- Reviewed in Canada on June 11, 2025Verified PurchaseSilverfish disappeared from my house after 2 months of usage. I sprayed like 2 times per week only. I haven't seen them anymore so I guess it worked. I used literally like 5% of the bottle, now I have so much for another 10 years? lol.

- Reviewed in Canada on October 12, 2024Verified PurchaseWe have ordered this product twice .Absolutely works if you want to kill those ugly ElderBeetles bugs.We wait til later in the day when the Bumbles ,honeybee,and ladybugs are heading to bed.
Those ugly beetles are still looking for a warm place to get into and breed.and breed they do.we have tried all the recipes for bug killers that you see online.Using peppermint oil and Dawn soap,Dawn soap and vinegar etc but NOPE they didn’t work . Atleast for us they didn’t.All they did was coat our new windows and house with an oily film.
We had initially bought this product to help get rid of the horseflies this past summer that we’re bugging ourhorses.Works amazing for that.
Then the end of September comes along with those maplebugs get behind looking for a warm spot to winter.The spray doesn’t say it kills maplebugs but we had some left so what the heck.The first time using the right amount of Onguard with water .It worked but not that great,so my husband mixed a stronger batch and boom it knocked those suckers off the house,they dropped from the inside of the siding …to their doom.Ordered the next jug and we have been spraying the base of the trees and our buildings Can’t say enough about how WELL it worked.Dead beetles everywhere.
Do wait til later in the day when the beneficial bugs are gone for the day
.Then spray away into every nook and cranny, around windows ,doorframes ,any little crack you find.Watch them come out of the hiding place and drop to their doom.Great product.Ordering another jug just to have on hand.This coming spring all those garbage maple trees will be uprooted and burned.Replacing with a much prettier trees. Great price point as well for what it does.
