Poison Ivy Growing Among Woodsorrel

Whenever I take a walk around our house, I keep my eyes open for poison ivy. In the past couple weeks it seems to have awoke from its seasonal slumber and is ready to take off. The sooner you can control poison ivy the better. In order to control it well, it is important to understand this persistent plant.

The old saying “leaves of three, let it be” has been most helpful for me over the years to keep from getting confused between poison ivy and other look alikes. Poison ivy is a climbing woody vine that loses it’s leaves each winter. Leaves are egg shaped with three leaves per petiole that may be toothed, lobed, or entire. Poison ivy attaches to trees and rocks with aerial roots, which may have a hairy, fibrous appearance. Leaves may take on a reddish hue late in the season. It reproduces by creeping stems, roots, and seed transported by birds. Poison ivy can thrive in many areas that other plants do not.

All parts of the plant contain resins that cause allergic reactions for most of the U.S. population. These resins cause issues if burned, directly touched, or indirectly transferred from one surface to another. Resins are continually present on the leaves, stems, and roots, even in the winter.

Poison ivy is often confused with Virginia creeper, which is a creeping and trailing vine that secures itself to objects with specialized stems call tendrils. Virginia creeper has 5 leaflets, instead of three and is not poisonous. Poison oak is another common mix up. Poison oak has three leaflets, but the leaves look very similar to a classic oak leaf. The lobes have blunt tips and hairs on both the top and bottom of the leaf. Poison oak is not a creeping weed, but rather grows upright from the soil surface. For this plant the “leaves of three, let it be” statement still applies.

Poison ivy and poison oak are responsive to glyphosate, triclopyr, and 2, 4-D herbicides, which are commonly used in poison ivy killers. Always follow the label when using a herbicide and wear adequate protective gear while handling!

Banishing Bed Bugs

Recently I heard through the county grapevine that there have been some local cases of bed bugs (Climex lectularius). I have not identified any infestations myself and I hope that will still be true in 2017. In any case, it is always good to be prepared to address a situation such as this. So, let’s start by debunking a prevalent myth about bed bugs:

“Only dirty people get bed bugs.”- False. This is absolutely false.

The spread of bed bugs is more related to the movement of people than it is to cleanliness. However, it may be more difficult to treat or diagnose a case of bed bugs in cluttered spaces and within displaced groups of people, rather than in a spotless environment. Bed bugs are arachnids that are exclusively mobile by crawling. They are sensitive to light and will hide in dark crevices, such as bed frames, mattress seams, and base boards, which is why people often notice bites before they notice bugs. The most obvious sign of bed bug presence is black speckles of feces on crevice surfaces. Bed bugs often use carpeted areas to approach new hosts and climb into luggage, purses, clothing and more.

After hitching a ride to a new environment, they make a new home in your home. You probably won’t notice the first day, or even the first week. That means that by the time you do notice them, they have multiplied. A female bed bug typically lays about five eggs daily throughout her lifespan, which can range from 6-12 months. Eggs hatch into the first of five nymph stages within 4-12 days. Although bed bugs require a feeding between each nymph stage, they can survive for extended periods of time without a meal.

Biting occurs at night and there is usually no pain to the host during the act of biting. Residual effects of the bite can cause mild to moderate skin irritation for 1-2 weeks. Bed bugs rarely transmit disease.  All in all, they are a severe annoyance that is very challenging to eliminate without professional intervention.

If you suspect that you have bed bugs in your home or business get a positive ID. Sticky traps near hiding areas are effective for collecting specimens. Another method that works well is to use clear tape to capture a specimen and secure it to a white or clear surface. Then examine the specimen to confirm if it is or is not a bed bug. Professionally assisted eradication is the most effective method for ridding your environment of these pests. It is very difficult to get effective control using only cultural methods or only with pesticides. It will require a combination of both and may take multiple attempts. Always check furniture for signs of bed bugs when you spend the night away from home and also check before bringing new furniture into your home.

If you fear that you have encountered bed bugs while traveling, there are steps to take to reduce the risk of spreading them to your home. Upon your return, bag and seal clothing and other belongings before you enter and immediately heat treat whatever you can in the dryer. Proceed to washing items in hot water and drying them again. Exposure to high heat will kill bed bugs. Vacuum any upholstery or carpet that you may have contacted on the way in.

Getting bed bugs is not the end of the world, but it can be embarrassing and difficult to treat. I hope that you do not encounter bed bugs, but if it happens hopefully you will know what to do after reading this article.bed_bug_lifecycle
