to be protected by its hard cover. While I have never read anything that says that it kills spiders I would think that it does.

It is suppose to kill exoskeletal bugs which a spider is. Although for it to be effective for your spiders you will have to put it in an area that they will crawl through as it needs to get on their legs/body to be effective. I use it in my chicken coop but only in the bedding...works great on the bugs i am targeting...but i still get a few spiders but they are probably coming in through the windows. Good luck.

That's a tough question! I've caught pretty large spiders but don't really have roaches here. The thing has been pretty damn great though. It would still be worth it for the other bugs if it didn't work for the roaches lol

It works excellent on spiders. I am not sure on the mites, but I know it kills fire ants and anything that kills them I'm sure would kill a mite.

I have them in the garage and around the house. Not in the living room or bedrooms. Its a little quiet clicking noise, but not loud. I had it in the living room, but I kept focusing on it rather then the tv. Maybe because it was new. Probable could eventually tone it out. See a few mice in my detatched garage, but mainly dead ones from the poison tabs I put in there. No mice ever in house. Dont know about other pests it says it gets rid of. Not a lot of spiders everbin our house. Let me know if this helped you or not

Yes it kills pretty much all insects, unfortunately it wipes out bees as well. It's delayed reacting though, don't spray a hornet nest with it lol.

I have never put it in my yard just on plants in my garden. It seems there would be something more economical to use in a yard for tics. I am not even sure it would kill tics since they live off of blood they might not even eat it. It does kill spiders and can be put around a foundation for that purpose. Other than what I have written I don't know anything else.

I didn't see it do anything to spiders however its pretty good with mosquitos. try to apply it at a time were its not gonna rain heavily cause the rain sort of dilutes it.

Delta dust will kill anything that moves, including humans if ingested. For larger pests it may take longer to die. It's a neuro toxin. Our wolf spiders took a while, even with direct contact spray. My pest guy says anything that will "clean itself" will ingest this. This is why bed bugs die, even though they live off of blood. They, like most insects, clean themselves like a cat. Gross!

Yes it will still be effective. This stuff is great. It does NOT kill them like Raid. The bugs crawl or fly away after they land on it. On one of my houses I noticed that spiders actually spun webs and then died. The people who make it are super cool. Just call if you have questions.

I used to have many spider webs spring up, but since I have been using Riddex, I have not had that problem. I have seen one tiny spider, but it seems that Riddex is keeping them away.

No idea i know it wirks well around the house for insects by leaving an invisible layers, so that when self cleani.g insects such as roaches it affects tbere nervous system. I believe if you put it on the meat it may kill them if they land on it if they are slf cleaning. I knlw spiders are a little tricky because they do not clean thwmselves,but from what i understand it kills the beacuse of the trace amounts of insecticide left on other insects they eat so maybe. I would contact a local college science deprtment or the manufacture or just try it. If it doesnt work on the wasps you will have a vreat insecticide for around the house.

My main focus when purchasing them was for the removal of mice-which did not work. I do not recall if I noticed any spiders.

I am not sure about spiders although I have heard it's a natural repellant. I got it to help keep rats out of my outdoor rabbit cage and it works well. I didn't spray it, I put it on cotton pads and put them around the perimeter . Sorry I couldn't be more help. Good luck!

Don't know. Haven't tried it. Did think about it, but the only good spider is a dead spider. It might though, because spiders don't really weigh anything.

This stuff kills everything. I did not have creature alive after I set it off. Stink bugs, ants, spiders were all dead. These were set off in my kitchen and even insects in the upstairs bedrooms with the doors closed were dead.

As far as I know, he hasn't tried that yet. Personally, I believe it would if you are within range. It's worked on every bug he's aimed it at within the proper range. It took me two tries to kill a big spider because I was afraid to get close enough. You have to be within three feet of your target. Good luck!

That is an interesting question..thinking back to last year we did notice some dead spiders on our patio days after spraying. Didn't notice an increase in flying bugs.
