In late summer and early fall, it may become necessary to control wasps (including yellow jackets) in your yard. It is good to take care of the menacing insects before finding one inside your pop can as you are about to take a sip!
In August and September, these yellow stripey bugs can become aggressive scavengers. They are especially drawn to dead animals, fallen tree fruit, and picnic food. This may threaten outdoor activities including barbequeing and gardening.
Honey Bees vs Yellow Jackets and Wasps
The first thing to do is correctly identify the insect. Wasps have a slender body, cylindrical legs, and appear to have shiny smooth skin. Yellow Jackets are a different kind of the same variety of wasp. They are typically more aggressive, though their sting hurts less. Bees are full-bodied and very hairy compared to yellow jackets. Their hind legs are flattened for collecting and transporting pollen. (Try to leave the bees alone so they can do their pollinating!)

How to Get Rid of Wasps and Yellow Jackets
We recommend using Wasp Rescue Traps. They work like a charm for yellow jackets, wasps, and hornets (read instructions carefully when dealing with nests and insects). At our Portland Nursery, we carry the traps to suit your needs, and would be happy to answer any questions you may have.
How to Keep Yellow Jackets Away from a Picnic
there’s nothing worse than having a beautiful picnic ruined by pesky wasps or yellow jackets
If you are heading to a picnic or camping trip, we have a wasp solution for you! Rescue makes a small, flat trap that is easy to pack in your picnic basket. Camp dinners will be more enjoyable with one of these traps hanging from a nearby tree.
When Do Wasps sleep?
Remember to be careful when dealing with stinging insects. It is best to set up traps in the evening when the temperatures cool and wasps slow down. Always read and follow instructions carefully.
Many gardeners have heard that ladybugs might be positive additions to their gardens, but may not fully understand why. Furthermore, they may even have a NEED for ladybugs, but don’t know how to attract them, or keep them sticking around once there. Perhaps you’ve purchased ladybugs from your local nursery, only to release them and watch them fly away somewhere else that they’d rather be.
This confusion leaves many gardeners with gardens full of “bad bugs” like aphids and mites, and in need of a healthy, natural solution.
If you’re looking for a solution on how to keep aphids and mites away from your garden, in a safe, natural, organic way – ladybugs are the answer. This guide will teach you how to not only attract them, but keep them there. And, as an extra bonus, how to remove ladybugs once they’ve outstayed their welcome.
Why You Should Want Ladybugs in Your Garden
How to Get Rid of Aphids – Ladybugs for Pest Control
Ladybugs help control bad insects, like aphids. In fact, ladybugs are one of the most effective predatory insects around – and love to make a meal out of bad ones. In particular, aphids, mites, and scale. We can not emphasize enough the importance of not introducing chemical pesticides to your garden. If you’re looking for how to get rid of aphids, introducing ladybugs to your garden (and keeping them there) is the answer.
Remember that good bugs are living creatures and they have feelings, too. The way you keep ladybugs around is simple if you know what you’re doing – treat them right, provide them what they’re looking for, and they’ll stay on patrol, guarding your plants and keeping your garden free of bad bugs for as long as you need them.
How to Attract Ladybugs
Ladybugs are no different than other animals or insects. They’re a living thing, and like all living things, they are more likely to remain in your garden if there is a ready supply of food and water, and the conditions are right to keep them happy. Be sure there is water in your garden, in addition to food sources. Either turn on your sprinklers frequently, or consider having very small “bowls” of water – these could be bowl-shaped rocks that water can collect in. Don’t expect a bug to be able to get water from a bird feeder or anything significantly larger than themselves without drowning themselves !
Ladybug Foods – What do Ladybugs Eat?
Ladybugs love to eat other pests. Their favorites just so happen to be destructive pests like aphids, mites, and scale. Besides pests, they’re also interested in nectar and pollen. So, if you can’t provide them bugs to eat, there are still ways to attract them there by planting pollen-producing plants.
Plants and Flowers That Attract Ladybugs
It is important to provide ladybugs with an alternative food source when meals of pest insects are scarce. Flowers produce nectar and pollen, which ladybugs also need to survive. Plan your garden to feed beneficial insects by choosing a variety of plants that will bloom as many months of the year as possible.
There are many plants that attract ladybugs, but some we would recommend include
yes, this is actually what a garlic flower looks like above the ground
Don’t be surprised if the ladybugs leave after they have removed all your bad insects, though.
They will only stick around for as long as there is a good food source in your garden…which brings us to our next point…
Make a Ladybug Feeder
If you are interested in keeping ladybugs around for reasons beyond pest control – maybe you just love the way they look. They are pretty cute, we wouldn’t blame you. Consider making a ladybug feeder! This will ensure they stick around your garden. If and when those pesky bad bugs DO return, then you’ll have security guards on call 24/7!
Where to Buy Ladybugs and How to Release Them
Your neighborhood nursery should sell ladybugs. If you happen to live in the Pacific Northwest, visit us at our Portland Nursery and Garden Center in the Raleigh Hills neighborhood.
