If you cannot afford to have the bat guano removed by your bat removal professional, leave it alone. Do not try to learn how to remove bat guano from attic. Bat droppings do not smell. Bat urine has a very distinctive odor and often there are times that homeowners do not even notice it. If your bat removal professional can smell bat urine inside the living or working area of a structure, it means the bat problem could be out of control. During hot humid weather your bat removal professionals often get calls from customers whose houses or buildings smell because of a bat infestation that has not been dealt with. In most of these situations, a major cleanup of bat droppings and contaminated insulation in necessary. Small infestations of bats usually do not produce enough bat urine odor that can be noticed inside. However bat populations grow quite large over time and it is best to have your bat removal professional get rid of bats before the bat colony causes damage to the structure.

Bat droppings are called guano and it is an important fertilizer in many tropical regions because of its high levels of phosphorus and nitrogen. Unfortunately, guano can be very bad for humans, and must be taken care of in a very specific way.
Before you attempt bat guano from house, you should learn about the effects of inhaling bat guano first. Bat poop is dangerous. One of the dangers of bats in attics is that they have the potential to produce a lot of bat excrement and bat urine. The color of bat guano is dark brown to black when it is fresh and light brown when it is dry. Bat droppings, bat scat, bat poop, bat guano or whatever you want to call it can or will create a bat guano health risks. Bats produce more than three times their body weight in potentially toxic bat droppings every week during the summer months when they are active. Bats fly from late in the evening at dark to the early morning before daylight, so they need to ingest a lot of calories to fuel their several hours of flying. What goes in a bats mouth must come out and a lot of insect consumption equals lots of bat droppings. It does not take long for even a small number of bats to foul up your attic and interior wall voids if they are not dealt with quickly. Depending on the size of the bat colony, a nasty little fungus called Histoplasmosis that bats can excrete in their droppings and will grow in moist piles of bat droppings. If you directly inhale Histo spores, you could end up quite sick and depending on your age and respiratory health, you could end up blind, with permanent flue like symptoms or in extreme cases dead.
With all this in mind, the truth is that the majority of bat droppings found in attics and walls are harmless if undisturbed. The thought of bat guano in your attic may be disgusting, but no threat to your health. Only a small number of bats contract Histoplasmosis and excrete the fungus in their droppings. Still the fungus can’t grow unless the piles of droppings are very large.
Small amounts of bat poop in your attic or walls is not a threat to your health unless the bat guano is disturbed. Undisturbed bat droppings are the safest bat droppings. You would have to directly inhale the Histo spores from the bat guano to even potentially get sick. In most cases of bat guano abatement is not necessary and a waste of money. Your bat professional can get rid of bats in attic and perform bat exclusion before the bats make too much of a bat guano biohazard, but your USA Bat Removal professional can only advocate the abatement of bat guano from attic and walls in cases where the bats have left A LOT of bat guano. Bat guano removal should only be recommended by your bat removal professional under the following circumstances.
1. Large accumulations or piles of bat guano.
2. You have a respiratory illness.
3. You are pregnant or have small children in the house.
4. The attic space is being used for storage or a kids play room.
5. There is ductwork in the attic that leads to the living areas of the structure.
6. The heating and air system is in the attic.
7. You are planning on renovating the space or are tearing out the walls/ceilings that may have bat droppings behind or on top of them.
8. You are changing the insulation. Insulation companies will offer to remove the insulation fairly cheaply for you but they should not be used for this purpose as they do not have the proper OSHA training or safety equipment needed to remove Bat guano safely. (The proper HEPA filtered respirators, air scrubbers, vacuums, and suites similarly used for asbestos and mold abatement). If an untrained insulation worker or wildlife control operator becomes sick you could be liable.
9. If you plan to sell the house or building, bat droppings typically become a red flag for home or commercial building inspectors. Uneducated buyers are often told the worst case scenario and will want to back out of the contract regardless of the amount of bat guano.
10. If you just cannot stand the thought of the bat droppings in your house or building. It is up to the customer to determine if they want to live with the bat guano or have your bat removal professional remove them.
If there is a small colony bats in your house or building, you really have no need to worry about the bat droppings left behind. If you encounter a small amount of scattered droppings somewhere in your home or building, just pick them up with a wet paper towel and flush them down the toilet. Under no circumstances should you try to clean-out bat guano from the attic yourself. Big box store dust-masks and even full face respirators are not adequate equipment to safely work around bat droppings in confined spaces like an attic. Remember , undisturbed bat guano is the safest bat guano.
