I have 2 young kids. Is it safe to spray this inside the house (around baseboards). Getting ants this winter.

I cannot say anything about the ants but I managed to exterminate cocroaches who are the great survavals. The substance have no smell and did not influence the state of health anyway ,though I used it all around the kitchen floor in all the corners and crevices.Nither of my family members complained. I had to repeat the spraying a couple of times until all the disabled creatures died out. I think that the substunce is magic. Very glad that I was recomended to use it.

Whats the difference in this active ingredient (cypermethrin) and Cyfluthrin?

Cyfluthrin belongs to a class of insecticides known as synthetic pyrethroids. ... Cypermethrin belongs to a class of insecticides known as synthetic pyrethroids, found in Cynoff EC, Cynoff WP, Cyper TC Termiticide, Cyper WP, and Demon WP pesticide concentrates. But that info really won't help you . what product are you trying to compare with demon wp? cy-kick? Both Cykick CS and Demon WP are great products. When sprayed, Cy-Kick CS creates a thick barrier of microcapsules that is impossible for insects to cross without being exposed to a lethal dose of insecticide. Exposed insects pick up microcapsules on their hairs and body triggering a rapid release of the active ingredient, resulting in death. Cy-kick’s active ingredient Cyfluthrin is a pyrethrin, which means it is user-safe, environment friendly, and less likely to cause skin irritation than other active ingredients. Cy-kick CS is virtually odorless, and will not create a visible residue or stain when used according to the recommended label rate. 16 oz. Demon WP insecticide is a wettable powder that is mixed with water. It can be applied as a crack and crevice and/or spot treatment for residual and contact control of ants, bees, biting flies, boxelder bugs, centipedes, cockroaches, crickets, earwigs, elm leaf beetles, firebrats, fleas, flies, millipedes, mosquitoes, pillbugs, silverfish, sowbugs, spiders, ticks, and wasps. Demon WP will leave a white residue on dark surfaces. Cy-kick won't

My daughter has a bad infestation of roaches. Will this work?

Best to use Maxforce magnum roach bait gel and gentrol point source igr discs Or advion roach bait gel and gentrol point source igr discs. For roaches inside.

Does this keep stink bugs and keep them away?

Yes, I spray all around my house, screens, doors etc and they stay away or die shortly after. None have made it indoors in 2 years.

Works Great .... Kills all the Bugs

This stuff works great.Kind of lonely without house spiders though.The bugs seem to know to stay aways since I started using this insecticide.No odor that I can tell. No bugs around. Those big black stink bugs still show up but then roll over dead .... it seemsIt is a rural ranch house and after I used this for a year all of the bugs are gone. Sad to see that it also takes out walking sticks though .... it kills all the bugs.... I really don't want it to kill Praying Mantis .I only use it outside .... I dilute it after half is gone to extend the life of the batch.The packets are very flimsy and don't use make up a batch in the wind. Wear rubber gloves.It cheaper than the already mixed stuff you buy at the hardware store and seems to work better too

It works

So far so good. I was having a little bit of a problem seeing spiders outside. However, after spraying the product, it seemed like it may have worked. However, where I live, it's been raining a lot. So not sure until after the rain dries up after this weekend of August, 21st. I will definitely see. So far so good.

Works great!

This stuff is toxic, but it killed the scorpions I was after. Just read the directions and don’t get it on you. You’ll be fine. It’s easy to mix and apply.
