When it comes to bats, exclusion is really the only means of moving them away from your property. Bats spend so much of their time airborne that it’s challenging to try to trap them. And if you do, then you have to work out what you’ll do with them. Commercial repellents are ineffective, and attempts to poison bats will cause more problems – without getting rid of the bats.
What’s the best method for bat control? Read on to learn more.
Bats can’t roost where they can’t access. Exclusion prevents bats from accessing your attic or barn and works even if the bats have already moved in.
- Watch at dusk and dawn to see where the bats are coming and going from.
- Get a ladder, climb up to inspect where the roof and walls meet, and look for any gaps. Signs that bats are using any entry point include brown stains around the entrance, and bat droppings (guano) stuck to the walls below.
- Install exclusion doors over one or two main entries and seal the rest up with mesh or sealant (such as caulk).
- For larger areas, you can also install exclusion netting to deny the bats’ entry.
Exclusion should never be used during maternity season. During this time, the roost will be full of baby bats that are unable to fly and care for themselves. The season runs from mid-April to late August, during which time it is illegal to use exclusion or any other control methods on bats. Once the young have grown old enough to fly, you can legally use exclusion.
There aren’t any effective repellents for bats, so don’t waste your money. Any “ultrasonic emitters” or similar devices have already been declared as fraudulent by the Fair Trade Commission, so steer clear.
Bats are constantly airborne, so standard traps are useless, and homemade traps require just as much time and energy to build as to employ exclusion.
Once you’ve caught the bats, what do you do with them? It is unnecessary and unlawful to kill bats, which means you need to release them and hope that you’ve appropriately sealed your attic so that they don’t return. This is one of the many reasons that it’s better to use the exclusion doors: save yourself the trouble and the bat from potential harm.
CAN I USE POISON?
Poisoning the bats isn’t really an option. There’s no way to get bats to eat the poison (as their diet consists of flying insects), which means that it’s generally delivered through fumigation. However, the bats will crawl away in between the walls to try and escape the gas. This has three outcomes:
- They get stuck between the walls and die
- They come out into your living space, flying around the room in a panic
- They manage to get into the open, sick and distressed
