How Can You Make Your Home and Yard Safer from Lyme Disease?

Lyme Disease is something you just don’t want. Rich has had it twice. It was no fun, and he was lucky. Nearly as soon as symptoms appeared, he visited our family physician.   She prescribed a powerful antibiotic that worked wonders and left him with no lingering problems. Unfortunately, many Lyme Disease victims suffer pain and fatigue for years.  It’s serious.

Lyme is often transmitted to a human from a bite by a tiny tick that picked up the disease bacteria from an infected white-footed mouse. It once was thought that deer were the primary carrier but mostly they are host to a tiny larval tick that infects a mouse that allows another tick to infect a person.

In theory, eliminating white-footed mice from a yard and home will greatly reduce the odds of transmission of this disease to people. Killing all of them isn’t feasible but reducing their numbers is.

About White-Footed and Deer Mice

White Footed and Deer Mice are amazingly common across much of North America.  They’re the cute, native mouse, not to be confused with the common house mouse that originated in the Old World.

White Footeds naturally live in dry temperate forests with brush. That perfectly describes suburban landscaping. It’s likely that five to 20 white-footed mice live in close proximity to most suburban families. They’re nocturnal and rarely seen.

Here are some characteristics:

• They’re hoarders. Find a cache of corn, dog food, or acorns in a shoe or empty can and you’ve found a white-footed mouse cache.
• They reproduce like crazy. A 44-day old female can become pregnant and bear a litter after 22 to 28 days. Babies become independent in three weeks and soon begin having their own babies. Mom often has two to four litters a year.
• They don’t live long. A year-old mouse is elderly.
• Foxes, weasels, hawks, owls, coyotes, and many other predators love dining on mice.
• White Footed mice enjoy coming into homes, where they often find food and enjoy a furnace’s warmth. They can bring with them disease-bearing ticks.

Prudent homeowners carefully manage ticks, in part by reducing white-footed mice numbers. The fewer mice that live near people the lower the odds a person will contract Lyme Disease.  So, managing mice and ticks makes for a healthier home and yard.   Here are a few tips:

To reduce mouse populations and entry to homes:

• Welcome mouse predators. Karla Bloem, Executive Director of the International Owl Center says, “Two actions people can take to encourage owls are to protect large dead trees that aren’t a threat to people of buildings should they fall. Owls love them. Also, building and erecting an owl house can welcome owls to live near a home and catch and eat mice.” Barred owl nest box plans, and plans for many other birdhouses, can be found at www.nestwatch.org.
• Plug up holes that allow mice to enter a home and replace worn or broken weatherstripping. This is an important fall maintenance that also keeps cold drafts outside and reduces heating bills.
• Avoid feeding mice. They love dining on dog or cat food left in a dish overnight or birdseed left under a feeder. Only feed pets and wild birds what they can eat in a short time. Then, pick up and clean the pet bowl.
• Use snap traps to kill mice in the house. Avoid poison. A poisoned mouse can stagger outside to be caught and eaten by an owl, which can sicken or die from the poison.

A Few More Ways to Reduce Lyme Disease

In addition to reducing mouse numbers and applying a vaccine to keep survivors free of Lyme Disease bacteria here are a few other ways a person can do to reduce odds of infection:

Use Permethrin:   When applied to clothing, not skin, this chemical repels and kills ticks.  Rich purchased several sets of clothing from the Insect Shield Company that are impregnated with permethrin. Supposedly the tick-killing effectiveness lasts for 70 washings. The chemical is also available in spray cans to apply to any clothing.

 

 

 

Do Tick Checks:   After being outside, strip down and check the body over for ticks.   Then take a hot sudsy shower. Ticks usually crawl around on a person for several hours before biting. A tick merely walking on the skin can’t infect a person.

Thank and welcome opossums:  New research indicates that opossums are tick vacuum cleaners. Ticks climb on them, but these primitive mammals groom often and eat the ticks they remove from their fur and skin. If you have a possum living in the yard be happy.

An Emerging Tool in the Battle Against Lyme Disease

A new product is being developed and tested by a major research company. It is an oral nontoxic vaccine placed in small baits. When strategically positioned around a yard, mice not yet infected with Lyme bacteria eat it and become resistant to the bacteria. Mice uninfected by Lyme can’t spread the disease to a person. If all goes well this product will be on the market by 2021 and may be a major help in reducing human cases of Lyme Disease.

Lyme Disease is an awful condition. Taking precautions to reduce the odds of being infected makes sense.
