The best way to avoid pest problems in a greenhouse is to keep them out to begin with. The list that follows gives many ways to help keep a greenhouse pest free. The more of these that can be integrate into greenhouse gardening practices, the better chance a gardener will have of winning the war against undesirable garden pests.
Start Plants from Seed
If plants are bought at a nursery or a garden center, one can not be assured that the plants are perfectly clean. If one has been getting plants from a reputable producer and has not had problems in the past, it would be a good idea to stick with that grower, even if the prices are higher. Treated seeds are safer for starting your greenhouse plants. Untreated seeds are more likely to carry a seed-borne bacterial or fungal disease.
Repot Plants Outside the Greenhouse
Repotting plants should be done outside of the greenhouse, and any used pots should be cleaned and disinfected with a 10% bleach solution before use. Commercially available soilless mix should be used as the media for seed starting and potting greenhouse plants. This will allow one to avoid introducing insect and microbial pests that often live in soil.
Protect the Work Area
Protect the ground on the floor of the greenhouse with a barrier to keep soil born pests from digging their way in from the outside. Work in the greenhouse first before working in the outside garden. Outside plants should not be kept near the greenhouse door. These plants can be a safe harbor for bugs waiting for a chance to get in the greenhouse.
Hands should always be washed before going into the greenhouse. This is particularly important after working with plants, or produce in the kitchen.
If one has been in close contact with plants, grass or dirt/mud, a change of clothing may be in order before entering the greenhouse. If one has been walking through grass or mud, it is a good idea to remove footwear, before entering your greenhouse. If one will be walking in the woods or a wooded area under trees, or even just walking on dirt paths, try to do it after working in the greenhouse.
Consider possible contamination by visitors to the greenhouse. Visitors should not enter the greenhouse after being in another greenhouse, a garden or an agricultural field.
Clean the Tools
Insects, mites or diseases can be taken into the greenhouse on garden tools that have been used outside. Tools should be thoroughly washed and disinfected with a 10% bleach solution before bringing them in the greenhouse and in between working on separate plants.
Items that have been exposed to plants or produce are a source of contaminants. Used plant shipping boxes and produce shipping boxes may be very useful, but they should never be taken into the greenhouse.
No Pets Allowed
Dogs and cats, that live or spend time outdoors, should never be allowed in the greenhouse.
A Few More Things
Screen air intakes to the greenhouse with a very fine mesh. The screen area should be at least five times the area of the greenhouse air intake, as to not restrict airflow.
Consider if a double door is possible. This is particularly helpful in keeping moths and butterflies out. Moths and butterflies are not generally a problem themselves, but when they lay their eggs on your plants, they will soon hatch caterpillars and start to eat their hosts. On your daily bases remove any of them that are present.
Sticky fly traps can help in early detection of some flying and crawling pests.
Inspect plants as often as possible for visual predators or damage caused by harmful pests, fungus, bacteria or disease.
How to Kill Vegetable Garden Pests with Ease
When it comes to harvesting the vegetables from your garden, you don’t want to find out they’ve been destroyed by insects or pests. Luckily, it’s quite simple to kill any pests that may be damaging your crops.
- Slugs and Snails
Both slugs and snails are commonly found in gardens, but unfortunately, these pests are notorious for damaging crops. Not only do they feed on crops, but they also only come out at night, making it tricky to kill them during the day. Slugs and snails also lay many eggs, which can lay dormant for several years before they hatch.
If you’re struggling with a slug and snail infestation, try a beer bath. Simply place small vats of beer around your garden. Slugs and snails are drawn to the yeast in beer. However, once they try to drink this yeasty beverage, they will fall in and drown.
Perhaps one of the most destructive insects, aphids love to drink the sap out of any plant in your vegetable garden. They even spread diseases. If you notice signs of an aphid outbreak, then you should make an organic insecticide out of dish soap.
