A friend of mine had problems with carpenter ants, much like your problem with termites which can cause as much damage to a structure. It started in her shed as well and ended up in her home.
If you have termites in your shed you may want to take precuations so that they don't end up in your home as well.
Termites are ever determined in their pursuit of food - they can eat up your house, and your furniture! This insect generally feeds on approximately 2.3 linear feet of a 2 x 4 of wood per year. A colony of termites, which ranges from a few hundred to a few million, can cause major property damage.
Below are some tips to help you protect your home from termites:
Check for wood touching the ground. Regularly inspect wooden structures, and remember to store wood on a tarp, not on damp soil.
Check for water leaks. Inspect your home for water seepage. This is not always easy, so you might want to hire an inspector to investigate for you.
Check the foundation. Inspect your homes foundation to make sure that there is no water accumulation near it; this will also help avoid future repair work to the foundation. Do not store your firewood on the ground against the foundation.
Check with local pest control companies. Many pest control companies offer a free investigation of your property for termites. They will point out the risks around your property, provide you with important information, and may suggest preventative measures. Give them a call and inquire. The bottom line is prevention.
