Are aphids camped out on your roses? Leaf miners munching away at your prized lemon tree? It’s enough to send you scrambling for the quickest, easiest solution. That’s understandable. Just please don’t look for that solution in the chemical aisle at the hardware store, compromising the health of your backyard “habitat” and your pocket book. Integrated pest management (IPM) offers a research-based alternative to chemicals that is economical, environmentally friendly, and it works!
Pests in the home landscape may be an insect or other arthropod, plant disease, weed or other organism that negatively affects plant health or becomes an annoyance to people or pets. IPM is an approach to managing those pests that respects the interconnection and inter-dependency of all organisms. IPM is used to solve pest problems while minimizing risks to people and the environment.
Using a combination of IPM methods, like biological, cultural, physical and chemical creates unfavorable conditions for pests. Biological control is the use of natural enemies, like a ladybug, to control pests, such as aphids. Cultural controls are practices that change the environment to remove the source of the problem, like adjusting irrigation levels, since too much water can increase root disease. Physical, or mechanical, controls trap or block pests from access to plants. Barriers or screens for birds and insects are great examples of a physical control. The use of a chemical control, or a pesticide, is used only when needed and in combination with efforts of the above mentioned methods. If pesticides are needed, applying them so they minimize harm to people, beneficial insects and the environment is imperative. Check out this fact sheet from Texas A&M AgriLife Extension Service for more information on IPM.
With the average homeowner in need of problem-solving techniques to manage landscape pests, The Woodlands Township Environmental Services Department is presenting a FREE class on Integrated Pest Management in the Home Landscape. Texas A&M AgriLife Extension Specialist in IPM and board-certified entomologist, Wizzie Brown will offer practical research-based information to support implementing IPM in your own back yard. Wizzie shares specific tools for use in the home landscape to strengthen plant health and reduce plant pests. You’ll take home information that can immediately be put to use in your own yard or garden.

Outweighed by a penny and powered by wings no wider than a toddler’s hand, the iconic monarch (Danaus plexippus) is right now embarking on the first stage of a migration that will cover upwards of 3000 miles, with some individuals traveling over 200 miles in a single day! They will wind their way across mountains, deserts, and cities, through multiple seasons and weather extremes, in a round-trip effort that will span five generations.
Monarchs in the United States are split into two populations, one east of the Rockies and the other west, along the Pacific Coast. The western monarchs spend their winter in California. Those to the east winter in the mountainous oyamel fir forests of southern Mexico.
It’s now in early spring when the eastern monarchs descend from the oyamel firs and move northward through Texas, allowing us to re-appreciate their beauty and marvel at their incredible stamina, navigational abilities, and the unique spectacle that is the monarch migration.
An epic journey
As temperatures warm and days lengthen, monarchs finish their development which was suspended over the winter, become reproductive and begin mating with fervor. Once mating completes, around February and March, the females leave the males behind in Mexico and head for the milkweed that is now sprouting across Texas.
And so the migration back to the United States and Canada begins.
The energy expended to complete this first leg of the journey is tremendous. After six weeks or so, now March and April, the female monarchs must find a milkweed leaf on which to deposit their eggs before they die. Once laid, four days will pass before the eggs hatch into voracious eating machines – baby monarch caterpillars.
Monarch caterpillars feast night and day on the leaves of their host plant and, incredibly, will gain 200 times their body weight in just two weeks. When the feasting ends they form their chrysalis and spend the next 10 days metamorphosing into an adult butterfly, vibrating with color and ready to renew the march north. This is generation 1, the offspring of the butterflies that overwintered in Mexico.
Several more generations will live and die over the summer, travelling further afield, but just one generation will make the entire journey back to the oyamel firs beginning in October.
The fall migration is even more dramatic than the spring, after reproduction has bolstered the population, dozens and even hundreds can be spotted hourly.
Creating safe havens for pollinators in our yards and communities provides vital waystations during spring and fall migrations.
The migration in crisis
Once 700 million strong, monarch populations have now crashed. It’s estimated the eastern population has plummeted by more than 85% while the western population is suffering even more – only 28,000 were counted this winter. Multiple issues are to blame:
Habitat loss and fragmentation. Over 160 million acres of monarch habitat has been lost to development since 1996. Illegal logging of the overwintering sites in Mexico is also taking a toll.
Climate change. The increased frequency and intensity of extreme weather events can devastate migrating populations. Because of the incredible density of monarchs in the overwintering grounds, severe freezes there are catastrophic.
Pesticides and herbicides. Milkweed used to grow throughout corn and soybean crops across the south and midwest. But herbicides have driven milkweed to near extinction in these agricultural landscapes and depleted monarch populations along the way. Monarchs are also being impacted by neonicotinoids, a new class of insecticides that spread their toxins through the plant’s tissues. Caterpillars that dine on these plants quickly perish.
OE. Ophryocystis elektroscirrha (OE) is a parasite that infects monarchs, causing them to die in the pupal stage or emerge deformed. Milder infections result in shorter life spans and an inability to fly properly. OE pervades in our area as non-native tropical milkweed (Asclepias curassavica) continues to grow through the cooler months, after native milkweeds have died back. Follow these important steps if you choose to grow tropical milkweed.