Simply mix a few tablespoons of organic dish soap with a quart of water. Add a couple drops of orange or lemon essential oil. Spray this concoction directly onto your plants, making sure to fully saturate the leaves. This dish soap insecticide is also effective at killing other vegetable garden pests, including mites, mealybugs, and whiteflies.
- Cabbage Root Fly
The cabbage root fly is known for destroying vegetables by damaging the roots. These pests lay their eggs at the base of plants. When the eggs hatch, the maggots burrow deep down to the roots, where they feast. This can quickly kill your vegetable garden.
If you notice damage to the roots of your crops or you find maggots on the roots, you can quickly remedy the situation by placing a cabbage collar around the base of your plants. This will prevent any newly hatched maggots from reaching the roots.
Rodents, including mice, rabbits, moles, and squirrels, are always looking for their next meal. However, you don’t want them feeding on your vegetable garden. Spraying a mixture of soap, chili powder, and garlic onto your vegetables is one of the best ways to deter these pests. It even works to repel beetles, slugs, leafhoppers, and borers. This mixture will also keep your family pets out of your garden without harming them.
It doesn’t take very much effort to keep your vegetable garden healthy and free of insects and other pests. Natural and organic products are often all that’s needed to deter or kill these unwanted visitors.
Nasty mosquitos can be one of the problems in a home. When they sting its itchy and may cause diseases. The foggers are handy in ridding them.

Get Control Of Your Garden By First Knowing Who The Enemy Is
Every now and then, people encounter intruders in their gardens and they don’t know how to react. Unfortunately, there are many different animal species that can infest your garden and live off of your vegetables, fruits, or even flowers. The thing is, it’s kind of impossible to expect that everyone will know everything about potential infestations and pests.
That’s why people aren’t strangers to exterminators and wildlife experts, depending on what type of animal we’re talking about. Although, something can be said which I think most people would love to hear. In short, you’re entirely capable of dealing with an infestation yourself. You don’t need any expensive services and people that’ll deal with the infestation instead of you (of course, if you tried everything and nothing works, the exterminators are a good option).
In this article, we’ll be talking about how you can gain control over your garden and what’s in it by identifying what type of animal is bothering you. We’ll also mention something about how to get rid of mice in the garden (as they’re also a type of pest that may annoy you).
Identify the Enemy
Each pest can be dealt with as long as you know what you’re doing. But before you actually start researching about the various methods to get rid of vermin from your garden, you’ll need to figure out what exactly is ruining it.
The most common pests found in the garden are raccoons, mice, rats, and others. With the exception of mice and rats, killing wildlife isn’t exactly allowed (unless you have a permit, and some US states don’t allow those either).
You best hope that you’re dealing with mice or rats because it will take a bit more effort for anything else.
Prepare your Defenses
Once you’ve identified the enemy, you’ll be entirely capable of setting up your defenses. When talking about mice or rats, your best bet would be to get traps. And, luckily for everyone, there are many different traps available. For example, snap traps are great against mice but not very effective against rats.
Then again, there are specific rat traps as well. But, if we’re talking about raccoons, squirrels, or even moles – you won’t exactly be able to kill them. Just to be safe, make sure you use live traps (otherwise called catch & release traps). Also, bait choice is very important so be sure to educate yourself on this as well. Peanut butter should work great for most pests, but again, knowledge is everything.
And that’s basically it. Place your traps in potent trap locations such as entry points (doors, windows…), and throughout your garden. Also, make sure you keep your garden clean and without clutter. Most pests will have to find shelter, water, and food. The entire process isn’t difficult, but if you, for whatever reason, can’t clear out your garden – call the professionals. Additionally, ask them for some tips so if there’s another infestation, you have a bit more knowledge with you!

