Can this kill Roaches, black widows, and grasshoppers.

Roaches yes, spiders yes, although it doesn't call out specific species. It does not say grasshoppers but It does say crickets. Toxic to fish and cats! I have used for spiders and ants and it works well. Here is a link to a PDF file for treatment and specific insects. http://www.doyourownpestcontrol.com/SPEC/LABELS/PermethrinSFR_Label.pdf

I use it to spray the exterior of my house and outdoor buildings, it seems to keep things from coming indoor, also spray around the grill area.

Hi, I don't know. I only used it for silver fish and small beetles. To be honest, it doesn't really do a good job of killing bugs, but it does slow them down enough to catch them. I like this product because it is non-toxic. It's good enough.

It does a really good job with cockroaches. That is why we use it. My son used it for an infestation of german cockroaches, but then he had to call in a professional to get rid of them.

yes does seem to work well killing spiders, we bought our house in the country last year we had black widows, treated everywhere took care of them.

I don't know about roaches. I've only used it for yellowjackets and those littlte ants that come in from the foundation of the house. Hope that helps.

i think it is a great bug killer, and would kill any kind of bug. it sure got rid of the stinging scorpions around my house. it keeps killing after you spray it on the floor for months.

I've used it in my garage and in the hobby room on my property and to my knowledge it kills just about anything. I've been using it for the past two decades. I find dead roaches, crickets, spiders (you name it) in both buildings after using it. In my garage, I used 3 cans and it is a standard 2 car garage. Same size with the hobby room. I spread the cans out to make sure the building gets full coverage. Usually one treatment a year is enough to keep the building clear of bugs until the next treatment session.

This product is used to kill insects in your home and garden. It is not for human consumption.

I don't think it would be very effective unless you find where they are coming from. I spray ant & roach killer in the area where I see Them. We spray around the baseboards and the outside of the house about every month when they are active. But even the professionals have a problem finding a permanent solution. But the Ant-Zap is amazing.

I am not aware of it killing fleas because fleas live on sucking blood versus roaches eat everything and clean it off their legs and die.

It worked. I used it on yellow jackets, wasps, carpenter bees, and carpenter ants. Killed 'em dead, though not instantly. I find a 2-5 minute delay from spray to dead. You do have to spray in on the target insect, though.

Yes, it kills everything but it's not an instant kill. It dries invisibly & the insects crawl through the residue & die later.

Have no idea--I bought it for cockroaches and it did not work very well-at least it is not toxic

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.

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

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.

Yes! I searched far and wide for a good insecticide that would also work for widows. I had 3 different species of widow spiders (Southern Black, Northern Black, and Brown) brooding around my house. I was finding 3-4 a day at one point! I sprayed very well around the perimeter of the house and it knocked the population significantly. All of my neighbors were still complaining about them but none around my house! Just to test it, I once sprayed a specimen directly (it was a Northern Black Widow) before going to bed. I came back the next morning and found it dead on the ground.