At first glance, a pollinator garden may look like any other pretty flower garden. But for a garden to be a haven for native bees, butterflies, and moths, it needs to meet their needs for all life stages. And the most important ingredient are plants rich in nectar and pollen to feed adult pollinators and host plants specific to butterfly species. Here are simple guidelines for creating a pollinator garden that will reward you with three seasons of garden visitors and help protect these vulnerable insects.
Choose a sunny spot.
Most blooming plants require sun. Four hours of sun is ideal, but a minimum of two to three hours will work too. Some great nectar and pollen plants thrive in part shade (two hours of sun with dappled shade the rest of the day).
Native plants support more than 29 times the number of insect species than non-native plants. Aim for at least 70% of native plants in your garden. (Print the PDF for recommended plant list.)

Salvia blooms spring through fall.
Plant host plants.
Host plants are where the female butterfly will lay her eggs and her young caterpillars will feed. Some butterfly species—like the monarch and some swallowtails—only have one host plant. It is vital, therefore, to include some of these plants to support these species. Most of our host plants are native, but some are non-natives well adapted to our area. By including these host plants, you’ll welcome more diversity into your garden. (Print the PDF at the bottom for recommended plant list.)

Pipevine hosts the pipevine swallowtail.
The queen caterpillar like the monarch, only feeds on milkweed.
Adult bees and butterflies like some variety in their diet, just like us. By including different varieties of plants, your garden will attract a diverse assortment of pollinators.
Plant for three seasons.
Pollinators that overwinter in our area start emerging as the weather warms, and that could be late February to early March. As the weather turns cool, bees and butterflies go into hiding. As a general rule, they can’t fly when temperatures fall to 55 degrees. Bumblebees and some solitary bees will hibernate underground; other solitary bees will hibernate in nests they create in rock crevices and dead wood tunnels . Honey bees don’t hibernate, but buzz all winter keeping the hive warm—only the queen hibernates. The monarch butterfly is the only migrating butterfly in North America and usually leaves its overwintering site in central Mexico in March, returning in November. You can track their migration each season at journeynorth.org.
With pollinators active and needing food spring through fall, it’s important that your garden provide blooms each season. (Print the PDF at the bottom for recommended plant list.)
Plant in dense color blocks.
Avoid planting different plant varieties singly. Go bold! Group a minimum of five to seven of the same plant to create large swaths of color in your garden. This helps pollinators find them. A dense planting has another advantage. When host plants especially, are planted densely, the young caterpillars have a better chance of survival by hiding from predators.
Include a puddle.
If there’s a low area that holds water after a rain in or near your pollinator garden, leave it! These “puddling” areas are great for providing certain butterfly species (like male common buckeyes) with necessary minerals and nutrients. You can create your own puddle by filling a shallow pan or plate with soil, some rocks, and pieces of a kitchen sponge and keeping it wet.
Shelter can take various forms, from a nearby fence or trellis, dense shrubbery, or a man-made bee house for solitary bees. It can also be as simple as leaving a pile of fallen leaves and pine needles in a nearby spot. Shelter provides safe places for caterpillars to pupate, and for overwintering pollinators.
If you already have tropical milkweed in your garden, be sure to cut it to four to six inches of the ground every October to prevent the spread of OE and interference with normal migratory behavior. Consider planting native varieties of milkweed. Learn more about OE and tropical milkweed, and native milkweed species for our area in our recent blog post.
