How to Get Rid of Caterpillars Inside My House

The ubiquitous caterpillar may well be the single most harmless insect out there, and when they grow up to become butterflies, they look undeniably gorgeous. 

While it is all very well to look at them from a distance and snap pictures, but when their young ones make your home, their abode they can look not just unsightly but also unsanitary as well.

After all, the last thing you need in life when you invite your boss over for dinner to ask for that coveted raise is to see a caterpillar making its slow progress right across your salad bowl. (and if your boss is into fresh green veggies, it will probably be curtains towards any raise in salary, anytime in the foreseeable future).

However, it does not always have to be this way, since caterpillars don’t just appear out of thin air, nor are their parent butterflies (or even moths for that matter) are in a habit of laying their eggs inside people’s homes for any particular reason.

If you are blighted by a caterpillar invasion the odds are that these guests came into your hose by piggy backing (inadvertently of course) on that fresh green salad you may have purchased, or for that matter though 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.

While it is not even remotely dangerous, however it can potentially host different germs and otherwise, mar the sanitation inside your home easily enough by its mere presence. There is no one particular species of caterpillar as regards their shape, size, and coloring. As a matter of fact, they come in all shapes, and colors and even textures (some of them are smooth while others may be quite hairy). Since they both live on and also live ‘off’ plants, they can easily wreak havoc with all of your indoor and outdoor flora. Especially since they can easily chew holes on a leaf or stem even bigger than their circumference, within mere minutes. From the caterpillar’s point of view this is essential behavior if it is to hit its next stage of development i.e. the pupa from which it can mature into a butterfly. But the plant on which they live, will end up with a decidedly bedraggled appeared. This is precisely why it is imperative that they be gotten rid of, as soon as possible.

Apart from that, 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. This is why when you see a caterpillar in your home you should swing into action post haste. Following are some of the best ways of going about doing that:

  • Method one: Sweep them off

You can use a large broom to simply brush off the caterpillars from both the exterior and the interior walls of your home, at least once or twice a day. In fact, you should do that the minute you see one ‘blazing a trail’ across your bedroom wall. You can do the same to the windows and screen doors as well. Afterwards, sweep them up in a dust pan and unceremoniously deposit them where they belong, i.e. outside your home, where they will no longer be a nuisance to you and yours.

  • Method two: Pluck em out

Put on a pair of surgical gloves and simply pluck them off the furniture, the walls and your salad bowl or any other place you see them. They may be found on counter tops and especially on plants, this is why you should thoroughly check all your houseplants to see if there are any around. You can either throw them out or flush them down the garbage chute.

  • Method three: Use a pesticide

This is by far the single most effective method of dealing with these unwanted visitors in your home. Just about any common insecticide spray can handle them easily enough. Spray the areas where you see movement or directly spray them whenever they make their appearance. You can also liberally spray all of your different plants to ensure that there is no recurring infestation. The better pesticides contain chemicals that can easily get rid of the nits and eggs as well as the pupa in which the caterpillars envelop themselves in their post larva stage. You can also dust your plants with insecticide powder and do the same on the floors of your house.

Here at Solutions Pest & Lawn, we have a wide array of products which can successfully take care of a caterpillar issue. Some of our suggested products include: Cyonara Lawn & Garden RTU. This product can safely be sprayed on plant life without harming the plants. Spray Cyonara on the plants and leaves when the caterpillars are young. The insecticide kills the caterpillars immediately on contact.

Another recommended insecticide is Tengard SFR Permethrin Insecticide. Spraying this over the trees and plants impedes the growth of the caterpillars as it gets terminated. This curbs the growth and spread of caterpillars.

  • Method four: Beware of the cocoons

The caterpillar is primarily a form of insect larva and therefore, it will evolve into a pupa after a certain period of time. In the case of moths that feed on cotton, this is a particularly annoying phase since many such larvae are essentially immune to the spray you use to get rid of them. You should use a hard wire brush to sweep the pupas from wherever they may have established themselves, such as walls or inside your clothes for instance to ensure a caterpillar free existence.


With the help of our methods and product recommendations we laid out above, caterpillars should no longer be a problem on your property.