When you’ve brought your ladybugs back home, it is best to release them in the evening just after the sun has gone down, and just after you have watered the garden. This will help keep them in the garden, as typically they are dehydrated upon their release and won’t be able to go far. If there is water aplenty, they’ll be motivated to stick around and make themselves at home. Then, assuming they find a food source, they’ll know that this is paradise they’ve been dreaming of, and there’s no place they’d rather fly off to!
It is also better to release them in small batches all around your garden rather than in one big group; otherwise, they might get all huffy and start duking it out for the territory.
How to Get Rid of Ladybugs
Remember what we said in the beginning of this article – Ladybugs are living creatures, and like all living creatures, they will flourish when there is plenty of food and water. If you have a “ladybug problem” (if that exists), and you have a presumably good reason for wanting them gone from your garden, it’s a matter of simply removing their food sources, and they’ll soon fly away to seek a new place where they can find it.
To remove ladybugs from your garden, remove plants that create pollen from your garden.
We always strongly advise to NEVER use pesticides in your garden. Yes, they’ll kill the ladybugs, but they’ll potentially ruin your entire little ecosystem, by introducing harmful chemicals to the mix. Remember, a garden is a natural ecosystem. Yes, you can control certain aspects of it, and it might be tempting to solve the problem quickly, but for the sake of the rest of your plants, do it in a way that doesn’t harm the balance of the rest of your ecosystem and the rest of your garden will continue to flourish and thank you.
Why are there notches all over the leaves of my rhododendron? The answer is most likely Root Weevil. Root Weevils are little beetles about ½” long that appear in the late spring and early summer.
They prefer to feed on the tender new growth of rhododendron plants in the northwest. They also enjoy eating several other plants that are favorites of gardeners. You can find them on yews, hemlocks, strawberries, salal, huckleberry and several others.
Adult root weevils are night feeders spending their days just under the soil surface staying cool and hiding from predators. The best way to know if you have root weevil is the distinctive notching on the edges of the leaves.
Weevil Larva: The Root Weevil Life Cycle
An adult root weevil will lay its eggs in the soil under your favorite rhododendron in mid-summer. Those eggs will hatch into larvae in late summer to early fall where they will over-winter in the top layer of soil feeding on the fine root mass of the plant. As they grow, they will become more destructive feeding on larger and larger roots and even the base or trunk of the plant. As the soil starts to warm in the spring, pupation takes place and the larvae will become an adult. The adult will forage on leaves for 20-45 days before it is able to start producing it’s own eggs. One adult can lay around 200 eggs in its life span of 90-120 days.
How to Get Rid of Weevils
There are many chemical insecticides on the market that can control root weevil but they are tricky to use and are harmful to beneficial insects. Timing is key when using chemical insecticides. You will need to know what stage of life the root weevil is currently in and that changes from year to year. A granular grub control on the soil can wipe out the root weevil in its larvae stage if they are actively feeding at the time. A foliar insecticide can kill the adults if they are feeding as well. If they are not actively feeding you will just be wasting time, chemicals and money and root weevils are only actively feeding about 40% of their life.

This is the most effective way to control root weevils. Use beneficial nematodes. Nematodes are small round worms that don’t get any bigger than 1 cm. They can be safely applied to the shrub and surrounding soil without use of masks, gloves or protective equipment. They are harmless to pets, wildlife, beneficial insects and us but they do quite a number on the root weevil. They actively seek out both the larvae and adult root weevil. They bore into the body cavity and release a bacterium that quickly kills the root weevil.
They can be applied from early spring through fall and be completely effective. You can purchase Beneficial Nematodes at our Portland Nursery and Garden Center in the Raleigh Hills neighborhood!
Bud worms can be a real problem. If your petunias and geraniums are budding but they won’t bloom. Why is that? The answer could be the tobacco budworm also known as the geranium/petunia bud worm.
Life Cycle of a Bud Worm
Here’s what they do. The adults start to emerge as a tan to brown small moth mid March through mid April. They seek out the buds of flowering plants or the terminal growth (the ends of new growth) where they lay an egg. They will lay many eggs over their short lifespan. After a short time, the egg will hatch and the larvae will instinctively bore into the end of the bud where it will devour the blossom inside. The larvae are yellow to green in color but will take on the color of the blossom they just ate. Red geraniums will turn the larvae red. They will emerge from the bud and slowly make their way to the soil, eating any tender growth they can find on the way down. In the soil they will start the pupation process and turn into an adult moth and the cycle starts all over again. There could be as many as five generations in one summer.
What do Bud Worms Like to Eat?
Although the budworm moth was known to only inhabit the southern regions of the country, they are creating quite a problem for gardeners in the great northwest. They have been quite successful over-wintering in the soil as a pupa. They will attack almost any tender flowering plant but they are best known for eating the buds of petunias, geraniums and nicotiana plants. They will also go after many vegetables, especially cabbage.
How to Get Rid of Bud Worms
Here’s how to kill them. Almost any insecticide will kill the budworm when it’s actively feeding but won’t do anything to the moth or pupa. A bacteria known as spinosad (spin-OH-sid) will attack the budworm throughout all stages of life. The most commonly known product that contains spinosad is Captain Jack’s Dead Bug Brew. We sell this at our Portland Garden Center Just spray it on once every few weeks and the problem is solved.
