If you spray your entire yard, won't it deter spiders, which eat insects? Seems like your flying insect count would go up.

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.

This is supposed to help repel and keep spiders away but will not kill them. I sprayed a mixture of peppermint oil, water and a drop of dish soap on curtains, outside foundation, vents, window sills and any visible opening or crack where spiders might get in through. It seems to have helped but I read that it's not permanent and you may have to continue spraying periodically (7-14 days). Try Neem oil, I read neem oil disrupts insects hormonal balance and makes it hard for them to grow and lay eggs. Also, look up organic food grade diatamaceous earth for spiders too. I tried a combination of all of these and have noticed it's helped.

This does not work, especially for insects and spiders. Indoor spiders can be removed with a vacuum. outdoor spiders are good bird food and should be ignored.

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.

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.

I would be cautious as with any insect spray. Don't spray it on your bedding or on clothing. Make sure pets are out of the area (you too) until dry. Remember, it kills spiders it comes into contact with but it also keeps those entering the area from making webs, so the spiders die. I've used it in my basement, and in my storage locker in my apt where I now live.

I think it does attract flies from all of my neighbor's backyards. I wish everyone on the block had one of these. I don't think this is actually a problem because it does trap them very effectively and I do not see any flies other than right at the trap.

I don't spray my plants unless there's a reason for it, only when I detectbugs or fungus on the leaves. Don't overkill and sprayuntil it drips everywhere and as soon as I detect new growth, I leave them alone. I don't use any insecticide or fungicide spray for prevention.

I would imagine so. I caught a small lizard almost immediately after putting it out. Haven't caught anything but bugs since, but I haven't seen anymore lizards near my house, and only one spider since I've set them out.

Only used it on sugar ants, and it was pretty effective. Why kill the spiders; they eat everything else. Of course black widows and brown recluse spiders are in a different category.

It kills them when you first spray. I am not sure about repelling them, for several months I do not have spiders or their webs in windows where I have sprayed and do not see any dead spiders, so maybe it is repelling them.

This poison relies on direct physical contact. If you can spray it somewhere flying insects might consistently land, I think it could be quite effective.

I am not sure exactly what you mean. It will NOT prevent insects from walking over where it is applied, but as you mention, if they come into contact with Demon WP they will die soon after. Depending on the insect, dosage, etc. this can take up to 24 hours I have found. Sometimes I will find a bug inside the house that is disoriented and clearly almost dead. This makes them much easier to kill without making a mess. My experience is that when you first start using it, you will find bugs inside your house either dead or almost dead. After a couple weeks, you will stop noticing so many bugs. This may be because the bugs "learn" and stop trying to invade, or it may simply be that you are significantly reducing their population. Either way, it works GREAT. Some bug problems cannot be solved by Demon WP alone, and require other treatments at the same time. However, I will always incorporate Demon WP as an important element to any termination plan.

I would venture to say that it would, but really do not know. Spiders are on the list of things it kills. It , put a large dent in the outside wood roach population around the deck so I'm guessing it will kill brown recluses too. Joe

I am not sure if it kills black widow spiders with direct contact. I used it for the roach problem that I had at my apartment and it had worked perfectly. Well even though roaches didn't die when I sprayed it directly on them, I did notice an exponential increase in dead roaches in the days followed to no roaches till now. Now not only I don't see any roaches in my apartment, but also not any other bugs. So to answer your question from my experience I'm confident that it will get rid of black widow spiders possibly by both ways of contact.

The product is best used to spray it on surfaces like for spiders, ants etc. I am sure it will affect mosquitoes but only if you are able to blast them while they sit or are flying. I did not purchase it for mosquitoes and for me it would be too costly to use as an aerosol for flying bugs.

I wish I could answer that for you. That moth appears that larger than the tiny moths I was trying to kill. I apologize that I don't know their name but I would not recommend buying large quantities until you know for sure. For me, this product didn't do any good. It didn't even kill aphids. I found out recently that my Lysol All purpose cleaner can drop a house fly right of the air. I would try it, if these moths aren't on plants that you appreciate :) Sorry I couldn't answer you question.
