All About Lace Bugs: Identifying and Controlling Them

Table of Contents

If you are an avid gardener, you know how frustrating it can be to see lace bugs attack your plants. These little pests may seem insignificant, but if left untreated, they can do significant damage to your garden. In this post, we will discuss everything you need to know about lace bugs - from identifying them to controlling their infestations.

What are lace bugs?

Lace bugs refer to a family of insects that measure 3-4 mm in length and have a flat body shape. They feed on the tissue fluids of plants by piercing the cells with their sharp mouthparts. While there are several types of Lace Bugs, the most common ones include the Azalea Lace Bug, Oak Lace Bug, and Hawthorn Lace Bug.

Nymphs and adults of lace bugs can cause damage due to their feeding habits. The nymphs resemble the adult lace bugs but are much smaller in size and lack wings.

Why are lace bugs a problem for your plants?

When lace bugs feed on plant tissue fluids, they leave behind a toxin that can cause leaves to brown or turn yellow. This is because, during the feeding process, they inject saliva into the plant, which can clog up the phloem vessels responsible for nutrient transport. Eventually, this leads to plant death.

Lace Bugs Damage

It is essential to understand the kind of damage that lace bugs can cause to address their infestation effectively.

How do lace bugs damage the plants?

Lace bugs damage plants by puncturing leaves and sucking out the plant's juices. As the lace bug feeds on a leaf, it leaves characteristic rows of white spots along the vein where it has fed. Over time, as the population increases, these white spots gather and coalesce, forming brown, sunken areas on the underside of the leaves.

Common signs of Lace Bug damage

Infested plants' foliage shows stippling, which is characterized by tiny spots or flecks on leaves, stems, and flowers. The undersides of the leaves will have black speckles that are lace bug excrement. Feeding damage may also result in yellowing, browning, or bronzing of leaves.

Identifying Lace Bugs

Identifying a lace bug infestation can be challenging. Here's what to look for:

What are the physical characteristics of Lace Bugs?

Lace bugs are usually small in size, measuring about 3 to 4mm long. Though different species have unique colors and markings, most females generally have lace-like wings extending beyond their bodies' width, while males have wings that cover their bodies entirely.

How to identify Lace Bugs infestation in your plants?

To diagnose a lace bug infestation, check for stippling, discolored leaves, and sunken areas underneath days after the first sign. It would be best always to check both sides of the leaves for any indication of an infestation.

Which plants are often attacked by Lace Bugs?

Despite their name, lace bugs attack a variety of plants, including shrubs, trees, vegetables, fruits, and ornamentals. Some of the common plants include azalea, rhododendron, mountain laurel, pyracantha, sycamore, oak, and hawthorn.

Controlling Lace Bugs

Natural ways to control Lace Bugs infestation

If you prefer natural methods, consider the following:

• Prune the infested areas: This reduces overcrowding, which makes it harder for lace bug populations to explode.
• Provide better watering: Regular watering helps plants develop stronger immunity.
• Use insecticidal soaps and oils: These can be sprayed on leaves to suffocate or dehydrate pests,
• Remove weeds and debris: This removes possible living areas for the bugs.

Chemical treatments for Lace Bugs

If the natural techniques aren't working, consider chemical options such as Spinosad, Carbaryl, or Imidacloprid. Be sure always to use chemical insecticides in the recommended amounts and adhere to the safety precautions.

How to prevent Lace Bugs infestation?

Preventing an infestation of lace bugs is much easier than treating an existing one. Here are some tips to prevent lace bugs infestations from happening:

• Keep the area weed-free: Most weeds serve as home or shelter for lace bugs because they have insufficient resistance to their piercing mouth parts.
• Avoid over-fertilizing: Too much fertilizer will lead to excessive growth and may make plants vulnerable to attack by lace bugs.
• Keep the leaves dry: Reduce humidity and moisture levels, which Lace Bugs thrive in by watering your plants early in the day and ensuring you plant in well-draining soil.

Don't ignore lace bugs! If left unchecked, they can do significant damage to your garden. Prevention will always be the best approach, but if necessary, use natural or chemical solutions to control lace bugs' spread.
