Soft ticks differ from the hard ticks in that their body shape is oval and the head and mouthparts are hidden underneath the body. Soft ticks also are more flesh-like in appearance and do not have the hard, flattened exterior of ticks such as the brown dog tick, American dog tick and similar species. The most commonly encountered soft ticks around buildings are those that infest birds and those infesting rodents. Rodents transmit the spirochete that causes relapsing fever. In rural homes and other secluded buildings that become infested with rodents, may potentially house soft ticks. Should the rodents leave or tick populations become too high, the ticks may attach themselves to persons residing or sleeping in infested buildings. Bird or fowl ticks may be encountered on farms where poultry are kept or in buildings infested by pigeons that carry the pigeon tick. These ticks are quite mobile and may crawl significant distances seeking hosts, such as invading a structure on a farm or moving down through a building from pigeon roosts.
Soft ticks will be present wherever their rodent or bird hosts live. Rodent burrows, attics, wall voids and crawl spaces are just a few examples.
Tips for Control
When soft ticks are found within a building, it is recommended consulting a professional for assistance. The birds or rodents serving as hosts must first be controlled and/or excluded. Further steps must be taken, ensuring rodents or birds cannot re-enter the building. It is important to remove any rodent or bird nest that is accessible and also treat cracks and voids where ticks may be located.
Should you discover a tick imbedded in your skin, do not grasp it by the abdomen and pull. You may squeeze its fluids into your skin, which increases the chances for infection. Use a syringe or a fine-tipped tweezers to grasp the tick by the head next to the skin and slowly pull backwards. Working slowly will permit the tick to withdraw its mouthparts so they do not detach and remain in the skin to become infected. Once the tick has been removed, cleanse the area well with soap and water. You may want to disinfect the bite site with alcohol or apply an antibiotic cream.
