Bat Prevention - How to Keep Bats Away

There is no effective repellent spray or granules. There is no sound machine that will affect bat behavior. The only way to keep away bats is to block off their entry holes into your building. If you already have a bat problem, then there is no point in doing so now. You need to first get all the bats out of the house or building. This is done, generally, by:

  • 1. Watch the house at dusk, and identify all bat entry and exit points.
  • 2. Seal up all secondary exit holes, and install one-way exclusion devices on the main exit areas.
  • 3. Observe the bat behavior, ensure that the devices are working, and leave them in place for 3 days.
  • 4. Only if you are sure all are out alive, remove the exclusion netting and seal the entry holes shut.

Bat Prevention Tips - something not commonly used or looked for until you have been infested by them. The only problem with this train of thought is that once the bats are already in your home, it can be very difficult to get rid of them, especially if it is during the warm months of spring and summer, where the bats will be raising your babies in the upper areas of your home, and it is illegal to try and move them.

The high risk areas for a bat infestation include Northern America and Canada, and also any areas close to a water source, as the bats love to eat the bugs that dwell in this area. The southern states are also affected, but by a different species, which still causes a problem nevertheless.

Prevention is better than cure, and in reality, there is only one prevention tip that you will need to follow – completely seal your home. You can turn to all of the gimmicks in the world – the high frequency noise equipment, using radios in attics, moth balls, chemical sprays, and plenty of other things that are commercially sold to prevent e bat infestation, but the fact of the matter is these things do not work, and you are only costing yourself a small fortune in the long run.

A team of experts or one on its own is the best thing to use for bat prevention. They will do most of the hard tasks for you, such as ensuring that there are already no bats in your home, and also then moving around in a precise fashion around the outside of your home to ensure that there are no holes that could potentially be used as an entrance or an exit for the little flying creatures.

Of course, should you decide to save a bit of money and do the task yourself, you are going to need pointers in the right direction. You are going to want to scale the outside of your home twice – once at night and once during the day. This will help you to find all of the holes. The daytime hours will allow light through holes so you can see from the inside of your home out, and the nighttime hours will allow you to see where the bats are flying – this could point you in the right direction of an entrance. With the help of a torch, a notebook and some skill, you need to systematically work around your home to jot down any holes. This means the following areas:
  • Look in the attic for the source of light outside to come in
  • Check where the fascias meet the roof
  • Check for any loose or broken tiles on the roof
  • Check the soffits
  • Make sure that there are no vents open, or with holes to allow entrance
  • Check the chimney
Once you have done this both at night and during the day, you will need to look at the notes you have made for yourself and buy materials which will then help you to block the holes. Ideally, you are going to want to use heavy duty wire netting for the problematic areas of the roof, especially if you cannot afford to replace many broken tiles. Also, a heavy duty polyurethane sealant will help to sort out all the other holes and crevices. Metal sheeting can be used for the really big holes too. A hole to the bat might not necessarily mean a whole to you, so remember that these creatures are small and can fit through even the smallest of gaps. Even if it seems too small to fill, fill it up anyway just in case. You never know where these creatures could be gaining access to your home.
