As an entomologist and pest control specialist, I’m often asked about common garden pests. People want to know how to identify them, what damage they can do, and most importantly, how to get rid of them!

In this article, I’ll cover the basics on identifying and controlling some of the more common garden pests. I’ll start by going over identification tips for each pest. This is important because it will help you better understand their behavior and habits so that you have a successful plan in place for dealing with these pesky critters.

Then I’ll explain the best methods for preventing infestations as well as how to control existing ones. By the end of this article, you should be armed with enough knowledge to keep your garden safe from harm caused by these little buggers!


Aphids are one of the most common and destructive garden pests, with an estimated 10 to 20 thousand species worldwide. It’s no wonder that aphid infestations can be so disastrous for our gardens; a single female can produce up to 800 offspring in her lifetime!

To help alleviate this issue, it is important to understand how we can control them through natural predators and companion planting. Natural predators such as ladybugs, lacewings and hoverflies feed on aphids and their larvae. These beneficial insects should be encouraged by providing habitats in which they thrive – plenty of flowers nearby will attract these predatory insects.

Additionally, companion planting with certain herbs or vegetables such as garlic, chives or radishes can also deter aphids from your plants. Planting nasturtiums near cabbage is another great way to protect against the presence of aphids. It is essential to have knowledge of the lifestyle cycles of both helpful and harmful bugs when dealing with pest management issues like aphids.

Taking some preventative measures early can make all the difference in keeping our gardens healthy and productive. By using tactics such as controlling natural predators and companion planting wisely, we can reduce the likelihood of having a major outbreak on our hands. Moving on then…


Having discussed aphids and their control, let’s now turn our attention to caterpillars. These larvae of moths and butterflies can cause great damage to a garden if they’re left unchecked. They’ll chew through the leaves of your plants, leaving them looking raggedy and stunted in growth. So it’s important that you identify any potential caterpillar infestations early on and take steps to control them before serious damage is done.

One way to do this is by encouraging natural predators into your garden. Beneficial insects like ladybugs or green lacewings will happily feed on young caterpillars and keep their numbers down. You can also introduce parasitic wasps which lay eggs inside the bodies of mature caterpillars – when these hatch, the larva consume their host from within! Other methods include manually removing them with tweezers or picking off egg masses found under plant leaves.

It’s also worth noting that some varieties of caterpillar are actually beneficial for your garden – so don’t go spraying everything indiscriminately! With careful observation and prompt action, you should be able to manage an outbreak without harming those helpful species.

Onward then to whiteflies, another pest which needs controlling…


Hey everyone, let’s talk about Whiteflies today!

First, let’s go over how to identify them – they’re tiny white insects that usually fly around when disturbed.

Once you know what you’re looking for, it’s time to talk about control.

I recommend using an insecticidal soap or horticultural oil to kill the adults, and using yellow sticky traps to catch the adults before they lay eggs.

Good luck controlling these pesky little critters!

Identifying Whiteflies

Ah, whiteflies! They’re one of the most common garden pests around, and you might be able to spot them if you look close enough.

Whiteflies are tiny insects that can cause a lot of damage to plants – they feed on the sap of leaves and stems, which weakens their overall growth. If left untreated, whitefly infestation could even lead to disease transmission or plant death in some cases.

Identifying whiteflies is surprisingly easy since they’re so small; adult whiteflies are about 1-2mm long with clear wings bordered by gray veins. You’ll likely find them hovering over your plants during warm days, making it easy to spot them when they’re flying away from your touch.

Apart from spotting actual individuals, you may also notice yellow spots on the upper side of leaves where the adults have been feeding – these spots usually indicate an existing infestation.

The best way to control whiteflies is through integrated pest management techniques such as removing affected leaves or using insecticides adapted for this kind of problem. It’s important to act quickly once you’ve identified an infestation because whiteflies reproduce very fast and can become hard to get rid of if ignored for too long.

Controlling Whiteflies

One of the best ways to control whiteflies is by introducing natural predators into your garden. These beneficial insects help keep their population under control, without having to resort to chemical solutions that can harm other parts of your ecosystem.

Ladybugs, lacewings and parasitic wasps are some great examples of natural enemies you could introduce in order to get rid of whiteflies.

But if the infestation is too severe, then insecticides may be necessary. Make sure you read up on the kinds available so that you can choose one adapted for this kind of problem – there’s no point trying something that won’t work!

It’s important to act quickly once you’ve identified an infestation because whiteflies reproduce very fast and can become hard to get rid of if ignored for too long.

By following these tips, you should have a better chance at effectively controlling any future outbreaks of whiteflies in your garden. Remember – prevention is key when it comes to keeping pests away from your plants, so take all necessary steps as soon as possible!


Mealybugs are a common garden pest that can spread quickly, making them an especially difficult problem for gardeners. In fact, the population of mealybugs in gardens has grown by over 400% since 2014!

Mealybugs have several characteristics which make them particularly troublesome:

  1. They feed on plants’ sap and excrete a sticky honeydew substance onto leaves;
  2. They reproduce rapidly;
  3. Their bodies are covered with wax-like filaments that serve as protection from predators and insecticides; and
  4. They can spread plant diseases like powdery mildew or root rot.

Fortunately, there are some natural solutions to controlling mealybug populations, such as introducing beneficial insects like ladybugs or lacewings into your garden – these predatory bugs will help keep mealybug numbers down without harming other insects or animals living in your environment. Additionally, you may want to consider using horticultural oils applied directly to affected areas of the plant, though this method is only effective when treating small infestations due to its limited coverage area.

Slugs and snails present their own unique challenges for gardeners…

Slugs And Snails

As an entomologist and pest control specialist, I’m here to tell you that slugs and snails are some of the most common garden pests. They can be difficult to identify because they come in all shapes and sizes, but one thing is for sure – they’ll make your life a lot harder if left untreated!

Slugs and snails feed on foliage, flowers, fruits, vegetables and other organic matter. This means that not only will your plants suffer from their feeding damage but it also increases the risk of disease transmission as these creatures crawl over them.

The good news is there are plenty of ways to combat these pesky intruders without having to resort to chemical solutions or traps. Organic solutions like companion planting with garlic or using diatomaceous earth can help keep slug and snail populations down naturally.

You could also introduce natural predators such as hedgehogs or chickens into your garden which will happily feast on any unwelcome visitors! Lastly, making sure you regularly remove decomposing plant material from your garden helps prevent infestations by providing less food sources for the pests to eat.

In order to reduce the number of slugs and snails around our gardens we need to take action quickly and use effective methods that don’t harm our environment. By implementing organic solutions alongside natural predators we can drastically reduce their numbers while still maintaining healthy plants in our outdoor spaces.
