10 Tips for Dealing with Caterpillar Infestation: A Pest-Free Home Guide

Dealing with Caterpillar Infestation: Tips and Tricks for a Pest-Free Home

As the days get longer and the weather gets warmer, many of us are excited to spend more time outdoors, enjoying the sunshine and fresh air. But while we enjoy the beauty of nature, we must also contend with the pests that come with it.

One of the most common pests that plague homeowners in the spring and summer months is the caterpillar. Caterpillars are the larvae of moths or butterflies and can be found in various species across the world.

While they might seem harmless, caterpillars can cause significant damage to your home’s foliage and gardens. Some caterpillars can also cause skin irritation or dermatitis if they come in contact with human skin.

In this article, we’ll discuss how you can deal with caterpillar infestations and prevent them from invading your home in the first place.

Caterpillars as Pests

Caterpillars can cause significant damage to your home’s foliage, and some species can even cause dermatitis. Caterpillar dermatitis is a skin condition that is caused when the hairs or spines of certain caterpillars come into contact with human skin.

Symptoms of caterpillar dermatitis include itching, redness, and swelling, and can lead to further complications if left untreated. Foliage destruction is another issue caused by caterpillars.

They can strip plants of their leaves and leave unsightly holes all over your garden. If left unchecked, this can lead to the death of your plants and a barren garden.

So, what can you do to keep caterpillars from infiltrating your home?

How Caterpillars Get into Your Home

Caterpillars typically enter homes through moths, which lay their eggs on plants or in your home. The eggs hatch into caterpillars that feed on foliage in and around your home.

So, what attracts moths to your home? Moths need a food source, and your pantry can be a prime target.

Stored clothing can also attract moths, so keeping your closet and pantry clean and organized can help prevent infestations. Weather can also play a role in attracting moths.

Warm, wet weather can increase the number of insects in the area, leading to more caterpillars that can potentially invade your home. But with proper preventative measures, you can keep moths and caterpillars from becoming a problem.

Keeping Caterpillars Out

Tip #1: Keep Moths from Entering Your House

The first step in keeping caterpillars out is to prevent moths from entering your home. To do this, you need to identify potential sources of attraction, namely, your pantry and closet.

Keep your pantry clean and organized, and store food in airtight containers. This will help prevent moths from accessing your food source.

In addition, avoid storing dirty clothes in your closet. Make sure everything is clean and fresh, and hang clothing on sturdy hangers instead of folding them.

Tip #2: Get Rid of Moths Inside Your House

Sometimes, moths slip past our preventative measures, and caterpillars can already be on their way inside your home. When this happens, manual removal is your best option.

You can remove cocoons and caterpillars yourself, or use a vacuum cleaner to suck them up. Be sure to dispose of them properly, and avoid crushing them, as this can release toxins that could potentially harm your family and pets.

Tip #3: Relocate the Caterpillars

If you don’t want to kill the caterpillars, you can relocate them to a different area. Allow them to crawl onto a leafy branch and then move the branch to a nearby tree or bush.

This will help preserve the local ecosystem and protect your home from further damage. Tip #4: Concoct Soap-Based Homemade Pesticide

If you’re looking for an effective and eco-friendly way to rid yourself of caterpillars, try making a homemade pesticide.

Mix biodegradable soap with water in a spray bottle and apply it to the underleaf of the damaged plant. This will kill the caterpillars, but will not harm the plant or other wildlife in your garden.

Tip #5: Make Homemade Chili Spray

Another organic option is making homemade chili spray. Combine water, chili flakes, and a few drops of biodegradable soap in a spray bottle and apply it to your plants.

This should repel the caterpillars without causing any harm to the plant.

Other Options for Controlling Caterpillars

Tip #6: Use Bacillus thuringiensis var. kurstaki

If you have a severe infestation, you may need to use a more powerful pesticide, but one that is eco-friendly and safe for use.

Bacillus thuringiensis var. kurstaki is a type of bacteria that targets caterpillars while sparing other beneficial insects, such as bees and butterflies.

Tip #7: Use Pyrethrum

Pyrethrum is a natural insecticide derived from chrysanthemum flowers. It is a low toxicity option that can be used to kill caterpillars in your home or garden.

Synthetic versions of pyrethrum are also available if you need a stronger dose. Tip #8: Use a Commercial Garden Pesticide or Bring in a Pro

If your caterpillar infestation is extreme, you might need to use a commercial garden pesticide or bring in a professional exterminator.

Be sure to read the label and follow the instructions carefully to prevent accidental ingestion or misuse. If you are unsure, consider contacting a professional for help.

Tip #9: Build an Insect Barrier

If you have houseplants that are at risk, consider building an insect barrier around them. Wire mesh barriers can be used to keep caterpillars and other insects out while still allowing air and light to circulate.

Tip #10: Keep Clean

Finally, the best way to prevent infestations in the first place is to keep things clean and organized. Regularly cleaning your home and yard, and removing standing water or rotting foliage can discourage insects from setting up shop in your home.

This is an excellent method to keep wildlife away and make an area that is less ideal for pests.


Caterpillars are an annoying but manageable pest. With proper preventative measures and a few eco-friendly treatments, you can effectively manage caterpillars and protect your home from damage.

Remember, the key to keeping caterpillars from invading your home is maintaining a clean and organized environment to discourage moths from laying eggs in or near your home. In conclusion, dealing with caterpillar infestations in your home or garden can seem like a daunting task.

However, by following the tips and tricks outlined in this article, you can effectively prevent caterpillars from infiltrating your space. Whether it’s through proper cleaning and organization, natural homemade pesticides, or eco-friendly commercial pesticides, there are plenty of options available to you.

By addressing the root causes of infestations and using environmentally responsible methods, you can maintain a pest-free home and preserve the local ecosystem. With these strategies in mind, you can rest easy and enjoy the beauty of nature without the interference of unwanted pests.
