Bonide 857 Pyrethrin Spray Concentrate, 8-Ounce

Can always depend on pyrethins to get the job done.

This is my all time favorite pesticide now. I've used 2 gallons of it so far. I've tried the common solutions sold in hardware stores but when you spray a cellar spider with the conventional stuff and it's still there the next day, it makes you sad. And terrified that the spiders will demand half of the bed soon when they start moving in.Spiders are particularly hard to control because they only touch the ground with their tiny, tiny feet in their tiny, tiny spider shoes. The insecticides at the store claim to leave a residue that works for long periods of time but truly, they don't.Pyrethrin is a contact insecticide and it starts working in 5 minutes, job is done within 20. I've used it on a variety of spider species as well as roaches. It's really good when you have 18 ft ceiling and are being taunted by a bug at the very peak of it. The spray with knock them down and if you don't get them immediately, they'll be dead under the TV stand in a few minutes anyway. That's peace of mind.So in short:PROs:EVERYTHING but more specifically:1. This is a squished up flower that kills insects. It's naturally based so I can use it inside the house with pets and boyfriends and all is well. I've made myself sick from chemical exposure before (55 welts on my back, no insect bites) after laying out insecticide powder. I don't have that concern now. That being said, don't drink it on a dare.2. Visibly works and quickly. 20 minutes, dead spider. every single time. roaches too.3. Doesn't smell terrible. I don't get a headache or any side effects from using it in small spaces in the house.4. Contact insecticide only. Both pro and con. You spray what you see. Once it dries, it doesn't pose a risk to beneficial insects.CONs:1. Contact insecticide - must spray bug to work. Since I've had no luck with the chemical stuff, this isn't a problem for me but I wage spider wars. This may be a con to you.2. Won't eliminate bills or people. I think that's really a pro, right? [Note to self: do research on this]PRO TIP: Another really good natural insecticide for your garden is Neem oil. It's as effective as pyrethrin on aphids and such. I tried it out this year in mine. Both are harmless but neem is traditionally used in the garden because edibles benefit from the neem oil itself on their leaves.MORE FUN WITH KILLING: Update. I opened the flue on my chimney and had a few hundred wasps fall in the fireplace. 75% were dead, 25% were not. After dressing in full armor (basically clothes and shoes), I sprayed them down and killed the ones still moving around. Then since the flue was still cracked, I did it again the next day with the new visitors. Stuns them quick, dead in 30 minutes. The smell didn't linger in the fireplace either. Good stuff.

The bugs were off the charts on my orchids this spring. This has been the best contact killer for a bunch of them....not to mention the pesky aphids on my hibiscus. I am winning the war finally. NOTE: If you like organic bug killers, this is made from the Chrysanthemum flower and is a natural way to treat bug infestations. You can even use this to get rid of red ant hills. I found out about Pyrethrin on a tv show about a guy that killed bugs. He was right, this stuff is the best all natural treatment for bugs. This will not leave a long lasting residue...this should be used in addition to a systemic bug killer for better prevention and control.

I have an aloe plant that unfortunately came up with an infestation of "fungus gnats." Not a pleasant thing to have in your office to say the least.Suggested on the label is 3 to 5 tablespoons of concentrate per gallon. I went "middle of the road" at 4. I purchased a spray bottle from Home Depot, and filled it with the mix.I then sprayed a pretty good coat over the plant and directly on the soil (to kill larvae / eggs as well as adults). 2 days later, and the infestation is gone! I also wanted to explore the general bug-killing capabilities, and sprayed it on some other random bugs I don't like, and they don't make it very far. If you read the list of pests it kills - it will kill about anything.Camping - believe it or not this stuff is non-toxic to humans (within reason, don't drink a gallon). It is actually completely safe to mix up a batch and spray on clothes you'll be taking camping, or to also spray directly on your legs/arms. If you don't believe me, google "pyrethrin toxicity." You'll find info from the US government and from plenty of colleges, all telling you this is safe to do (and likely safer than DEET based products like "OFF"). When I used this for camping trips - we would treat our clothes ahead of time, and also use it in place of "OFF" spray or other brands that use DEET. Pyrethrin works better if you ask me. However, doesn't really smell any better than DEET based brands.Other notes: This product breaks down fairly quickly when exposed to the general environment (especially light). So, if you use this as a bug-killer, you'll probably have to reapply every week, maybe a bit more frequently depending on the pest.Words of warning: This is pretty toxic to cats and dogs, more-so to cats. It is worse for cats as they are not only smaller, but metabolize it more slowly. I have 2 cats, so I just have to be very careful when I use it, and wash very well my hands or anything else I got it on if I am to touch them. If you have pets - read the warning labels and do some research to make sure you don't harm your pets!

Does the job handling Silverfish - leaves a pretty strong scent. Make sure to have an air refresher near by — but very satisfied so far.
