Smaller bat species require an opening no wider than 3/8 inch, a hole the diameter of a dime. The Transonic PRO uses strong ultrasonic pulses to jam the bat's own ultrasonic echoes. Over a few days, fewer and fewer bats will attempt to return to their nest and they'll go elsewhere. The recommended strategy is to aim the speakers at the general area where bats habitat. ...day and night. This creates a hostile environment for them forcing them to abandon their nesting area. It is also helpful to clean or add disinfectant to the areas of their droppings. Using the Transonic PRO is also helpful even when complete exclusion is applied. It will help prevent the nesting site from being re-established.

Effective at repelling brown recluse spiders

Transonic PRO for bat control: $59. For bat control repels bats, brown recluse spiders, and mice.Broadcasts ultra sounds at the frequency bats navigate..."jamming their sonar". These sounds also create a hostile environment driving bats out of attics, and from under soffets.

BAT CONTROL The only sure way of getting rid of bats in a building is to prevent their access. First, locate the entrance holes to the roost. By watching the building at dusk, it is often possible to see exactly where the bats are coming out. During the day, you can look for bat droppings (they look like mouse droppings) stuck on the wall of the building or accumulated in piles on the ground. The entrance to the roost will be somewhere above the droppings. The entrance usually is surrounded by a narrow dark brown oil smear (the oil and dirt rub off the bats as they enter the roost). Bats squeak and rustle as they crawl in the roost and this helps pinpoint exactly where they are located. When searching for entrance holes, remember the rule of thumb - a bat can probably squeeze through any space big enough for your thumb to fit through.

Attempts to remove bats from buildings should not be conducted in June through August. Young bats, not yet able to fly, will be trapped inside where they will eventually starve.

This is the time to use the Transonic PRO. You don't have to worry about accidentally trapping bats inside (exclusion). Plus it's almost impossible to seal up the building entirely because bats can get into such tiny openings.

Frequently Asked Questions about Bats

What species of bat is in my home or structure?
The main species which roost in attics or other human habitats in North America, are: the Little Brown Bat; the Big Brown Bat; or the Mexican Free-tailed Bat.

Will the bats leave my home in the fall?
The Little Brown Bat will normally migrate to caves for the winter and return to the same home or structure in the spring. The Big Brown Bat can over winter in your home or structure. Bats can live up to 30 years, and are very territorial, they will not leave your home or structure, unless they are properly excluded.

What should I do if I come in contact with a bat?
If you are bitten by a bat - or if infectious material (such as saliva) from a bat gets into your eyes, nose, mouth, or a wound - wash the affected area with soap and water and get medical advice immediately.

Will a professional bat removal company use any chemicals in my home?
No chemical is registered or effective against bats.

How do bats move around in the dark?
All bats can see, but some use a special sonar system called echo location. These bats make high frequency calls either out of their mouths or noses and then listen for echoes to bounce from the objects in front of them. They are able to form pictures in their brains by listening to reflected sounds just like we form pictures in our brains by interpreting reflected light with our eyes. In this way, bats are able to comfortably move around at night, avoiding predators, maneuvering around obstacles, locating their food, and capturing insects in total darkness.

What do bats eat?
There are nearly 1,000 different species of bats in the world, living on every continent except Antarctica. Each one has developed special adaptations for how it lives and what it eats. For example, 70% of all the bats in the world eat insects and many of them use echo location in order to find food and move around in the dark. Many small insectivorous bats can eat up to 2,000 mosquito-sized insect in one night.

What should I do if I find a lot of bat guano? (After I've removed them or driven them out)

If you find a buildup of guano in your home be sure to act immediately and remove it. There are all types of microorganisms which can flourish in their fecal matter - histoplasmosis possibly - which could present a hazard to you. For dropping removal you should wear a respirator. Be sure to use one with good filters and charcoal. This will help filter out any noxious gas associated with cleanup. Be sure to wear some old clothes you can throw away, Once all droppings have been bagged in some type of strong plastic Hefty bag you can start cleanup. Use a strong disinfectant. It should kill off all virus and bacteria as well as remove some of the smell.

Variable frequency technology
Weitech's products emit ultrasonic (some units emit ultrasonic and sonic) sound waves that help repel targeted pests from the protected area. Independent laboratory tests have shown that Weitech's products produce the highest sound output (decibels) over the broadest frequency range (hertz) of any of the competitive products tested.