Preventing Pest Infestations in a Greenhouse
The spring season brings new beginnings for plant growth. The landscape becomes green again and multitudes of colors and fragrances fill the air as flowers break through the ground’s surface. The new life brought on by spring is rejuvenating for horticulturists. It is not just plants and flowers that “come alive” during this time of year. Just as new plant life emerges all around us in spring, new life for pest insects is also resurrected. As temperatures rise and the summer months approach, more and more insects leave dormancy and begin new life cycles. This is why it is so important for greenhouse gardeners to be aware of and take counter measures against pest insects during the spring and early summer seasons. In many cases, a few simple preventative steps can reduce the likelihood of a devastating pest insect attack.
Sanitation is the number one defense against pest insect infestations. Keeping the greenhouse and the plants clean and tidy can do wonders in preventing pest insects and pathogens. Periodically wiping down the surface of the greenhouse and removing dead or dying vegetation will greatly reduce the possibility of pest insects. Plants should be closely monitored for pest insects on a weekly basis (at the very least).
It is a good idea to set up a quarantine area in the greenhouse. Whenever a new plant is purchased or gifted, it should be quarantined immediately for a week or two to ensure it does not harbor pest insects. After the quarantine period is over and the plant has received a clean bill of health, it may join the other plants in the greenhouse. Bringing new plants into a greenhouse is the most common way a greenhouse gardener will introduce pest insects into his or her own garden. If pest insects are observed on any new plant, it should be thoroughly treated before being introduced to the other plants in the greenhouse.
Monitoring for Pests
As previously mentioned, it is important for greenhouse growers to monitor their gardens for any signs of pest insects. Yellow sticky traps are great tools for monitoring a greenhouse. Yellow sticky traps are similar to fly paper in that they “catch” flying insects in a glue-like substance. By closely examining the yellow sticky trap, a gardener can see if and what types of pest insects are present in the garden. Yellow sticky traps allow a horticulturist to identify potential problems before they get out of hand.
Identifying the Pest Insect
Identifying the pest insect early and accurately is vital to stopping a few pest insects from becoming an infestation. When monitoring the plants, there are some tell-tale signs that will indicate which pest insect a gardener may be dealing with.
The first sign of a spider mite problem usually shows up in the form of yellow speckling on the surface of the leaves, which is caused by the insects sucking nutrients from the underside of the plant leaves. The speckling from spider mite damage will resemble light yellow spray paint misted on the leaves. Closer examination of the bottom of the leaves will reveal clusters of very tiny red mites and their eggs. A magnifying glass may be necessary to see them. In more extreme infestations, webbing may be found in-between or on the tips of branches and leaves. This webbing looks very much like a spider web and is how these nasty bugs received their name. Spider mites are difficult to get rid of and require a miticide for treatment.
The first sign of mealybugs is normally cotton-like, fluffy masses found in the crotches or joints of the plant, typically near young tender growth. These tiny “cotton balls” are actually clusters of the slow moving mealybugs. These bugs can reproduce and lay eggs every seven days, so they should be treated immediately to reduce any possible contaminations. It’s difficult to kill the eggs, often in the soil, so it’s important to treat for live mealy bugs every five to seven days for three to four weeks to terminate all adults before they become mature enough to lay eggs.
The first sign of a fungus gnat problem is typically the small, mosquito-like, black or gray insects that fly around aimlessly. They are most prevalent right after a watering or when the soil is disturbed. Fungus gnat larvae look like tiny, light-colored worms that wiggle around in the top layer of soil. They can sometimes be seen “dancing” in standing water after a feeding.
The first sign of a thrip issue is usually “shiny streaks” that show up on the surface of the leaves. The shiny trails are actually the areas of the leaf where the thrip larvae have been feeding. Gardeners may also notice tiny black specs on the leaf surface; this is actually the larvae’s fecal matter. To the naked eye, thrip larvae resemble fast moving grains of rice. The larvae can be many different colors, but are usually yellowish-green.
