Protect Against Pests with Good Insulation

Pests are a common problem for homeowners whether they be bugs and insects or larger pests such as rodents. One of the leading causes for pest problems is the insulation of a home. To protect against several different types of pests, homeowners should consider if their home has foam, cellulose, or fiberglass insulation and what types of chemicals they have put to repel any unwanted guests.


One of the most secure ways to keep out any pests as well as unwanted air and breezes is spray foam, also known as cell spray foam. This type of insulation expands into the small crevices and cracks of walls and ceilings, providing an airtight seal. Unfortunately, this type of insulation is prone to mold growth if it is not protected with an anti-mold chemical compound. As far as pests are concerned, this is one of the better options as it expands almost 100 times its original size and can easily block any access points pests might find. Luckily for the home owner, spray foam insulation is the number-one rated insulation for being flame retardant. It is also well-known for not absorbing water that may find its way into the house.


A more traditional form of insulation, cellulose has been used in houses for several decades. There are two methods to using this type of insulation: hand-packed or blown-in. Unlike foam, this insulation may not get all the nooks and crannies. Therefore, it is important to apply chemical pest-control and repellents with the insulation. Cellulose is also notorious for moving, shifting, and settling. This means that it may need to be applied several times at the onset to ensure a tight seal. After it has finished settling, however, pests are less likely to try and use it for bedding.           


Alongside cellulose, fiberglass is another traditional form of insulation. It is entirely hand-packed into the appropriate spaces and usually comes in long panels. This means that, out of the three forms of insulation, it has the least air-tight seal. Repellants and pest-control sprays must be applied before and after use of fiberglass to keep out pests. On the brighter side, fiberglass is relatively inexpensive and can last for longer amounts of time than Cellulose or Foam. Unfortunately, pests and rodents enjoy this form of insulation for building nests and housing and seeking warmth during winter periods.

Just In Case

Regardless of what type of insulation is in a home, it is always important to know how homeowners insurance can be of service. Insurance companies, such as seen in the review of Lemonade Insurance sometimes provide discounts  depending on the type of insulation that is inside the home. In the same, these companies may have discounts with insulation installation and maintenance companies. Because insurance companies are less likely to provide any form of assistance against pest or bug damage and control, having good insulation can be the crucial first step to avoiding any serious problems or costly situations.
