Cynoff WP - Questions & Answers

Yes. Unless other wise noted,  the pesticides on our website are safe to use in a home with children. As with any product, it is important to follow the label instructions and precautions to ensure safety. Cynoff WP should be used as a crack and crevice treatment indoors.

A comparable product to the Cynoff WP that will not leave a white powdery residue is Cy-Kick CS. Just like a wettable powder, 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.

Cynoff WP will kill scorpions, but scorpions do take longer to kill than other insects. Most insecticides must be ingested for them to work, but since scorpions do not groom themselves like other insects it takes longer for them to get a lethal dose. It is also true that Cynoff WP can help eliminate much of the scorpions food source (other insects), making your property poor hunting grounds and forcing the scorpions there to move and stopping new scorpions from moving.

Yes, Cynoff would be a great option for you. Bees and Wasps: Application to nests should be made late in the evening when insects are at rest. Please be aware that this product has the potential to leave a slight residue over dark areas.

Cynoff WP is safe to use around pets when used as directed on the product label. Cynoff WP is a crack and crevice treatment indoors and when used this way cats would have very minimal opportunity to contact the product. Also, once the product is applied there is only enough active ingredient to kill a tiny insect and not enough to have an effect on an animal as large as a cat.

I believe the Gilmour hose end sprayers have a dial that measure teaspoons of product per gallon of water.  One scoop form the Cynoff WP scooper that come with the container is equivalent to 2 teaspoons.  For most insect control with Cynoff WP, you should mix 2 teaspoons to each gallon of water.  Also, the cynoff WP label says to use one gallon of mixed solution over 400 square feet . Let's say you wanted to spray Cynoff WP over a 1200 square foot area.  This would require 3 gallons of solution, each gallon covering 400 square feet.  Each gallon would require 2 teaspoons of Cynoff WP to mix with the water.  So you should fill your Gilmour hose end sprayer with 3 spoonfuls from the scooper in the Cynoff WP, but set the hose end sprayer on the 2 teaspoon setting per gallon of water, which is probably just turning the dial to the number 2.  You should apply 3 gallons of water through the hose end sprayer, mixing 2 teaspoons at a time over 1200 square feet .  Hope this makes sense.  Hose end sprayers are confusing but can cover a much larger area than hand pump sprayers.  Please feel free to call us if you need any further clarification at 866-581-7378.

Since Cynoff WP only lasts about 30 days outside, you should be fine if your fruit is 3 months away from being harvested.  Also since you washed them off initially you should be fine.

Cynoff WP should be used with in 3 years of the date of purchase. Be sure to keep the lid tightly closed and store the product in a cool dry place.

Cynoff WP is a wettable powder, so it leaves behind a white residue that is noticeable on darker surfaces once dry as it reverts to its powder form, just adhered to surfaces.  It is not labeled to be used on floors as a broadcast, only around the rooms along baseboards, cracks and crevices etc. 

Cyper wp is usually chosen for carpenter because the powder residue sits on top of porous surfaces such as wood while the liquids can be absorbed and are not available to the bees when they land.

Cynoff WP is a great product for scorpions and all other insects.  Cynoff WP comes with a scooper inside the jar.  You should mix 1 scoop per gallon of water for most small insects and 2 scoops per gallon of water for scorpions, spiders, and roaches.

Cynoff WP typically has a life span of 30 to 45 days before re-treatment is required.  Sometimes it can last longer than this.  UV light is the biggest culprit of breaking down pesticide residuals.  Most products, including Cynoff WP, can hold up to rain quite well.  However, if you have a really bad rain spell and it rains for days on end, then this can wear down the product quicker than normal.

It is normal to see the nymph roaches after spraying. Only the insects that actually come into contact with treated areas will be killed by Cynoff.  Basically you have killed off the larger adult roaches with Cynoff WP but you still have egg cases that are hidden away and they will continue to hatch and you will see the smaller nymph or baby roaches. We recommend that you use an insect growth regulator such as Gentrol IGR to help halt the growth of the juvenile roaches. By halting the growth of the roaches you will be able to stop them from reaching sexual maturity which in turn will stop the prodution of new eggs. We also recommend that you use a  roach bait gel such as Advion Roach Bait Gel to get rid of those roaches that hide in areas where cannot spray such as wall voids, cabinets, drawers and cupboards. You can purchase these two products together in our Roach Control Kit #1.

Ants can also be controlled with a bait product. Advion Ant Bait Gel can be applied in areas where you see ant activity. The ants will eat the gel and return to the colony where they will feed the gel to the other ants, effectively wiping out the entire colony. It is very important to avoid spraying Cynoff in places where you apply the roach bait gel or the ant bait gel to avoid having the insects reject the bait.

Cynoff WP cannot be used in a septic system nor can any other insecticide we carry be used down drains. Roaches would only be coming from the drains if there is a crack in the pipe allowing them to come in.  You would generally only see roaches coming from drains after they have gone down to get water.  For roaches in a home we would recommend one of our Roach Control Kits and also have a great guide that explains the best treatment to eliminate them.

Cynoff WP will indeed kill the wasps. You should spray either very late in the evening or very early in the morning when the wasps are less active and less likely to sting. Cynoff WP does not offer an instant knockdown, but it does have a long lasting residual effect.

Yes,  Cynoff Wp is a great product to use as it is labeled to treat ants, earwigs, and spiders.  You may also, want to check out our Complete Ant Kit, as we recommend using an ant bait to eradicate many different types of ant colonies.

Cynoff WP has been discontinued by the manufacturer. We would recommend using Demon WP or Cyper WSP instead.

Cynoff WP is not labeled for termite control. There are many products on the market that work very well for termite control and are labeled for termites. Termidor SC is the most popular termite treatment and when used as directed it will last for 10 years or more in the soil. Dominion 2L is a low cost alternative to Termidor SC and when used as directed it will last up 7 years in the soil.

Cynoff WP will kill springtails.  However, springtails will not completely go away until you address the moisture issue.  Springtails breed in areas of high moisture content.  If you have a springtail problem, then it is because there is a moisture issue somewhere around the house.  Please read this article on Springtail control. 

Cynoff WP is not labeled for bedbugs so we cannot recommend you use it for bedbug control.  For more information on a successful bedbug treatment program, please review our article on How to Get Rid of Bedbugs.
