What To Consider When Purchasing Brush Killers

Brush killers are state-of-the-art chemical solutions that elevate weed and garden shrub management to a whole new height. The problem however is that there is an increasing rate of available options in the market that makes it hard to decide which one best suits your specific needs.

To help you out with that, we’ve laid out a few considerations for you when on the lookout for the specific brush killer that suits your requirements.

These considerations are as follows:


Unwanted shrubs and weeds in the garden degrade its value as well as its aesthetics. If you’re on the lookout for a brush killer, then you may simply want to check on its effectiveness on the specific kind of shrubs and weeds you are looking to eliminate.

A good way to check the products effectiveness is by simply looking at the chemicals that are listed in its ingredients. Make sure that the potent ingredients are approved and recommended by experts and are safe for general consumption.

Another way to check its effectiveness is by referring to product reviews and feedback from previous users and customers. Check out reviews for recommendations as well as important notes regarding the pros and cons of using the specific product.



If you’re buying products that use certain uncommon chemicals, you need to make sure it is safe. Just like when buying anything, you always need to consider safety a top priority – it should be safe for users as well as for the environment.

For this consideration, it is important to read the safety notes written on the product.

You can find two forms of brush killers in the market today – the concentrates and the working solutions. Concentrates are the non-diluted solution and would require you to reconstitute them prior to use. On the other hand, working solutions are ready to use right out of the box.

Both are effective at killing unwanted shrubs as well as weeds in the garden. The only difference is that the latter seems to be more expensive.

Water Resistance


The ideal brush killer shouldn’t be washed away so easily. Rains are an inevitable phenomenon that could wash away the applied solution anytime and the last thing that you want to do is apply the solution again.

Today you can find many varieties of brush killers that are set in place for many hours and even days. Aside from checking the label, you can also ask previous users about the product’s resistance to water and how long it can last.


Many people probably would try to ignore this criterion but the best brush killers out there are those with the best brand names. This is for the reason that better brands have established names in the industry and are already known to deliver good-performing products.

If you don’t want to lose money experimenting with a new brand that hasn’t been tested, stick to the popular brand – you’ll be thankful you did later.


As a final thought, which among these top 5 brush killers is best suited for your needs? To be honest, all of these options will work perfectly in your kind of dilemma with regard to weeds and bushes in your garden.

Probably the only determining factor would be the price and the volume of the solution – especially if you’re looking to cover a large area in your garden. For that, we would recommend the Bayer Advanced 704645.

This is on the grounds that it is relatively cheaper than other brush killers available today and that it can contain more than enough amounts of solutions to cover bigger areas of gardens or lawns. Also, it can kill a wide variety of weeds and brushes.
