InVade Bio Drain 1 Gallon (Original Version)

An essential weapon in my anti-drain fly arsenal. I was a bit put off by the cost at first, but it’s very concentrated. I consider it one of many elements I brought to this battle. Essential tactics included being extra clean, particularly right after meals were cleared. So I’m writing this product as a component of a multi product and behaviors war on drain flies not as a standalone cure all.By that measure meaning as an element of a mini prong attack, I think this product was fantastic. I would caution against dumping the entire thing down the drain and one go. That would be expensive and you really need to use this in conjunction with cleanliness, boiling water, and an effective drain cover, especially for overnight.

I had all these stupid tiny bugs that kept climbing up my shower drain in the night. I tried boiling water and bleach on multiple occasions. None of it worked. I did have to apply this a few times, but it's a whole gallon, and I only used 4oz each time. They were gone so quick, and I've yet to see them back! Definitely a product I'll keep on hand just in case it's needed in the future.

July 31st we ordered and August 1, 2023 arrived Invade Bio Drain. We were having an invasion of small flies (not sure if they were gnats or phorid flies). We purchased different kinds of devices to control these pesky visitors.The last device is pictured here. This trap would quickly fill up and we would have to replace it every other day (see photo).At wits end, we searched the internet and came across this product, Invade Bio Drain. We followed the instructions of every other day and started seeing results in the first week of using it in every drain (including the dishwasher). Now here we are, August 29, 2023 and we barely see anything flying around (see 3rd photo; this has been this clean since yesterday. Previous to using Invade Bio Drain, this trap would have looked like the first photo by now).Now we are using Invade Bio Drain once a week I guess for preventative measures?The only thing I disliked was not having something to dispense the Invade Bio Drain as instructed. Do not pour this straight down the drain. Make sure to pour this so that it is coating the sides of the pipe. But I see photos of squeeze bottles used by other consumers that look like it helps on the application and coating the walks of the pipe.Not crazy with the price but after being inundated with small flies, we would give an arm and a leg to stop the invasion.But this was a GREAT purchase for us!

I have been using this product for years to free my drains from pests that lay eggs. It really works well and works quickly.

Takes awhile to work, but works. Very expensive for the number of applications having to use

After battling fruit flies for over a year to no avail and seriously having them mess with my mental health - I used this on my bathroom sink drains, shower drains, and kitchen drain and I stop seeing fruit flies within a week. I’m still in disbelief because I have been dealing with them for over a year and nothing worked. The boiled water didn’t work the gobbler stuff didn’t work. Nothing worked except this. FYI, it’s been over a month now and still no fruit flies. It’s honestly a miracle.

I had a minor drain fly problem. The solution left the drain smelling decent (citrus scent), but I noticed no impact whatesoever on the drain flies. I note that the label doesnt mention drain fly treatment. My purchase was based on other reviews that used it for drain flies. Cant recommend it for drain flies.

Works good for maintaining your drains.
