Remedial timber treatment

If the timbers in your roof need treatment please check first whether bats are present since some chemicals are extremely toxic to bats. Once sprayed on the timbers the bats ingest the chemicals while they groom themselves. Older chemicals such as Lindane leave a poisonous residue for some time so the bats may be killed even if they are not present during the treatment work. Modern chemicals, such as permethrin or borax based treatments, are mostly less toxic to bats but treatment should still not be carried out while the bats are present. If you think bats use the building contact us for information on the appropriate timing and chemicals to use.
