Bat  control in Iowa

There are about nine different species of bats found in Iowa, the types of bats that are
most commonly found using attics for roosting and nursery colonies are Big Brown Bats
and Little Brown Bats. They often share the same site, and while in some cases only a few
bats may be using the structure, it is common to find colonies of several hundred in
homes. Larger buildings such as churches will sometimes have colonies of thousands of
bats. Our goal is to successfully resolve conflicts between property owners and bats using
methods which compliment bat conservation.  

The Little Brown and Big Brown bats roost usually in homes and structures where they
can enter through areas as small as a quarter of an inch.  A bat proofing process is
needed to resolve any situation where a building, home, or structure is infested with this
type of animal. Most homeowners make the mistake of sealing entrances and openings to
prevent bats from gaining access into their structure, but in a many cases, seal areas that
the bats are using to go
out of the structure. When this is done it will force the entire
colony of bats down through the living quarters of the house, which can be a very messy
and dangerous situation.

Bat exclusions are needed to remove bats from buildings and structures. All of the cracks,
holes, crevices, anything the size of a quarter inch or more are sealed, and then bats are
funneled through one-way doors or tubes out of the structure. After this process is
complete (a week to ten days) the whole colony has been removed.
What to do about them and how to get rid of bats in Iowa

The bat exclusion process requires several steps. The first step is an inspection to find out
the main entrance points and the amount of bats we are dealing with. We will get on your
roof, look in the attic, and use ladders to thoroughly go over the structure.

The second step involves sealing all gaps, cracks, and holes, leaving the primary entrance
points open. This prevents them from finding an alternate access point into the structure.

The third step is to install one-way exclusion devices that allow the bats to leave your home
but not return into the structure.

After at least two weeks, the valves are removed and the access holes are repaired and
sealed. This is the final step in the exclusion process.

The exclusion process starts with an inspection and a quote for complete exclusion.  The
price of the inspection is waived if the customer completes the exclusion process with
Complete Wildlife Control.  The value of the exclusion process varies depending on size of
the structure, safety concerns, amount of ladder time involved, height and distance traveled
to get to the location.

It is impossible to give an accurate estimate without looking at the structure in question.  
Most houses in central Iowa are in the $650-$1100 range for complete exclusion.

Bat exclusion is warranted for two years and that can be extended with annual inspections.

In Iowa, young bats are present in nursery colonies from early May through early August.
Excluding the mother bats during that period would create a problem even worse than
having the bats in your attic, as the young bats would die without their mother to feed and
care for them. The problems associated with a large number of dead animals in a structure
can be serious, so waiting until the young bats can fly is the sensible method. It is possible
to perform exclusions in the spring, but spring exclusions must be completed by the middle
of May to eliminate the possibility of stranding young bats in the structure.
