How To Control Bladderwortbladderwort control

There are invasive weeds that can muck up ponds and lakes but there are few of these plants that are actually carnivores. One of them is the bladderwort. Bladderwort is a free-floating, fresh water, carnivorous lake weed with over 200 species located throughout the world. Bladderwort is usually found in quiet, shallow, waters that are acidic.

The characteristics of bladderwort include a main stem which has 4 to 10 delicately branched lateral leaves that give it a very lacy appearance. The main part of the weed lies beneath the surface and will go unnoticed until it rises to the surface in the late Spring early Summer. Once at the water surface the weed sends up small attractive yellow flower. Bladderwort flowers have lip-like petals which look similar to Snapdragons.

One of the most interesting things about the bladderwort is the reason the plant is given its name: for their underwater leaves which small oval “bladders” which can open and close to trap aquatic insects and other small organisms. The bladder works like a vacuum, where when the pray is close by the weed or touches it, it is sucked into the bladder and consumed.

On a pond or lake, bladderwort hardly brings any benefit to the ecosystem as no sea creature or wildlife animal likes to eat it which means it’s population can get out of control if left untreated. If you have bladderwort on your pond or lake, get rid of it using aquatic herbicides from Solutions Pest and Lawn.

How To Get Rid of Bladderwort: 3 Step Solution

Removing bladderwort from a lake can be quite a difficult task, even for those experienced in treating aquatic weeds. However, with the right approach and selecting the right aquatic herbicide products, you can eliminate large accumulations of bladderwort with relative ease. The fastest way to do such is via chemical control as manual control can be time-consuming and labor intensive. We do want to stress that when conducting chemical control, it’s not just a matter of pumping chemicals into the lake or pond. That can be quite unsafe and irresponsible. Below you will find a simple three step solution where, if followed, can safely and conveniently eliminate bladderwort.

Step 1: All chemical control treatments should start with a careful inspection and survey of the body of water. We recommend that you take into consideration how the body of water is used as well as the ecosystem which lives amongst it. Also take into account how the lake or pond is used by home owners and fishermen. The size of the lake or pond also should be taken into account. Asking yourself these questions will help you to determine what the best aquatic herbicide should be used for your particular situation.

Step 2: Once factors like plant and human considerations are figured out, you can than move on to selecting a control treatment method to manage the bladderwort. At Solutions Pest and Lawn we have a plethora of different aquatic herbicides which come in either liquid or granular formulations. Liquid herbicides like are a great solution because they attack weed growth in shallow water on or above the ponds surface and can be spread evenly with a pump sprayer.

Granular herbicides are best utilized when weeds are submerged as blankets under the water surface, in deep areas of the pond or in ponds with flowing water. These heavier granules can be applied with a hand spreader and will sink directly onto the weed beds. What you select is up to you, we have some recommendations below.

Step 3: Apply the herbicide of your choosing to your pond or lake during ideal temperatures. Depending on the size of your pond, you may need to treat the pond in sections, waiting 2 weeks between treatments until you’ve treated the entire pond. There is a more
