What’s Eating My Calla Lily Leaves? How to Identify and Stop Pests Causing Holes

As a proud calla lily owner, nothing is more heartbreaking than walking outside and noticing ugly holes chewed right through the gorgeous green leaves of your prized plant Your first reaction may be “What’s eating my calla lily leaves?” But don’t despair! In this article, we’ll explore the most common culprits causing that damage, how to accurately identify them, and proven organic ways to get rid of them for good

The Main Culprits: 8 Bugs That Bore Holes in Calla Lily Leaves

If you look closely at the hole patterns and textures left behind, it’s possible to sleuth out exactly which little bugger is the one munching on your lily. Here are the most frequent hungry creatures you’re likely to find:

• Caterpillars – Neat rounded holes in orderly rows means caterpillar hatchlings from nearby butterflies or moths are feasting. These wiggly green worms can devour leaves rapidly!

• Slugs – Ragged, irregular holes between leaf veins signal these slimy slugs traversing plants at night. Their sticky trails crisscrossing leaves are a telltale sign.

• Aphids – Tiny pear-shaped aphids in clusters leave behind yellow spots that turn to holes when populations are high.

• Spider Mites – Tiny spider mites cause stippling on leaves, leaving them looking peppered. Webbing on plants points to these pests.

• Thrips – Tiny worms pierce leaves, leaving dried flecks that fall away and create holes. They spread viruses too.

• Whiteflies – Clouds of tiny whiteflies drain plant fluids, causing yellow stippling that turns to holes. Sticky honeydew and black mold may also appear.

• Japanese Beetles – Skeletonized tissue between leaf veins is the calling card of these iridescent green and copper beetles.

• Earwigs – Jagged notches chewed along leaf edges means these creepy looking pincer bugs are the culprits.

Now that you know which bugs are likely nibbling through your lilies, let’s talk about confirming exactly which one you’re dealing with and stopping them for good.

Inspect Plants Thoroughly to Correctly Identify the Culprit

Closely examining the damage left behind and signs of the bugs themselves when present is key to identifying what’s munching on your greenery. Here are telltale signs to look for:

• Orderly rounded holes in rows indicates caterpillars. Look for green worms on leaf undersides.

• Ragged holes near edges points to slugs. Check for slimy trails on leaves.

• Yellow spots becoming holes signals aphids. Use a magnifying glass to spot clusters on leaves.

• Stippling and webbing means spider mites. Gently shake a leaf over white paper to dislodge mites for closer inspection.

• Tiny dried flecks dropping out shows thrips are present. A magnifying glass helps spot these minuscule worms.

• Yellow stippling and sticky honeydew indicates whiteflies. Shake leaves and watch for tiny white insects flying up.

• Skeletonized tissue between veins is the work of Japanese beetles. Watch for metallic green and bronze beetles on foliage.

• Jagged notches along edges points to earwigs. Search at night with a flashlight to catch them in the act.

Once the culprit pest is identified, take swift action to banish them from your calla lilies and prevent further damage.

8 Organic Ways to Get Rid of Bugs Eating Holes in Calla Lily Leaves

Eliminating these uninvited garden pests doesn’t require dousing your plants in harsh synthetic pesticides. There are several gentler, yet effective organic approaches:

• Hand pick off – Pluck caterpillars, slugs and other large individual pests off by hand and drop them into soapy water.

• Use neem oil – This organic pesticide coats leaves in a sticky residue that disrupts bugs’ feeding and life cycles.

• Apply insecticidal soap – Soap solutions penetrate soft insect bodies, causing dehydration and death on contact.

• Release beneficial insects – Natural predators like ladybugs and lacewings will feast on aphids, whiteflies and other small soft-bodied insects.

• Use row covers – These fabric barriers keep adult insects from reaching plants to lay more eggs.

• Set out traps – Yellow sticky traps draw in and capture flying pests like whiteflies and fungal gnats.

• Practice crop rotation – Moving calla lilies to a different bed each season disrupts pest life cycles.

• Use organic sprays – Products derived from plants like neem oil, garlic, and hot peppers deter feeding.

A multi-pronged approach customized to target the specific culprit bug is most effective. And be sure to take preventative measures like cleaning up debris, fertilizing appropriately, and inspecting new plants to keep calla lilies vigorous and resilient against future attacks.

With some vigilance and organic TLC, you can outsmart those leaf-munching pests and keep your calla lily foliage in flawless, hole-free condition where it belongs. No more ugly predator damage – just beautiful blooms to enjoy all season long!
