How to Get Rid of Caterpillars Inside My House

This page is an expert guide on getting rid of caterpillars from your home using the products and methods suggested by our experienced pest control specialists. Follow this guide and use the recommended products and you will eliminate caterpillars from your house, guaranteed.

The caterpillar is largely a harmless insect and when they grow up to become butterflies, they look undeniably gorgeous. But when their young ones crawl into your home, they are not only unsightly but unsanitary as well.

A caterpillar can potentially host different germs and otherwise, mar the sanitation inside your home easily enough by its mere presence. If they are out in your garden, they can be damaging to the vegetation. Caterpillars can also sneak through openings and cracks in your home and nibble on your indoor potted plants. If you are dealing with a caterpillar infestation, read on to find out what you should do to get rid of the pest.


Caterpillars are the larvae stage of moths and butterflies. There are over 180,000 species of caterpillars and they come in different color patterns and sizes, but the common characteristics are that they are long, wiggly and hairy. They are soft-bodied, have three pairs of real legs and then six false legs that help the caterpillar cling and climb onto plants. Caterpillars like to eat plants and are known to be very destructive in garden and agricultural settings.


Where To Look

Caterpillars often make their way in the home from outdoors where there is a garden of lots of vegetation. If you experience a caterpillar invasion the odds are that they came into your house by piggybacking on some plant or vegetable you've brought into the home or through cracks or holes in your screen and or even though open windows. This holds even truer where your porch or windows open directly to foliage right outside, of if you have hanging potted plants in your balconies and windows. Since the butterfly will deposit its eggs on the plant, they will hatch and the little caterpillar will be able to crawl its way into your home.

What To Look For

Caterpillars move slowly so it's likely you'll see the caterpillars themselves moving around in the home. Aside from this, another sign of caterpillar presence are the stains they leave behind. Many caterpillars have a rather annoying tendency of ‘oozing’ their way across walls and floors like common garden slugs. This means that their residue has to be cleaned up, otherwise it stains the walls and floors where they have been.


By far the single most effective method of dealing with these unwanted visitors in your home is via insecticides. The trick is to use products that are effective in killing caterpillars but also can be safely sprayed on plant life without harming the plants. This is why our experts recommend Cyonara 9.7.
