Sunflowers, snapdragons and marigolds galore! Our garden is finally beginning to pop after a chilly start to the growing season. Today I'm sharing a guide to organic pest control in the garden, based on my own experiences! Let's go on a garden tour and I'll share what tasks I am working on this month!
The golden rule of gardening is that nature decides when plants will thrive, regardless of the gardener's efforts!
Zone 6B Garden
My growing zone is 6B and typically runs from the beginning of May through the end of October. I am able to use covers and grow lights to extend this season slightly, but ultimately the plants are at the mercy of Mother Nature.
This season has been slightly unique in that we haven't experienced our typical Kansas weather. We had a hard freeze in early May that affected the cherries, blackberries bushes and apple trees.
We covered them with sheets as best we could, but the harvest is going to reflect the harsh cold snap. May in Kansas is usually warm and sunny, but this year it was cool and wet. My garden is about three weeks behind where it usually would be at this time, but now it is rapidly catching up.

Common Garden Pests
We have been battling squash bugs and caterpillars creeping and crawling all over our tiny vegetables. Organic pest control in the garden has been heavy on my mind this year. The vegetables most affected are the zucchini and cabbage. It's important to me that we avoid chemical pesticides, so I am currently researching methods for organic pest control.
What I have found so far is to hand pick the squash bugs and eggs and remove them from the garden. I've been dropping them into a bucket of soapy water or smashing them. I also have learned that we need to be practicing better crop rotation with the pumpkins, squash, zucchini and cucumbers.
A little too late for this year, but definitely something I will implement next spring!
I have previously tried using Seven and Diatomaceous Earth for pest control. Both work, but I've decided not to use Seven anymore if it can be avoided. Check out my IG post below to see how I applied it.
While these are both good options, this year I am going to use Neem oil and essential oils. Neem oil is extracted from the fruits and seeds alike of the neem plant, or Azadirachta indica.
The unique composition and fragrance of Neem make it quite beneficial for eliminating all manner of pests and diseases from the garden. It’s safe to use on houseplants and in greenhouses, and can even be used as a fungicide, helping to smother fungal infections like scab, rust and powdery mildew.
Neem Oil
Neem is detrimental to pests and causes many species to lose their appetite while stunting their growth and reproductive processes. I also don't have to worry about harming beneficial pollinators, earthworms in the soil, along with many other important microbes and bacteria. Just make sure to apply the neem at night so that it is dry before the pollinators arrive the next morning. Neem repels pests and doesn't harm the pollinators. Win-win.
Neem oil is a little controversial in the wild world of gardening. This is my first season using it, so I don't feel qualified to give an opinion, however I DO want to share why it might not be the best choice for your garden.
Neem can be irritating to the skin and eyes. When using Neem, it is important to wear proper PPE, including gloves and glasses. It is very important to discontinue using Neem three weeks before harvest to avoid consuming the oil. Ingesting Neem can cause digestive issues, which makes sense when considering that our gut is full of bacteria!
How to Use Neem Oil
To use neem oil, mix according to the directions on the bottle. I am treating an existing squash bug outbreak, so I will be applying the oil weekly. When I apply neem oil, I use a garden sprayer to mist the leaves and stems. Always lift the leaves to spray the underside! For pest prevention, apply every ten days. I recommend testing the neem oil on a small area before applying it to all garden plants.
Essential Oils for Pest Control
Essential oils aren't just for making your house smell good, they can also be used to repel garden pests! There are four ways to use essential oils in the garden: DIY sprays, infused cotton balls, hanging strips of infused cloth, infused string.
To deter ground-moving mice, squirrels, cats and dogs I use cotton balls with 4-5 drops of essential oils scattered around the area.
To repel deer or dogs, I use hanging strips of cloth for an essential oil infused 'scarecrow.' String soaked in essential oils works best for deterring flying insects. I hang the strings between the rows of plants.

Can free range chickens manage garden pests?
Well.... yes and no. Our garden is surrounded by a chicken run that allows the ladies to snatch grasshoppers and other pests that try to sneak into our garden. If you have never watched a chicken chase a grasshopper, you should probably stop reading and hop over to youtube. They are hilariously awkward and efficient.
They are also very efficient at removing garden plants, especially seedlings. I actually have wire tunnels covering my flowers and vegetables to keep the hens from destroying the garden with their scratching, pecking and taking dust baths. Personally, we keep them OUT.
The Potato Trick for Roly Poly Bugs
I live in an area where roly poly bugs (aka pill bugs, doodle bugs, wood shrimp, wood lice or armadillidium vulgare) are common. While this isn't a problem for my garden in most years, there are times when these little pests run wild.
Roly polies are beneficial bugs in compost piles, but when their population grows, so does their ability to destroy garden veggies. This year I am battling these bugs as they have aggressively been eating my tomatoes. My first line of defense for organic pest control is by manually removing the roly poly bugs from the garden. Rather than picking them by hand, I use a potato!
Cut a potato in half and hollow out the center. Place the potato upside down in the garden near the plants that are being consumed. Every twelve hours, lift the potato carefully and remove it from the garden.
That's a Wrap!
My best advice to a gardener who wants to manage damaging insects naturally would be to aggressively prevent the infestation from happening. We knew last summer that the squash bugs were worse than ever, but I did not treat the soil with neem oil or remove the straw mulch that they love to hide in. This year the battle is going to be even harder, and I knew better.
Organic gardening requires grit and a strong will. It is so easy to get frustrated and buy an insecticidal spray. We see honeybees and other beneficial pollinators in our garden and harming them for a few extra zucchinis would be such a tragedy.
I'm going to mix up some neem oil and apply it to the squash tonight around sunset. I'll also dip string in peppermint essential oil and drape it around the base of the plants. With a little luck and a watchful eye, hopefully the squash bugs infestation will be over soon.