The first sign of scale is usually a protective covering or bumps on the stems and stalks of the plants. The females lay eggs underneath the protective covering, which will hatch in one to three weeks. The newly hatched nymphs leave the protective covering as tiny white specs and move around the plant to feed. Nymphs insert their piercing mouthparts into the plant and begin to feed, gradually developing their own protective covering as they turn into immobile adults. Scale do not pupate and may have several overlapping generations in one season. A scale infestation is difficult to eliminate and requires a systemic insecticide.
Treatment and Control
Early detection and treatment diligence are the keys to eradicating pest insects. A gardener can start treatment with an organic or all-natural insecticide that is designed for the particular pest insect he or she is battling. Yellow sticky traps are effective in capturing most flying insects, such as fungus gnats and white flies. Denatured alcohol is highly effective as a combatant against mealy bugs and scale by wiping it on the infected areas with a cotton swab or small paint brush. Pyrethrum is an organic derivative of the chrysanthemum plant and is extremely effective against many greenhouse pest insects. Pyrethrum is the primary ingredient in several commercial spray products commonly available at most garden centers. In some cases, a pest insect (scale and mites), cannot be controlled with an organic or all-natural approach.
When this occurs, the gardener may need to implement a systemic chemical control. Systemic pesticides, such as Orthene, are effective against pest insects because they enter the plant’s tissue and kill the bugs as they feed on the plant tissue. Regardless of the treatment program, horticulturists should always use caution and be sure to read the manufacturer’s directions for application.

Conventional Pesticides Versus Minimum Risk Pesticides
A pesticide is any substance or mixture of substances intended for preventing, destroying, repelling, or mitigating any pest and will make claims of this on the label and advertising. Any substance falling within this definition of a pesticide must be registered by the Environmental Protection Agency (EPA) before it can be legally sold or distributed in the United States. Section 25(b) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) has determined a Minimum Risk Pesticide does not require EPA registration because it poses little to no risk to human health or the environment. Individual states may still require registration of minimum risk pesticides.
Even the most careful indoor gardeners can suffer from insect and disease problems with their plants. Minimum risk pesticides are made from natural ingredients that have proven over time to defend against insects and disease, making them an effective option for prevention and control that is also non-toxic to humans. Minimum risk pesticides are generally a solution of botanical oils from herbs such as clove, thyme and rosemary. They work on contact by smothering and dehydrating insects and disease spores while providing a barrier preventing pest establishment.
Things to Consider When Selecting a Minimum Risk Pesticide
Safety and Use
It is important to remember that these products are still pesticides and though their ingredients are naturally occurring, it does not mean all of them are suitable for consumption. Not all minimum risk pesticides are allowed for use on food crops. EPA regulations are very specific on which products are allowed and which are not. A product label should clearly list specific insects, diseases, and the crops they can be applied on.
Ingredients Approved for Use on Food
Castor oil (U.S.P. or equivalent), cinnamon and cinnamon oil, citric acid, cloves and clove oil, corn gluten meal, corn oil, cottonseed oil, garlic and garlic oil, geraniol, mint and mint oil, peppermint and peppermint oil, potassium sorbate, putrescent whole egg solids, rosemary and rosemary oil, sesame (includes ground sesame plant) and sesame oil, sodium chloride (common salt), soybean oil, thyme and thyme oil, white pepper
Ingredients Not Approved for Use on Food
Cedar oil, citronella and citronella oil, dried blood, eugenol, geranium oil, lauryl sulfate, lemongrass oil, linseed oil, malic acid, 2-phenethyl propionate, sodium lauryl sulfate, zinc metal strips
Efficacy and Control
There are significant differences in efficacy and control when using natural products. It may cost a little more, but purchasing the right product should resolve your pest problem and be safe for you and your plant. An easy test is to compare two products with the same active ingredient at different price points. The higher priced item is likely to have more active ingredient leading to a greater chance for control. Research the products before you make a purchase, a little digging can give you a lot of insight into what goes into making and supporting each product. For example, can you find test data to prove efficacy? Has a product been formulated using new techniques or technologies to give it a performance edge? These questions are just the start to finding the best minimum risk pesticide for your needs.
