Questions & Answers

Many of our customers are amateurs, who just want to find out a little more about these fascinating creatures. We therefore receive a number of questions about the detectors and about using them, and so we have tried to list some of these with answers below. If however you have further queries, then please do not hesitate to email us on the link at the bottom of the page, and we will endeavour to answer them..

What time of year is best for bat detecting ?

Bats are in hibernation throughout the winter, first emerging towards the end of March, but it is during the summer months that they are at their most active.

What time of day are bats most active ?

They are most active at night, usually being most easily observed just after sunset when they emerge to feed and they are also very active an hour or two before dawn. They often enjoy multiple feeding periods during the night, but this activity is likely to be interrupted by night roosting and can also be affected by the level of moonlight and weather conditions.

Are there particular weather conditions that are conducive to bat detecting ?

Absolutely, bats enjoy warm weather and dislike the wet. The summer months are the best time to find them, but the most important factor is the temperature. On cold evenings, there are very few insects for them to feed on, and therefore there will be very few bats out. Similarly, strong winds or heavy rain can reduce the insect density, and again you are unlikely to find many bats. In addition, of course, the conditions are unpleasant for you and your detector !

What are the best habitats for finding bats ?

They are often found close to water, particularly still or slow moving water, where there will be many insects. This will be even better if it is bordered by wooded areas. They are also found in and on the edge of woodland, hedges, and other places that are sheltered by trees.

What is the range of a bat detector ?

it is impossible to put a definitive range on a detector as their effective distance is affected by obstacles and atmospheric conditions in the same way that any sound travelling over a distance would be. Range will be reduced by factors such as high winds or barriers like walls and doors, but they will still work in such circumstances if the distance is small, and they are sensitive enough to detect sounds over quite a large distance in good conditions.
